282 Mr. F. P. Pascoe on new Genera and Species of 



the apex, nearly impunctate ; scutellum transversely triangu- 

 lar ; elytra rather broader than the prothorax, the sides nearly 

 parallel, striate-punctate, the intervals of the strias flatfish ; 

 body beneath dark glossy brown ; femora and tibise pitchy, 

 tibiae curved, especially the intermediate and posterior. Length 

 4 lines. 



Differs from Ceroprt'a in the antennas, which are scarcely 

 serrated on the inner edge, and in the shortness of the head 

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

 extended geographical range, and there are only two described 

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

 this one an aberrant member. 



Pterohelosus * nitidissimus. 



Pterohelceits strtato-jnmctaius, De Breme, Essai &c. p. 31, pi. 2. fig. 6 (nee

P. ovalis, nitidissime niger ; elytris subtilissime seriatim punctatis. 

 Hah. 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 groove at the base 

 interrupted in the middle ; scutellum curvilinearly 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 ; antennas reaching to the base of the 

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

 h-b\ lines. 



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

 that this is P. striato-punctatius f 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 lsevi ; elytris elongatis, pimctis 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 ponctue." Dr. Boisduval's " striatim " might 

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

 the specific name " striato-jpunctatus" and the French trans- 

 lation " alignes en stries." There are no strias whatever in
