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



ticketed, as Prof. Westwood informs me ; so that they had 

 afterwards to be determined by these descriptions. As the 

 vast collection of Mr. Hope was at his death in some disorder, 

 it is not impossible that in some instances the true types may 

 have been overlooked. 



Cestrinus aversus. 



C. elongatus, subdepressus, fuscus, subnitidus, subtiHter sparse 

 griseo-pubescens ; eljtris striato-punctatis, obovatis. 



Hah. Tasmania. 



Elongate, subdepressed, dark brown, slightly nitid, finely 

 and remotely pubescent, the pubescence composed of very 

 small stiff greyish bristles ; head closely punctured, clypeus 

 separated from the front by a slightly arched, deeply impressed 

 groove ; prothorax a little broader than long, closely punc- 

 tured, widely emarginate at the apex, the sides slightly rounded 

 and obsoletely crenated, the base truncate ; scutellum small, 

 transverse ; elytra broader than the prothorax at the base, the 

 greatest breadth towards the apex, striate-punctate, the punc- 

 tures approximate and deeply imj)ressed ; body beneath and 

 femora pitchy brown, finely punctured, tibise paler ; antennae 

 and tarsi ferruginous. Length 3 lines. 



Cestrinus piinctatissimus. 



C. elongatus, subdepressus, rufo-fuscus, opacus, subtiliter griseo- 

 pubescens ; elytris striatis, creberrime punctatis, lateribus paral- 

 lelis. 



Hah. Tasmania. 



Elongate, subdepressed, reddish brown, opaque, with scat- 

 tered greyish bristles ; head and prothorax as in the last ; 

 scutellum curvilinearly triangular ; elytra broader than the 

 prothorax, the sides nearly parallel, striated, each of the sti-iag 

 filled with two or three rows of closely impressed irregular 

 punctures ; body beneath, legs, and antennae pale reddish fer- 

 ruginous, the former and femora punctui'ed. Length 3 lines. 



The closely arranged punctures on the elytra, many of them 

 impinging on the lines between the strife, will readily distin- 

 guish this species from the former, 



Cestrinus posticus. 



C. elongatus, fuscus, subtiliter sparse griseo-pubescens; elytris 

 striato-punctatis, apicem versus elovatis. 



Hah. Tasmania. 



Elongate, subdepressed, dark brown, with scattered greyish 

 bristles ; head and prothorax as in C. averstis, but narroAver, 

 and the jmuctures smaller ; scutellum confounded with the
