duced near the middle. Elytra parallel-sided or very slightly 
increasing almost to apex, about twice as long as head and 
prothorax combined, in some lights with very feeble traces of 
costae. Apex of penultimate segment triangularly excised. Tibiae 
straight. Length 4 J, width 1 J mm. 
Differs in being less robust, with shorter, thinner and simple 
antennae, and in being dingier in appearance.

Helcogaster foveiceps, n.sp. 
r$\ Depressed, suboblong, shining. Black; head (except sides 
behind the eyes, extreme base, and the middle of the base beneath), 
antennae (except joints 4th-7th), prothorax, apical third of four- 
anterior and tip of posterior tibiae, reddish-testaceous; four- 
posterior tibiae and tarsi piceous, anterior somewhat paler; eyes 
dark brown. Head moderately densely and shallowly punctate, 
prothorax more feebly; elytra, abdomen, and undersurface obso- 
letely punctate. Above with sparse greyish hairs, a few at the 
base of the head, short on prothorax, longest on elytra and sides 
of abdomen; undersurface with moderately long straggling hairs, 
densest on abdominal segments; tibiae moderately densely clothed 
with whitish pubescence. 
Head transversely suboblong; two wide impressions occupying 
most of upper surface, separated in front by an irregular elevation 
(which when looked at from behind appears three-pointed), a fovea 
on each side behind it; eyes moderate, lateral, scarcely prominent; 
antennae scarcely reaching posteriar coxae, inserted almost at apex, 
equidistant at their bases with the middle of the eyes, 1st joint 
scarcely as long as 2nd-3rd combined; 2nd scarcely shorter than 
3rd, 3rd-10th subequal, 11th not as long as 9th-10th combined. 
Prothorax transverse, scarcely as wide as head; apex truncate, 
base rounded, sides widest in front; anterior angles scarcely, 
posterior moderately rounded; median line feebly traceable, a 
transverse impression at base. Scutellum almost concealed by 
prothorax. Elytra about one and a quarter times as long as head
