noticeably diminishing in width to apex; punctures smaller and 

 sparser than in the two preceding species; under surface of 

 apical segment deeply excised in male. Length 4, to apex of 

 elytra 2^ mm. 



Hab. — Richmond River, Dalmorton, N.S.W. 



In general appearance this species approaches to a number of 

 species of Lithocharis, but the remarkable punctures of the head 

 and prothorax are even more clearly defined than in either of the 

 preceding species. The elytral markings are somewhat vaguely 

 defined in places, but in appearance are somewhat like a W or a 

 reversed M with the corners crushed inwards. A female specimen 

 differs in having the head, prothorax and abdomen of an obscure 

 testaceous colour, with the elytral markings absent on the entire 

 basal half. 



Owing in places to irregularity of the punctures, there appear 

 to be a number of small subtubercular elevations on the elytra; 

 in one specimen there are four of these in a straight line down 

 the middle of each elytron, with two others close to the suture, 

 and several near the apex; these small spaces are polished, and 

 from certain directions very conspicuous, but they appear to be 

 solely due to absence of punctures. Similar subtubercular spaces 

 can be traced in most of the other species.

(Plate iv., fig. 3.) 



Narrow and opaque, but with certain parts shining. Piceous- 

 black; abdomen fxiceous-brown, legs testaceous, knees and tibiae 

 darker, antennae testaceous-brown, the terminal joints and the 

 basal half of the 1st paler. Clothed with moderately long 

 brownish pubescence, sparse on head, and still sparser on pro- 

 thorax and elytra.
