a small spot on either side close to the margin on each of the basal 

 four segments. The metasternum is roundl) convex as in 

 H. fuscipes ; the meso- and pro-sterna are acutely carinate as in 

 H. ohlongus, Hbst., moderately long cilia springing from each 

 carina. The general form is longer and more parallel than in 

 H.fusci2:)es, with the anterior angles of the prothorax less defined. 



A variable insect. The following is, so far as I have seen, about 

 the extreme of its variety : — a little smaller thar the type ; color 

 a deeper black ; no red markings on the underside ; the punctura- 

 tion throughout a little less close ; the rows of punctures better 

 defined, all being clearly traceable to the base ; the interstices 

 quite strongly convex in their posterior third part. It is possible 

 this may be a good species. 



Common in South Australia.

The description of H. Australis might be read to apply to this 

 species in all respects except color and shape, the sculpture of the 

 segments presenting no noticeable difference. It is, however, a 

 notably narrower, luore convex, and more parallel insect, with 

 elytra very little less than twice as long as together they are wide, 

 while those of Aicstrcdis ai'e scarcely half again as long as wide. 



A single specimen in my collection, from Victoria; exact locality 

 not known.
