 pronotum quite strongly and closely punctured throughout, each puncture bear- 

 ing a very short but distinct subdecumbent hair, short, transverse, the sides 

 almost continuous, strongly convergent, evenly and moderately arcuate, the 

 apical emargination moderately deep ; elytra fully as long as wide, polished, 

 glabrous, ogival at apex, minutely but distinctly, sparsely punctate, the humeral 

 callus quite pronounced. Length 1.0-1.45 mm.; width 0.75-1. omm. California.

Body very broadly rounded, minute and subglobular 2 



2 — Piceous-brown, the median parts of the pronotum and sterna of the hind body more 

 darkly shaded ; legs pale ; head minutely, sparsely punctate, each puncture with 

 a short and inconspicuous hair ; pronotum minutely, sparse^ punctulate, sub- 

 glabrous except near the abruptly reflexed lateral edges, where the hairs are erect, 

 stiff and bristling, very much narrower than the elytra but with the sides almost 

 continuous ; elytra almost circular, glabrous and subimpunctate, about as long as 

 wide. Length 0.85 mm.; width 0.72 mm. Bahama Islands (Eleuthera). 



lateralis, sp. nov. 



Black throughout, the legs not paler ; body very broadly rounded, the head and pro- 

 notum finely but rather strongly, moderately closely punctulate, the former very 

 feebly pubescent, the latter subglabrous, with a very few microscopic hairs, es- 

 pecially toward the sides, the,latter nearly continuous, very strongly convergent, 

 with the margin very minutely reflexed ; elytra minutely but distinctly, sparsely 

 punctulate, not as long as wide, extremely obtusely ogival at tip, glabrous.

Hyperaspini. 

 Besides the genera defined below, it is probable that Tiphysa and 

 Hindu, distinguished by the elongate scutellum, can also legitimately 

 enter this tribe, which is closely related to the Scymnini, but recog- 

 nizable at a glance by the perfectly glabrous upper surface. The 

 scutellum in all the genera mentioned below is well developed and 

 equilatero-triangular. As a special peculiarity of this tribe, although 

 evident to a generally less degree in Scymnini, it should be stated that 

 the genital segment is greatly developed in both sexes, assuming almost 

 perfectly the appearance of a true sixth segment in form and sculpture, 

 and is more conspicuously developed than in any other tribe of the 

 family — in the genus Smi/ia, however, which is somewhat aberrant 

 among the Scymnini, forming a connecting link with the present tribe 

 in some respects, the genital segment is equally well developed, and it 

 is also very strongly developed in the South African Cranophorus. In 

 the males of Hyperaspis and probably Helesius, there is no visible 

 segment beyond the sixth, but in Brachyacantha and Hyperaspidius,
