except the sublateral fovea on either side, its base with a very- 

 narrow pseudo -margin (as indicated above under picipennis, 

 Hope), the sides not sinuate in front of the middle and not 

 stronorly sinuate behind the middle ; the eyes nitid and smooth 

 (but with underlying granulation visible in some examples) ; 

 elytra very finely crenulate-striate, stride somewhat nitid, crenu- 

 lations very feeble and not wider than the stride, interstices flat 

 (or nearly so) scarcely puactulate, pygidium and metasternum 

 8carcely punctulate ; front of clypeus just perceptibly sinuous in 

 the middle; no sexual distinctions observed (although numerous 

 specimens examined) except that in some examples the front 

 tibise are more slender than in others. The only discrepancy with 

 Hope's description is in the colour of the antennal club. Hope 

 calls the antennae of the type " piceous " in distinction from the 

 general black colour. In reality the club of the antennae is dull 

 testaceous, but in several specimens before me (and probably it 

 was the case with the type) the club is dirty and looks darker 

 than it really is. 



0. australis, Guer. ^ I am doubtful as to whether the common 

 Onthophagus that usually bears this name in collections is really 

 this almost undescribed insect. The original description is prac- 

 tically unintelligible unless assisted by comparison with the 

 Indian 0. dama, Fab., but as its author expressly states that its 

 elytra are black and the elytra of the Onthophagus I refer to are 

 always more or less green or coppery, there certainly seems to be 

 a doubt about the identification. Harold published a note in 

 1867 claiming the name for the common Onthophagus to which it 

 is usually attributed, but he gives no reason for his determina- 

 tion, which could not possibly be decisive of the matter unless it 

 was founded on comparison with the type. As, however, 1 have 

 no means of ascertaining whether the type is still in existence, 

 I accept Harold's identification; though it is to be noted that 

 Guerin says of australis " thorace mutico " which does not apply 

 (as Harold himself indicates) to the species for which he claims 

 the name.
