6l'2 new species of Australian coleoptera, 



posterior declivity rather gradual, nowhere abrupt. Under surface 

 and legs not very densely punctate, punctures distinct. Legs 

 (for the genus) moderately long; tibiae at apex with blackish setfe, 

 the anterior parts beneath with numerous small sharp teeth; 3rd 

 tarsal joint obcordate. Length 8|, rostrum H; width 3 (vi.x) mm.

I have had eight specimens under examination, no two of which" 

 are ex'actly alike; the specimen described above, however, appears 

 to be fairly typical. Some specimens have the prothorax (especially 

 at base and apex) considerably darker than the elytra, the white 

 median line of scales sometimes interrupted in the middle, some- 

 times marked only at the base, and sometimes entirely al)sent;. 

 one specimen has the prothorax almost black except for a sub- 

 lunulate reddish blotch on each side, and the base of the elytra 

 is black; the femora are often tinged with black, as is also the 

 basal segment of the abdomen; one specimen is black, the apical 

 four-fifths of elytra, tarsi and antennte excei)ted. The size varies 

 from 5^ to 9 mm. 



This species is perhaps closest to ferrugineus, l)ut differs in 

 many particulars, the most noticeable being the absence of white 

 rings and the gradual slope and less width of apex of elytra; the 

 rostrum is thicker and less curved. 



It is a curious fact that in this genus the tibiae, tarsi and 

 metasternum much resemble those parts in Syarbis, and the 

 puncturation in many of the species is similar. It is perhaps 

 worthy of remark that in Syarbis, Atelicus and Aonychns, all the 

 species of which are clawless, the tibiae have numerous small 

 teeth beneath; the same is also the case with a clawless species of 

 Erirrhiniilm in my possession. 



Subfamily HYLOBIIDES. 



Having had occasion recentl}' to examine critically a destruc- 

 tive species of Orthorrhinus, and finding that the genus at present 

 is in great confusion, a few remai'ks on the species referred to it 

 may be acceptable.
