602 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Beneath shining and minutely punctate; abdominal segments 

 irregularly depressed at the sides, the penultimate not incised. 

 Length 1 3, width 5 mm. 



Hah. — Armidale (Mr. D. McDonald). 



This species seems to me to come closer to Trichalus than 

 Met*orhynchus, having the first elytral costa divided into three. 



Trichalus distinctus, n.sp. 



(J. Black; reflexed margins of prothorax and elytra red, the 

 elytra close to the scutellum, and the disk posteriorly tinged with 

 black. Head, disk, prothorax, scutellum, and lower surface 

 shining. 



Rostrum short; antenntt reaching to beyond the middle of the 

 •elytra, 2nd-9th joints subequal in length, their bases gi'adually 

 diminishing in width, 10th one and a half times as long as 9th. 

 Prothorax barely transverse, trisinuate at base, the posterior 

 angles produced; a deep lanceolate impression in the middle, 

 joined to the apex by a short carina; irregularly punctate at sides 

 and apex. Scutellum depressed in the middle, the apex very 

 slightly emarginate, with the angles rounded. Elytra very 

 slightly widened posteriorly; punctui-es large, transversely oblong; 

 suture and lateral margins thickened; 2nd, 4th and 6th interstices 

 very slightly different from the others, the first divided into three, 

 the middle one not much more prominent than the others, being 

 slightly thickened at the base, it and the outer one continuous to 

 base of the elytra, the inner one continuous to the scutellum. 

 Beneath minutely punctate; metasternum sulcate along the 

 middle; abdominal segments irregularly depressed at the sides, 

 the penultimate sharply, but not deeply, incised. Length 14, 

 width 4^ mm. 



Hab. — Galston. 



I have described the foregoing species as having ten-jointed 

 antennae, not mentioning the true second joint, but in this sj^ecies 

 it is very noticeable, not being entirel}' overlapped by the first, 

 and having the apex red.
