suture near apex feebly depressed. Feaiora (especially anterior) 

 thick; tibia; straight, longer than tarsi, a minute sj^ine at their 

 apices. 



The female differs in being much narrower across the shoulders 

 than the male, being there no wider than the prothorax at base; 

 elytra shorter, less parallel-sided, more feebly depressed at the 

 base and less hairy. Length 2J, width | mm. 



The above species diflfers from F. Clarki, King, in being smaller 

 and narrower, much hairier, less strongly punctured, with a 

 differently shaped pi'othorax, kc.

I ha^•e carefully compared the types of F. humeralis, Macl., 

 with the above species and find them identical; the colour of the 

 prothorax ranges from red to black; the elytral macuU« are 

 apparently never united; the size is constant. I have it from a 

 number of j)laces in New South Wales, but it is not very common. 

 There are also specimens from N.W. Australia in the Macleay 

 Museum. 



F. Clarki, King; Masters' Cat. Sp. No. 4250. 



It appears to me that A. char on, King, is the male of this 

 species, the sexes of which differ as F. vUlosipennis (?). They are 

 certainly congeneric, and if distinct are very closely allied species. 



TOMODBRUS BRBVICORNIS, n.sp. 



Elongate, parallel-sided, depressed, shining. With the excep- 

 tion of the eyes (which are black) testaceous, legs paler. Clothed 

 above and below with rather dense pale pubescence (densest on 

 the elytra). Head at the sides sparsely punctate, glabrous in the 

 middle; prothorax minutely punctftte at sides and base; elytra 

 strongly punctate on basal half, more feebly towards apex, the 

 punctures in rows; lower surface minutely punctate. 



Head rounded, slightly transverse; eyes small, prominent, 

 coarsely faceted; antennae thickening towards apex, reaching
