triquetraoi Olivier, nor of Robineau Desvoidy, nor does it belong to
Ervia Desv. It is, however, the species so determined by Coquillett.
The frontal bristles descend one bristle lower.

Figs. 65. 66. Aporia limacodis. This is a true Aporia, not a Mac-
quartia. The head is that of a female. Dexia tristis Walk, seems to
be an Aporia, bvit quite impossible to identify from the description.

Figs. 67, 68. The figures agree with a male cotype of Leiicostoma
nigricornis, except that the third antennal joint should be the same
length as the second. I consider nigricornis and senilis distinct and
will give reasons elsewhere.

Figs. 69, 79. Siphoplagia anoniala. First vein bristly to opposite
end of auxiliary, and third vein to opposite origin of apical cross-vein.

NORTH AMERICAN DIPTKRA.



Figs. 71 and 76. Xanthomelanodes arcuata. Figure evidently
made from an oblique viewpoint. Xanthonielana is preoccupied in
Aves (Bonaparte, 1850).

Figs. 72, 75. Sarcomacronychia, sp. Not Pachyophthalnius. I
five elsewhere distinctive differences.

Figs. 73, 74. Goniochcsta plagiodes. A small costal spine some-
times. The frontal and parafacial bristles usually appear as a con-
tinuous row, the latter directed downward. The foremost frontali
inserted opposite base of third joint. There are three procHnate orbi-
tal bristles in each sex, the middle ones sometimes weak.

Fig. 78. Siphona illinoisensis. Differs from geniculata in the
widened and flattened third antennal joint, convexity of third aristal
joint, etc.

Figs. 80, 81. Euthera tentatrix'. The second antennal joint is
sometimes almost as long as the third, the latter in such case being
shortened so as to make the antennae scarcely longer than face. The
third joint is normally of equal width throughout; truncate at tip.

Fig. 82. Drepanoglossa lucens. The anterior upper fronto-orbital (re-
clinate) bristle is stronger than any other save the vertical. I give
elsewhere the differences between Epigrhnyia and Drepanoglossa.

Figs. 84, 85. Euthyprosopa petiolata. Compared with cotype the
front pair of ocellar bristles is longer than shown in figure, and third
antennal joint is pointed at apex. The frontal bristles are sliorter.
The hind cross-vein may be nearer the angle of the fourth vein in
some specimens than in others.

Fig. 87. Chcstogcedia acroglossoides. Apparently the male of Fron-
tina acroglossoides Towns. I give elsewhere distinctions between this
species and Baiinihaueria analis Wulp, with notes on ChcFtogcsdia,
and an allied new genus. The figure should show the outer row of
frontal bristles differentiated from the bristly hairs of parafrontals and
the second antennal joint longer to agree with eastern specimens
which I am inclined to identify as this species.

Fig. 89. Atropharista jurinoides. I give reasons elsewhere for
maintaining this genus.

Fig. 91. Eujurinia pollinosa. I propose this name for //v^/r?V?a
polluiosa Wulp. A specimen from Mexico differs from the figure in
the somewhat wider cheeks and the not bowed palpi.

Fig. 92. Euclytia flava. I propose the new geniis Euclylia for Cly-
tia flava and give particulars elsewhere.

Fig. 93. Neofischeria flava Towns, n. g. et n. sp. The genus and
species are characterized elsewhere. This is not Demoticus venatoris
Coq. , which by the way is not a Demoticus, and for which I propose
the new genus Parafischeria. The figure should show the well de-
veloped palpi, which are elongate, a httle thickened distally and
slightly curved.

Fig. 94. Hyphanirophaga hyphantricE, male. The parafacials be-
low and the cheeks should be narrower to agree with topotypes in the
National Museum.



TACHINID^. 381

Figs. 97, 98. Plagiprospherysa valida. The parafacials are not
so wide below in tototypes in the National Museum. The species is
apparently closely allied to P. parvipalpis, but needs comparison.

Fig. 100. Pseudohystricia ambigua, male. The genus differs from
Jurinella in the wider parafacials and more produced front.

Fig. loi. Saundersia sp? Can not be a Neniorcea, which has the
epistoma less prominent and the face more receding and lengthened.

Fig. 105. Muscopteryx sp. Probably M. chcEtosiila.

Fig. 106. Compared with a cotype there is a pair of short reclinate
fronto-orbital bristles opposite the ocellar pair, wanting in figure.

Fig. 109. Achcstoneura archippivora, maXo.. This is Achcstoneura
and not Frontina. Notes on the distinction will be published else-
where.

Fig. no. Senotainia flavicornis. t\i\sisdi\s\\wQ.\.iro-a\.rubriventris.

Fig. III. Gcsdiopsis s-^'i This maybe tnexicana, but is not the
species so determined by Coquillett, which I shall describe as a new
genus and species, Poliophrys sierricola.

