was captured in Ceylon by Thwaites in 1872. In Prof. Krieger's
work on the genus Xanthopimpla (Bericht. d. Xaturf. Ges. zu

The female was described from material collected by Col. Bing
ham in the Himalayas of Sikkim. There is in the Calcutta

species with some confidence, since it differs from the description
of the female in little but its immaculate fourth and sixth seg-

This species is said by its author (Zoc. cit.) to be easily dis-

Cameron tells us (/. c.) that " this species is closely related to
X. binghami ; it is larger, has all the marks on the abdomen
separated, those on the first segment are distinctly narrowed on
the inner side, not dilated there ; the inner keel of the lateral
areae forms a broad, rounded curve, without angle, it being also
wider compared with the width [sic], and there is an area, open on
the inner side, which does not exist in X. binghami" How far
these points will prove constant one does not yet know. The
species is unknown to me.
