strongly declivous, very concave from base to apex, and is provided 

 along the nearly vertical basal carina with an arcuate smooth ledge, 

 the apical part of the clypeus slants backwards, is strongly aculeate 

 at the tip, and penicillate there, the labrum being completely fused 

 with the clypeus without traces of a suture ; eyes large, canthus 

 very small ; antennse 10-jointed, club tri-jointed and as long as 

 the whole pedicel, third to fifth joints very angular inwardly, sixth 

 and seventh greatly compressed and sub-lamellate inwardly, the 

 seventh, however, projecting less than the sixth ; prothorax rounded 

 laterally and with the basal angles also broadly rounded, not much 

 convex ; scutellum cordate ; elytra parallel, somewhat depressed, 

 without costules or striae with the exception of the juxta-sutural 

 stria which is, however, very faint, and covers only the basal part of 

 the propygidium ; pygidium vertical, bluntly triangular ; anterior 

 tibiae sharply tri-dentate ; intermediate and posterior ones with an 

 oblique, punctulate but not bristly carina, hind tibiae very broadly 

 dilated at the apex, the upper spur long, compressed, rounded at 

 apex, the lower sharp ; hind femora short, swollen. The labial palpi, 

 tarsi, and claws are missing in my example. 



The rudimentary structure of the maxillae coupled with the apical 

 insertion of the maxillary palpi would seem to imply that the males 

 of the species included in this genus take no food. In shape it 

 somewhat resembles Cyclomera and Periclitopa, the buccal organs 

 of which are, however, very different. 



Key to the Species. 



Elytra without costules on the elytra, the latter very finely punctured hirsuta. 

 Elytra with costules on the elytra, the latter less finely punctured . . hirticollis. 



Aipeiopsis hirsuta, n. spec. 



Male : Eeddish-brown, with the elytra light chestnut-brown, club 

 of antennae flavescent, frontal part, prothorax, scutellum, and pectus 

 clothed with a very long and very dense fulvous pubescence, 

 pro-pygidium and pygidium with appressed, sub-fiavescent, fine 

 hairs similar to but not so dense as those clothing the sides of the 

 abdomen, femora villose ; elytra with a very short, appressed 

 flavescent pubescence springing from the extremely closely set, fine 

 punctures which impart to the elytra a finely coriaceous appearance ;. 

 frontal part deeply and somewhat widely punctate, almost scro- 

 biculate, straight laterally, bounded in front by a sharp transverse 

 carina, clypeus strongly parabolic in front, very concave, strongly 

 declivous at the basal part, the declivity bounded in the lower
