The lower two teeth on the front tibiae are strong but not sharp, 

 the uppermost much less than half as large as the 2nd, the tibial 

 outline straight from its base to the apex of the uppermost tooth. 

 The hind claws are strongly compressed, their basal piece not 

 longer than the apical and having its inner apex sharply produced 

 in a tooth. The erect setre on the upper surface are placed (each 

 on a small tubercle) along the front margin of the prothorax, a 

 very small number on the sides of the disc of the same^ and in 

 TOWS down some of the obsolete costse of the elytra, — especially 

 the 1st, 3rd, and 10th. 



Very like H. normalis, Blackb., but at once distinguished by 

 9-jointed antennae, tuberculated surface, slightly feebler punctura- 

 tion, &c., &c. 



Apparently common in S. Australia. Mr. McDougall of 

 Moonta states that he has seen it " swarming round tea-tree." I 

 have seen examples from Port Lincoln, Yorke's Peninsula, 

 Adelaide, Bordertown, Kangaroo Island. 



H. ELONGATUS, Blanch. 



This insect is so close to the preceding that it will be sufficient 

 to state in what respects the above description must be modified 

 to make it apply to the present species. The form is more elongate, 

 and less dilated behind (long. 6f, lat. 3 J^ lines); there are no rows of 

 setiferous tubercles running down the elytra ; the clypeus is over- 

 topped considerably less widely by the labrum so that the middle 

 lobe of the " trilobed outline " appears to be not more than half 

 as wide as the lateral lobes ; the clypeus and rest of the head more 

 nearly form a continuous even surface, and the sutural margin of 

 each elytron ends in a dense cluster of strong spine-like bristles. 

 A few long setae are to be found on the elytra close to the base. 



[It should be noted that I have examined only a single specimen 

 (9) of this species, which was taken by Sir William Macleay in N. 

 S. Wales, and sent to me by him as H. elongatiis^ Blanch. It agrees 

 very well with Blanchard's description. It is possible that the
