about ^ the size of the basal piece and nearly twice as large as the 

 produced apex (which is truncate at its end) of the latter. There 

 is a conspicuous fuscous spot on the prothorax near the lateral 

 margin on either side. 



This is an extremely distinct species. 



Yorke's Peninsula. 



N.B. — This species must be near H. j^ellucidus, Burm., but if 

 I am right in thinking that I have both sexes before me, the 

 anterior claws of the male are quite different ; also the anterior 

 tibiae seem to be differently toothed ; it seems unlikely that Dr 

 Burmeister could have failed to note the very peculiar angulation 

 of the labrum, or the spots (apparently quite constant) on the 

 prothorax. The description of the puncturation also does not 

 agree very satisfactorily.

Minus elongatus ; postice dilatatus ; sat nitidus ; ferruginous,

The labrum rises so slightly above the clypeus and the sides of 

 the latter are so feebly reflex ed that (from the point of view most 

 favourable for observing a " trilobed outline " of the head) the 

 front outline appears an almost even curve, the convexity of which 

 however is a little greater in the middle than it would be if the 

 curve were quite even. The clypeus does not form an even surface 

 with the rest of the head, — from which it is separated by an 

 almost straight suture; its front is scarcely concave, but is without 

 a reflexed margin. The prothorax is about f again as wide as it 

 is long ; its base about half again as wide as its front, which is 

 feebly concave with angles but little produced ; it is widest a little 

 behind the middle its sides being rather strongly arched, its basal
