i i .) 22 ] Hymenopterous Genus Harpagocryptus and its Allies. 105 
Nealgoa gen. nov. 
9 . Small, 5-6 mm. in length. Head, seen from above as 
long as broad, produced medially in front, truncate behind, the 
eyes approaching close to the occipital margin; malar space 
long, greatly exceeding the basal width of the mandible 
and equalling the length of the scape, malar furrow wanting; 
ocelli obsolete. Antennae 12-jointed, long and slender, slightly 
attenuate at tips, much longer than the head and thorax to- 
gether; scape two and one-half times as long as thick; pedicel 
half as long as the first flagellar joint; all flagellar joints long. 
Palpi as in Algoa and Plarpagocryptus. Pronotum as long as 
broad, almost as wide as the head, strongly narrowed behind, 
from just before the middle; mesonotum short, twice as broad as 
long, tegulse well developed. Fore wing paddle-shaped, reaching 
slightly beyond the tip of the propodeum, with a strong costal 
vein extending almost to the tip, and with two pale, oblique 
discal veins, evidently the vestiges of the radius and submedius; 
hind wing absent. Propodeum a little longer and narrower than 
pronotum, very slightly widened posteriorly, the superior angles 
prolonged into acute teeth; posterior face concave, almost 
vertical. First segment of abdomen more or less campanulate, 
separated from the second, both above and below, by a strong 
constriction; anterior face separated from the dorsal face by an 
arcuate carina which gives off a short median ridge behind; 
spiracle at the lateral margin just behind the carina. Second 
segment the longest and widest, three times as long as the first, 
longer than wide and broadest near the tip; apical margin 
emarginate medially; third to sixth segments subequal, narrow- 
ing to the acute tip of the abdomen, each one-third as long as 
the second, with straight posterior margins. Legs long, the 
anterior femora thickened, about one third as broad as long, 
middle and hind femora stout, but neither are noticeably thick- 
ened; fourth joint of all tarsi thickened and emarginate at tip, 
very deeply so on the front pair; claws acute, simple; tibial 
spurs 1, 2, 2; front and middle tarsi much longer than their 
tibise, posterior ones twice as long.
