Five basal segments of abdomen rather strongl}^ margined. 

 Length to apex of elytra l^, of abdomen 2 (vix) mm. 



Hab — Beverley, Dai'ling Ranges, W.A. ; Forest Reefs, N.8.W. 



A small dingy species, of which I have seen but a single 

 example from each locality mentioned. The sculpture of the 

 abdomen is invisible under a Coddington lens. The specimen 

 from New South Wales is a little paler and larger than the others. 



Tachyporus vigilans, Oil. — I have numerous specimens from 

 Sydney and Galston agreeing with the description of this species; 

 in the majority of them the antennae (except the three basal 

 joints) are very dark ; in a number, however, they are onl}' 

 slightly infuscate. 



CiLEA RIVULARIS, n.Sp. 



Shining ; brownish-testaceous, basal three joints of antennae 

 and apex of 11th paler, rest of antennae piceous-brown; prothorax 

 sometimes with base and apex paler than rest of surface, some- 

 times this is the case with apex and suture of elytra and apices of 

 abdominal segments; legs pale testaceous. Glabrous. 



Antennie elongate, 10th joint scarcely transverse, 11th the 

 length of two preceding combined, acuminate at apex. Finely 

 punctate, prothorax more sparsely than head; scutellum and base 

 of elytra feebly transversely corrugate or aciculate; abdomen with 

 six projections below and four above on the 6th segment, 5th 

 with six long black hairs at apex beneath. Prothorax strongly 

 transverse, apex feebly emar-ginate, base almost truncate. Elytra 

 scarcely transverse, much longer but scarcely wider than pro- 

 thorax. Basal segments of abdomen finely margined. Length 

 to apex of elytra 1|, of abdomen 2^ mm. 



//«/).— Tweed River, KS.W. 



A small depressed species, numerous specimens of which were 

 obtained at Tumbulgum during a flood in the Tweed Ri\er. 



CiLEA AMABILIS, n.Sp. 



Highly polished; head black, prothorax varying from a clear 

 Ijrown to an almost jet black; all its margins paler, scutellum
