Genera of Wingless Brachyderine. 5 
points may be added:—Mandibles multisétose, squamose, 
with a distinct median tooth; mentum bare and deeply 
sunk in its cavity. Antenne with the funicle not squamose. 
Gular margin of the prosternum deeply sinuate ;  mes- 
epimeron very small and not separating the mesepisternum 
from the elytron at the base; metasternum at its shortest 
much shorter than the mid-coxe, metepisternal suture com- 
plete, metepisternum not dilated at its base, hind cox 
broadly separated from the elytra. Venter with the inter- 
coxal process truncate and as broad as the hind coxa; hind 
margin of segment | gently arcuate, its length behind the 
coxa greater than that of segment 2, which is longer than 
3 or 4. 
As at present known, the genus-is confined to South-east 
Africa, south of the Limpopo. 
Genus MimavLopes, nov. 
Head deeply constricted behind the eyes and with a central 
furrow which does not reach the vertex ; eyes quite lateral, 
nearly flat and oblique, as seen from above, so that-the head 
is broadest at their projecting hind margins. Rostrum 
about as long as the head and separated from it by a 
straight transverse. furrow, strongly narrowed in front ; 
epistome well defined, nearly three times as broad as long, 
shallowly sinuate in front, and the hind margin forming a 
low curve ; mandibles bearing five or six sete, not squamose, 
with a strong median tooth, the scar flat and almost circular; 
mentum bare, immersed ; scrobes oblique, almost straight 
and parallel-sided, the upper edge touching the lower margin 
of the eye; lower surface of rostrum without longitudinal 
impressions, but shallowly excavated for the reception of the 
antenns. Antenne very short, squamose ; scape reaching 
the middle of the eye, strongly clavate; funicle with joint 1 
much longer and broader than 2, 3-7 very short and 
gradually widening. Prothorax much broader than long, 
the base arcuate in the middle and slightly sinuate at each 
side, the sides rounded. Sceutellum invisible. Elytra fused 
together and strongly inflexed at the sides, only slightly 
broader at the rounded shoulders than the prothorax, the 
longitudinal outline forming & very low curve continuous 
with that of the pronotum, the posterior declivity almost 
vertical. Sternum with the gular margin shallowly sinuate ; 
mesepisternum meeting the elytron only at the extreme 
base, the mid-coxze very narrowly separated ; metasternum 
much shorter than the mid-coxz, its episternum not dilated
