Prothorax almost as broad as long, (7| x 7 mm.), subconvex, 

 truncate in front and behind, widest about the middle ; anterior 

 angles not advanced ; sides hai'dly rounded, a very little 

 narrowed in front, lightly narrowed to the base ; the lateral 

 margins wide, crenate, not reflexed, not reaching the base ; the 

 base not margined ; the disc transversely striolate ; the median 

 line very faint. Elytra oval (13^ x 8 mm.), convex, smooth 

 (except towards the apex, where the margins are rough), very 

 declivous behind, with the apex rather acuminate ; the peduncle 

 wide, and hardly below the plane of the elytra in the middle ; the 

 sides hardly rounded, but widest in the middle, gently rounded off 

 at the shoulders and obliquely rounded behind ; the lateral margins 

 very fine, not reflexed, a little widened from behind the middle to 

 the apex ; the suture lightly impressed ; each side with three 

 strong marginal punctures near the shoulders, and three others at 

 the beginning of the roughened apical portion of the elytra ; 

 scutellum lunulate behind. Anterior thighs long, flattened ; the 

 tibise with a small dentiform projection on the outer edge opposite 

 the upper internal spur, dilatate at the apex, and externally ending 

 in a dentiform projection, internally with a small sharp tooth just 

 above the long apical one ; middle tibiae with two acute spines 

 internally, apex widened, and acutely pointed externally ; tro- 

 chanters very short and wide behind. The ventral segments, 

 except the last, longitudinally rugulose near the sides, impunc-

This fine species is very distinct from all those previously 

 described. I am indebted for my single specimen to Mr C. 

 French, Government Entomologist of Victoria, to whom I dedicate 

 the species. 



The following is a list of the authors whose papers contain all 

 necessary references to the genera and species treated of in this 

 paper.
