Key to the Genera of Endocephalini. 
A. Prosternum produced anteriorly into a cup- 
shaped projection Aemnestus, p. 511. 
B. Prosternum not produced anteriorly. 
a. Antennae with terminal joints broadly flat- 
tened ITeminodes, p. 512 . 
h. Antennae filiform, terminal joints not flat- 
tened Colaspoides, p. 514. 
Genus AEMNESTUS, nov. 
Type, A. fulvitarsis, Jac. 
Range. Assam. 
Body oblong, convex, subcylindrical, glabrous. Eyes oblong ; 
antennae filiform : mandibles of male very prominent and robust. 
Thorax strongly transverse, anterior portion deflexed, sides 
rounded. Scutellum transversely ovate. Elytra not wider at base 
than the thorax, oblong, subcylindrical, lateral lobes not indicated. 
Eemora unarmed, tibiae entire, tarsi short ; claws appendiculate. 
Prosternum distinctly longer than broad, widened anteriorly and 
produced into a round cup-shaped projection, deeply hollowed 
within ; anterior margin of the thoracic episternum slightly 
convex. 
Allied to Colaspoides , but distinguished by the shape of the 
prosternum and the strongly developed mandibles of the male, 
also by the different shape of the thorax.

closely and finely punctured, 
narrowed at apex, surface rather 
at middle of vertex, three 
smooth small spaces between 
the eyes ; clypeus not sepa- 
rated from the face, anterior 
edge perfectly straight ; labrum 
piceous; mandibles very prom- 
inent, broad at base, curved 
at apex ; palpi slender, ful- 
vous ; antennae extending to 
two-thirds the length of the 
elytra, basal joint thickened, 
second small, third and fol- 
lowing joints nearly equal, 
terminal joints scarcely thicker. 
Thorax transversely convex, 
sides strongly rounded, nar- 
rowed in front, surface very 
Elytra subcylindrical, slightly 
more strongly punctured than
