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 

 li, of abdomen 3|; width J mm. 



Hah. — Galston, S3^dney, Forest Reefs. 



I can be certain of the sexes of this species, having three pairs 

 beaten from the same bush at Galston. 



HelcocxASTer ruficornis, n.sp. 



J. Elongate, flat, shining. Black; elytra piceous black; head, 

 except basal half of upper surface, antenna?, apex of prothorax, and 

 knees, obscure reddish-testaceous. Elytra sjDarsel}^ pubescent, rest 

 of the surface almost glabrous. Almost impunctate. 



Head strongly rounded, transverse; depressed in front; an 

 excavation between the eyes, triangularly ojDen behind almost to 

 base; seen from in front with four very feeble tubercles; fovese of 

 undersurface moderately large; antennie scarcely reaching inter- 

 mediate cox*, 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 2|; 

 width I mm. 



Hah. — Sydney. 



I undoubtedl}^ possess females of both this and the following 

 species, ])ut 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 antennse; 

 and also b}^ 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. 



^. Elongate, flat, shining. Black, muzzle testaceous; knees 

 obscurely brownish-testaceous; antennie obscure testaceous-brown.
