Size small. Wingless, or wings scale-like. Head moderately

ium nearly twice as wide as first antennal joint, vertex de- 
pressed, carinate. Pronotum equally as wide in front as behind, 
lobes rounded. Eyes small, elliptical. Hind femora with very 
small spinelets. Fore tibiz below with five spines on each side. 
Hind tibie flattened, spinelets very minute. Abdomen of male 
with ninth dorsal segment rather short; supra-anal and sub- 
genital lamine prominent, latter narrow, acutely triangular, 
deeply cleft. Styles distinct. 
The following synopsis will indicate the place in the system 
occupied by this genus :— 
4.4. Body wingless, or lobes quite rudimentary. Head 
broader than pronotum. Occiput elevated. 
5. Size large. Head much wider than pronotum. 
Fastigium very broad, subrotundate. Fore tibiz 
below with three to four spines on each side. 
Abdomen of male with ninth dorsal segment 
produced, hood-like. Apotrechus. 
5.5. Size small. Head not much wider than pro- 
notum. Fastigium rather narrow, depressed in 
front, keeled. Fore tibie below with five pairs 
of spines. Abdomen of male with ninth dorsal 
segment short, not hood-like. Apteronomus.

Clypeus trapezoidal, quadrangular, narrower below, as wide above 
as high. Labrum elongate-oval, ferruginous. Fastigium of 
vertex narrow, widely separated from the antenne, margins 
angular, parallel, scarcely keeled, without lateral pale marks, 
apex semicircular, dark-brown. Antenne concolorous, three 
times the length of body. Pronotum rounded above, shiningly 
smooth, fore margin convex and raised, hind margin concave ; 
lobes nearly as high as long, angles much rounded, margins 
narrowly incurved. Hind femora below with five internal and 
two to four external minute spinelets. Hind tibie flattened 
above, with five internal and four to five external spinelets. All 
the legs (also the antennz) closely covered with short tomentum. 
Subgenital lamina of male narrowly triangular, deeply cleft,
