1922] Hijmenopterous 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, shghtly 

 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 Harpagocryptus. 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 httle 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 

 tibiae, posterior ones twice as long.
