9. Differs in being broader (especially the abdomen), with only 
the base of the antennae testaceous, the head with several very 
shallow indistinct impressions in front. Length to apex of elytra 
of abdomen 3 J; width J mm. 
Hob. — Galston, Sydney, Forest Reefs. 
I can be certain of the sexes of this species, having three pairs 
beaten from the same bush at Galston. 
Helcogastbr ruficornis, n.sp. 
(J. Elongate, flat, shining. Black; elytra piceous black; head, 
except basal half of upper surface, antennae, apex of prothorax, and 
knees, obscure reddish-testaceous. Elytra sparsely pubescent, rest 
of the surface almost glabrous. Almost impunctate. 
Head strongly rounded, transverse; depressed in front; an 
excavation between the eyes, triangularly open behind almost to 
base; seen from in front with four very feeble tubercles; foveas of 
undersurface moderately large; antenna? scarcely reaching inter- 
mediate coxae, equal in thickness throughout. Prothorax decidedly 
transverse, as wide as head, apex truncate; a feeble impression at 
base; middle of apex slightly raised. Elytra not much longer 
than head and prothorax combined, at base wider than head, 
gradually increasing to apex; each feebly separately rounded. 
Basal joint of anterior tarsi moderately large, a curved comb on 
its inner edge. Length to apex of elytra If, of abdomen 2j; 
width J mm. 
Hob. — Sydney. 
I undoubtedly possess females of both this and the following 
species, but cannot satisfy myself as to their identity, as they are 
equally common. The present species differs from the preceding 
in being less parallel, in its differently coloured head and antennas; 
and also by the impressions of the head; from the following it 
differs in the colour of the prothorax, and in its more rounded 
head, with somewhat different impressions. 
Helcogaster canaliculatus, n.sp. 
rj. Elongate, flat, shining. Black, muzzle testaceous; knees 
obscurely brownish-testaceous; antennae obscure testaceous-brown,
