GAMKA MINUTA, N. spec. 
Male: Head, prothorax, and under side reddish-brown, elytra pale 
testaceous, almost stramineous, with the suture narrowly infuscate ; 
antennz 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 tibiz with two 
angular, bristly projections not continued as oblique ridges on the 
outer face of the tibia. 
Length 54 mm.; width 24 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 ; 
maxillz long, straight, somewhat dilated towards the apex, and with the 
maxillary palpi inserted on the top, on a level with the obtuse, nearly 
obliterated, slghtly 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
