At first sight apparently belonging to luridus, but on examina- 

 tion seen to be very distinct. Of the species described by Dr. 

 Sharp it appears to most nearly approach siijnatus, except in size. 



B. Wing-cdses destitute of a distinct sutural stria. 



BiDESSUS PICTIPES, n.sp. 



Rather widely ovate ; shining ; with very fine pubescence. 

 Piceous: head, antennas and prothorax testaceous-red; sterna and 

 abdomen reddish-piceous; legs testaceous, apex of tibise and parts 

 of tarsi piceous. 



Lateral stri» of prothorax slightly curved, almost as long as on 

 elytra ; elytra rather densely and strongly punctate. Length 

 li (vix) mm. 



Hnb. — Pinjarrah, W.A. 



The smallest species of group B. It is scarcely as long as 

 fasmlineatus but is wider. 



BiDESSUS BLEGANS, n.sp. 



Subopaque, depressed; with veiy fine pubescence. Reddish- 

 testaceous, elytra infuscate. In certain lights with a pretty 

 bluish iridescence. 



Lateral strise of prothorax curved, more than half the length of 

 prothorax itself and fully as long as on elytra. Elytra densely 

 and finely punctate. Length 2^ mm, 



//a5.— Beverley, W.A. 



On several specimens there is a slight duskiness about the base 

 of head and middle of prothorax. The species superficially 

 strongly resembles mundus, but the pallid under surface and 

 curved prothoracic strife should prevent the two from being 

 confused. 



BiDESSUS pr.i:largus, n.sp. 



^. Shining, glabrous. Piceousbrown ; prothorax reddish- 

 testaceous, the base infuscate; under surface and legs reddish- 

 testaceous.
