590 NEW SPECIES OP AUSTRALIAN COLEOPTERA, 



2nd rather short and thick, 3rd-5th thin, 4th-llth feebly increas- 

 ing in width and subequal in length. Prothorax convex, trans- 

 verse, subquadrate, sides and angles feebly rounded, a feeble 

 transverse impression across middle, more noticeable on sides 

 than on disc; base with a more distinct impression, which is 

 slightly interrupted in middle. Scutellum subtriangular, apex 

 rounded. Elytra not twice the width of prothorax and about 

 thrice its length, not covering pygidium, depressed at basal third; 

 a feeble longitudinal impression near shoulder; shoulders feebly 

 rounded; sides parallel to near apex. Legs thin; femora slightly 

 thickened; anterior tarsi short, four posterior long; 1st joint of 

 four posterior equal in length to all the others. Length 2, width

Hab. — Western Australia: Albany (Mr. R. Helms); Pinjarrah 

 (Lea; beaten from boughs of young gum trees). 



The colouration of this species renders it very distinct. The 

 reddish prothorax gives it a resemblance to hurtiernliis, from 

 which species, however, it differs in many particulars. 



CURCULIONID^. 



Subfamily LEPTOPSIDES. 

 Catasarcus. 



Specimens of this genus are exceedingly abundant in Western 

 Australia; scarcely any collection of Coleoptera from that colony, 

 no matter how small in numbers, but has a number contained in 

 it. In the Transactions of the Entomological Society for 1870, 

 Mr. Pascoe described 34 supposed new species, and at the same 

 time he gave a tabulation of them (including those species 

 previously described) and divided the genus into three sections; 

 it is the second section of that tabulation that I shall now treat 

 of. 



In his general remarks preceding the descriptions of the species, 

 Mr. Pascoe says : — " The sex^oal differences ai^pear to he very 

 slight. The male is a little smaller, and is narrower behind than 

 the female, the elytra curving inwards very perceptibly towards
