Gamka minuta, n. spec. 



Male : Head, pro-thorax, and under side reddish-brown, elytra pale 

 testaceous, almost stramineous, with the suture narrowly infuscate ; 

 antennae dark chestnut ; labrum nearly half the width and half the 

 length of the clypeus, margins of the latter plainly raised, the 

 anterior one transverse, surface deeply pitted, that of the head also 

 deeply pitted and bearing scattered, upright, flavescent hairs, 

 clypeal keel sharp, vertex simple ; antennal club of male longer 

 than the head, labrum included, 7-jointed, but the inner joint 

 is formed by the laminate elongation of the inner basal part of the 

 fourth antennal joint, the remainder of this particular joint being 

 compressed and looking as if supporting the base of the fan when 

 the latter is folded or partially spread ; prothorax slightly convex in 

 the posterior part, rounded and ampliate laterally in the middle, with 

 the basal angles rounded but with the apical ones sharp, and having 

 a lateral fringe of long, bristle-like hairs, it is deeply and somewhat 

 roughly punctate, the punctures being separated in the median part 

 by an interval equal to their diameter ; scutellum brownish, ogival, 

 impressed at the base ; elytra parallel, not much convex except in 

 the apical part where they project beyond the strongly drawn-in 

 pygidium, very faintly bi-costulate on each side near the suture, 

 coarsely punctate, and with a lateral marginal fringe of equi-distant 

 hairs extending to two-thirds of the length ; margin of the punctate 

 pygidium with a fringe of long hairs ; pectus only moderately densely 

 hairy ; upper margin of intermediate and posterior tibiae with two 

 angular, bristly projections not continued as oblique ridges on the 

 outer face of the tibia. 



Length 5-J- mm. ; width 2^- mm.

AIPEIOPSIS, n. gen. 



Mentum more than twice as long as broad, straight laterally, but 

 tapering a little towards the apical part which is narrowed, truncated 

 at the tip, nearly as broad as long, and divided from the mentum by 

 a plainly triangular suture ; labial palpi set in the outer face, joints 

 thick, the two basal ones short, contiguous, apical one massive, sub- 

 fusiform outwardly, nearly straight inwardly, not acuminate at tip ; 

 maxillae long, straight, somewhat dilated towards the apex, and with the 

 maxillary palpi inserted on the top, on a level with the obtuse, nearly 

 obliterated, slightly hairy upper lobe, inner lobe also obliterated but 

 ciliate ; mandibles very long, slender, sharp at the tip ; head plane, 

 separated by a high transverse carina from the clypeus which is
