T. D. A. COCKERELL. 
is clearly seen to be furnished with strong bristles — the beginning of 
a ventral scopa. 
The type of Glyptapis is G. mirabilis, but four species occur in 
the Collection, separable thus: 
Wings very dark ; stigma large . G. fuscula n. sp. 
Wings hyaline . 1 
1 . Stigma and nervures ferrnginons ; 
length of marginal cell 935 p G. reducta n. sp. 
Stigma and nervures dark brown ; 
length of marginal cell over 
1200 p 2 
2. Entirely black; mesothorax 
punctate G. mirabilis n. sp. 
AVith metallic crimson tints on 
abdomen ; mesothorax reti- 
culate G. reticidata n. sp. 
The insects are more or less covered with „Schimmel“, owing to 
the inclusion of air and moisture, so that it is difficult at times to 
interpret the sculptural characters. Some misconceptions may have 
arisen from this cause, though I have tried to avoid them; but the 
larger features — e. g. the ridges on the metathorax, cannot be in 
any sense illusory. 
Glyptapis mirabilis sp. nov. 
Entirely black; length a little over 5 mm, anterior wing 3 3 / 4 mm; 
abdomen very stout, convex, moderately shining, with a sericeous 
lustre, finely hairy, (the hairs plumose on sides of first segment,) and 
without punctures. 
Clypeus and face ordinary, flattened, dull and obscurely punctured ; 
anterior edge of clypeus not dentate; malar space short and broad, 
its length 85 — 102 p; eyes hairy, about 595 p across, not allowing 
for convexity; front distinctly punctured, with very short fine hair, 
and longer stout bristles ; antennae ordinary, flagellum quite thick, not 
long, very minutely pubescent; scape rather bent; first flagellar joint 
globose, strongly separated from the rest; ocelli normal, large, in a curve. 
Mandibles broad, with a long cutting edge, which is notched 
near the apex, and thus bidentate, so that when the mandibles are 
closed there is left a little space, nearly square; the long inner edges 
are somewhat concave, and so do not exactly meet, except at the 
inner point and that next to the notch.
