sciTatcd on the inner edge, and in the sliortness of the head 

 anteriorly, the eyes nearly free, &c. As the genus has a very 

 extended gcograjiliical range, and there are only two described 

 species from Australia, it seems best for the present to consider 

 this one an aberrant member. 



Pterohelams * n ifidissh/uis. 



Pterohelceus sfriafo-pmidaius, DeBreme, Essai &c. p. ol, pi. 2. fig. C (ncc 

 Boisduval). 



P. ovalis, nitidissime iiiger ; clytris subtilissime seriatim punctatis. 

 Hab. South Australia. 



Oval, moderately convex, very glossy deep black ; head 

 finely and closely punctured, clypeal groove broad and shal- 

 low ; prothorax very minutely and rather closely punctured, 

 rounded at the sides, the edge of the expanded margin ante- 

 riorly recurved, an irregular well-marked groovg at the base 

 interrupted in the middle ; scutellum eurvilinearly triangular ; 

 elytra a little contracted behind the shoulders, very finely 

 seriate-punctate, the punctures less regularly arranged near 

 the suture ; body beneath and legs very glossy black, pro- 

 pectus opaque, granulate; antennai reaching to the base of the 

 jjrothorax, third joint half as long again as the fourth. Length 

 5-5^ lines. 



A typical specimen, I believe, in the Oxford Museum shows 

 that this is P. striato-j^unctafuSy De Breme ; and his description, 

 with one exception, fairly enough accords with it ; I hold, 

 however, that it cannot be the same species as that described (?) 

 by Dr. Boisduval in the following words : — " Elongato-ovata 

 nigra ; thorace laevi ; elytris elongatis, punctis majoribus im- 

 pressis striatim digestis"t. The exception alluded to is the 

 phrase '' fortement ponctue," which may be a slip of the pen 

 for '' faiblement ponctu(3." Dr. Boisduval's '' striatim " might 

 in the same way have been intended for ^^ seriatim," but for 

 the specific name '"'' striato-jmnctatus'''' and the French trans- 

 lation " alignds en stries." There are no stride whatever in 

 the species before us, nor are there any mentioned by M. de 

 Breme. 



Pterohelceus vicarms. 



P. sat late ovalis, fusco-niger, nitidus ; sulco clypeali distincto ; 

 clytris leviter seriatim punctatis. 



Hab. Queensland ; New South Wales ; Victoria.
