Ill 
DIAGNOSES OF ACULEATE HYMENOPTERA 
By LIEUT.-COLONEL C. T. BINGHAM 
^ A S it is impossible to include in the present volume the full report on the 
X Aculeate Hymenoptera, in which one hundred and seventy-four 
species are recorded, it has seemed best to publish Colonel Bingham's 
new diagnoses in an appendix, postponing the bulk of his paper until a third 
zoological part of Fasciculi Malay enses can appear.'

$ . Head, thorax, and legs black, abdomen bright red, the basal four-fifths of the first 
and the whole of the apical segment black, wings hyaline for a third of their length from base 
and beyond that fuscous with in certain lights a purple sheen, the face in front, the scape of the 
antennae at base, the pronotum, a fringe round the scutellum posteriorly, the median segment 
above, and the legs covered with glistening, silvery pubescence, abdomen at base and at apex 
with black, on the intermediate segments with more sparse, rich golden pubescence. Head 
densely coarsely punctured, seen from the front broad, almost as broad as long, the vertex 
gently arched, the ocelli on a raised plane, the eyes emarginate on the inner side towards the 
top ; below them the face is slightly constricted, mandibles arcuate, clypeus with a strong, 
broad, short medial longitudinal carina, antennae somewhat thick, the scape deeply grooved in 
front. Thorax densely punctured, short, broader than the head, the mesonotum with two 
medial and two lateral longitudinally impressed lines, scutellum conical, projecting, median 
segment closely punctured, broad, obliquely truncate posteriorly, above with two lateral outwardly 
arched and two medial V-shaped carinae running from base to apex of truncation ; legs comparatively 
long, wings ample, the fore wing with three cubital cells, the nervures black, the tegulae large, 
smooth, polished, and shining. Abdomen shining, the base and apical segments closely punc- 
tured, the remaining segments smooth, with a zone of punctures beyond their middle ; basal 
segment constricted, somewhat campanulate, with a well-marked carina beneath, this last widely 
but slightly emarginate in the middle ; pygidium convex, bearing in the middle a slightly raised 
oval tubercle, which is smooth and shining.