Fig. 112. Stofnatodexia analis. If Dexia analis Say is congeneric
with Dexia diadetna Wied. and the species figured is correctly iden-
tified with the former, it is incorrect in having the first posterior cell
end so far from the wing tip.

Fig. 113. Bombyliomyia abrupta. The arista is longer than the
third antennal joint.

Fig. 1 14. Chcetoglossa picticornis. The figure lacks the long and
extremely delicate proboscis.

National Museum, June, 1907.

LIX. Family HIPPOBOSCID^.




Fig- 159- Pseudolfersia fumipennis, enlarged. After Lugger.



Head flattened, usually attached to an emargination of
the thorax; face short; palpi forming a sheath for the
proboscis, not projecting in front of the head; anten-
nae inserted in pits or depressions near the border of the
mouth, apparently one-jointed, with or without a ter-
minal bristle or long hairs. Eyes round or oval,
ocelli present or absent. Thorax flattened, leath-
ery in appearance; scutellum broad and short. Halteres
small or rudimentary. Abdomen sac-like, leather}^ in
appearance, the sutures indistinct. Legs short and strong,
broadly separated by the sternum; tarsi short; claws
strong and often denticulated. Wings present or absent;
the veins always approximated to the anterior border,
with less strong ones running obliquely across the wing.

The flies of this family are always parasitic in the adult
condition upon birds and mammals ; they have a pecu-

liar louse-like appearance, and one often encounters
them in handling recently killed birds, especially the
raptorial birds. They have a quick, short flight, seek-
ing the beard or hair of the collector within which they
run nimbly, seeking to hide. The following table is
based chiefly upon Speiser's studies of the genera of the
world.

LX. FAMII.Y STREBLID^.

Head of moderate size, with a freely movable neck.
Byes, when present, small, unfacetted, or with very few
facets. Ocelli wanting. Antennae inserted in a pit, two-
jointed, the second joint with a bristle. Proboscis short,
not protrusible, thickened at base. Palpi broader than
long, not forming a sheath for the proboscis, projecting,
leaf like in front of the head. Abdomen with a distinct basal
segment, the other segments rarely distinguishable, the
first segment with peculiar bristles for the protection of
the wings when at rest. Hind coxae always enlarged; fifth
joint of tarsi usually enlarged and elongate. Claws
never distinctly toothed; pulvilli present. Wings some-
times wanting or vestigial; when present the surface
pubescent and the veins rather stout.

sively parasitic upon bats. Their breeding habits are
not well known. Kolenati believed them to be oviparous,
but Speiser is of the opinion that their breeding habits are
not unlike those of the Hippoboscidse.

3. Legs of usual length (3) . .... Aspidoptera.
Hind legs greatly elongated, twice the length of the body {Pter el-

LXI. Family NYCTERIBIID^.

Small, spider-like, wingless flies. Head oval, folding
back when at rest in a groove on the dorsum of the tho-
rax. Antennae short, two-jointed, the oval terminal
joint with bristles inserted in tubercles. Eyes and ocelli
vestigial. Thorax depressed, laterally anteriorly with
comb-like bristles. Abdomen oval, with more or less
distinct segmental scutes. Legs long, the knees at rest
prominent above the thorax. Femora broad; tibiae club-
bed or shovel-shaped; metatarsus very long. Halteres
pedunculate or sessile, in the latter case often indistinct.

This family includes a considerable number of species,
distributed widely in different parts of the world, all of
them parasitic upon bats. Various attempts have been
made to divide the group into smaller genera, but not
with much success, Nycteribia being the only well defined
genus known. Penicillidia differs in the more aborted
and sessile halteres, and the species are of larger size,
but I doubt its validity.

APPENDIX.

During the printing of this work several genera new
to America have been added in recent publications; other
changes or additions I have ascertained by the examina-
tion of types. The student is requested to insert marginal
references in the body of the work wherever such changes
or additions should be made.

Page 35, Mr. Austen urges the abandonment of the term 'metatarsus',
and I quite agree with him that the word, as used, is etymologically
incorrect. Whether or not distinctive terms for the different tarsal
joints are desirable I do not know, but I suggest the following: pro-
tarsus, epitarsus, ynesotarsus, metatarsus, onychotarsus.

Page 167, second line, insert flagellum of before 'antenna'.

Page 168, Mr. Verrall informs me that the real difference between
Neoexaireta and Actina is the ocular pubescence of the latter. He
also adopts the name Chorisops Rond. in lieu of Neoexaireta.

Page 181, for 'Alisonia' read Akronia, and for 'Acanthina' pre-
oc. read Acanthinomyia Hunter. Myiochrysa coerulia is a syno-
nym of Sargus viridis, according to Verrall.

Page 180, near bottom, for 'Hamatopota' read Haematopota.

