decidedly longer than, and not at all more than half as wide as, 

 the lateral lobes. The longitudinal series of setiferous granules 

 on the elytra, so marked a cliaracter in H, inhstulosiis^ are quite 

 wanting here, and the general form is less robust, scarcely dilated 

 behind, legs more slender, external teeth of the front tibiae a little 

 sharper, prothorax narrower in front, puncturation less fine and 

 close. 



A dark red specimen in my collection (locality uncertain) seems 

 to be this species, but it is too much broken for certain identifica- 

 tion. I suspect most of the species of this group vary in colour. 



S. Australia ; Adelaide district, Kangaroo Island, &c. 



N.B. — Among a large number of specimens of this insect 

 examined by me I have found one example belonging to Sir 

 William Macleay which has some feeble indications of pustules 

 down the elytra close to the suture. I have not seen any 

 example of II. pustulosus in which the pustules are not quite 

 well defined there and in other rows on the elytra. The two 

 species are very distinct by several other characters, and I think 

 the example of rhinastus bearing the pustules must be regarded as 

 quite abnormal.

Nearest to H. rhinastus^ I think, but differing widely by the 

 much closer puncturation of the elytra which do not appear