Page 185. An examination of the type of Nothra americana Big. in
Mr. Verrall's cabinet discloses the fact that the species is rightly
placed. The venation is quite like that of Pterodontia^ save that there
is only a slight angulation in place of the costal spur. This character,
however, is not generic; it is disregarded in Opsebius. Mr. Verrall
separates the genera by the presence of but a single aristal hair in
Nothra, three in Pterodontia, but considering the differences used in
generic separation in this family I think Nothra should be suppressed,
Same page, for 'Appeleid' read Apelleia.

Page 191, couplet 3, last line, insert often after 'proboscis.'

Page 197, et seq. Asilidae. The distinction between the Leptogas-
trinse and Dasypogoninse is apparently bridged over by a new genus
from Brazil, represented by a specimen in my cabinet, of which a fig-
ure is here given. The form is quite intermediate between Leptog as-
ter and Plesiomnia. I am unable to make out the structure of the
palpi.

APPENDIX. 389

Dr. Back, who has examined the type of Sphageiis^ distinguishes
the genus as follows:

"Front and middle femora with a patch of short, stout bristles below;
third antennal joint without excision on inner distal part.

Sphageus.
Front and middle femora without such patches of bristles; third an-
tennal joint with excision on inner distal part; near the prox-
imal margin of second and third abdominal segments with a
white or yellowish pollinose crossband. . . Dizonias."
Dr. Back also has made 'Habropogon' bilineatiis the type of a new
genus, with the following definition:

"Front not unusually widened above; bristles on the lateral margin
and posterior callosities and scutellar margin numerous and
well developed; third antennal joint short and broad; species
much resembling Stenopogon in general appearance.

Willistonina."
Page 195, near middle for '■fraudigerd' read sabulonuni.
Page 198, couplet 7, third line, for '7' read 8; in couplets 11 and 12,
transpose '12' and '13'.

Page 221; couplet 28 first line, for 'male' read female.
Page 203. The genus Dasyllis, according to Col. Yerbury, comprises
but a single species, the type; the American species should be united
with Laphria. In this opinion I agree. According to the same author-
ity Niisa is not a synonym for A^tdrenosoma^ which should be sub-
stituted for that word in the eleventh line.

Page 206. Mr. Verrall has resuscitated Dialineura Rond. for those
species of Thereva having a hairy front, the face bare and the first
antennal joint thickened. This definition will apply to some, prob-
ably to all of those species included under 'Thereva, pt.' in couplet
3 and should be substituted therefor.

Page 217. The type specimen of Rhabdopselaphus nius Bigot, one
of the three or four genera of this family I had never seen, in Mr.
Verrall's collection, lacks the head; otherwise it is a true Geron. Bigot
erred in ascribing three submarginal cells to the genus.

is one, having long, pictured wings and small tubercles at the insertion
of the fronto-orbital bristles. Camptoprosopella melanoptera, gen.

bare arista, etc. Siphonophysa he proposes for a new species [pectinata,
Brazil) and probably S. sordida Wied. (Brazil and West Indies) hav-
ing the arista plumose above only and a 'hinten ausgeschweiften Au-
genrand'). ChcstoccEha maybe accepted, but the other two genera I
think should be held in abeyance for the present. If they are accepted
a dozen or more of the American species of Saproniyza and Pachyce-
rina should receive new names.

Mr. Hendel republishes the earliest paper of Meigen, of which two
copies only are known to be in existence, in which scores of names,
many of them repudiated later by Meigen, antedate some of the most
common genera in diptera, and advises their substitution! He would
have deserved the thanks of a long suffering public had he withheld
these copies instead of republishing.

Page 325, Helomyzidae. A very useful review of the North American
Helomyzidse, recently published by Aldrich and Darlington (Trans:
Amer. Ent. Soc. xxiv, March, 1908) adds two new genera to our fauna.
These, together with one recently described by Coquillett (Can. En-
tom. March, 1907) may be differentiated from those given in the table
as follows:

Near Helomyza. a propleural, twodorsocentral, two fronto-orbitals,
one sternopleural bristles present {pilosus, Mass.) Achsetomus Coq.

Humeral, propleural, one dorsocentral, one fronto-orbital, no sterno-
pleural bristles present; oral margin receding, as in Anorostotna.
{johnsoni, Mass.) ...... Porsenus Darl.

A humeral, propleural, five dorsocentral, two fronto-orbital, two
sternopleural bristles present; auxiliary vein indistinct, {oregona,
litorea, Oregon, Calif.) Silig"0 Aldr.

The authors reject Heteromyza as of doubtful occurrence in North
America, leaving all the American forms easily recognized by the pec-
tinate costa. They also merge Scoliocentra into Leria, — which I doubt.

Page 334, couplet 13, for 'cell' read vein.

Mr. Townsend proposes to make the specimen illustrated in Fig.
156 the type of a new genus and species, which he will call Euepalpus
flavicaiCda. For Fig. 157, he also proposes the new genus and species
Eufabricia fl.avicans Towns.
