Cubicorrhynchus Mussoni, Blackb., and dilaticeps, 

 Blackb. 

 I think it extremely probable that the types of both' 

 these species are females. On enquiry from Mr. Blackburn 

 he wrote that there was "nothing remarkable about the hind 

 tibiae of either of the species you enquire about." 



Bubaris Hardcastlei, n. sp. 



Black. Rostrum, under surface, and appendages with 

 blackish setae, becoming very short on upper surface. 



Read rough. Rostrum wider than long, separated from 

 head by a deep impression ; with four strongly-punctured 

 ridges and three deep grooves, of which the median one ii 

 continuous and the others deep and wide at base, but narrow 

 and shallow at apex. Scape stout and curved, strongly in- 

 flated at apex; four apical joints of funicle strongly trans- 

 verse. Prothorax moderately transverse, sides strongly 

 rounded ; with large, round, clearly-defined granules and 

 small tubercles, differing only in size. Elytra comparatively 

 short, base not much narrower than prothorax at its widest, 

 sides dilated to beyond the middle ; with rows of very large, 

 irregular punctures, becoming more regular on sides ; with 

 rows of granules varying considerably in size ; base with four 

 strong projections. Abdomen with sparse and comparatively 

 small punctures. Length, 9^-10 mm. 



Hab. — Queensland: Cunnamulla (H. Hardcastle). 



A very wide species with larger granules than usual and 

 without special tubercles crowning the posterior declivity. 



The two specimens before me (and which are probably 

 both females) are practically without clothing other than the 

 setee : but as in some of the depressed places some very short 

 pubescence can be seen, it is probable that on freshly-matured 

 specimens the clothing would be more distinct. The elytral 

 granules are very variable in size. Those on the second inter- 

 stice are larger than any of the others, and many could 

 fairly be regarded as small tubercles ; the fourth interstice 

 has also some large granules. The suture and posterior 

 declivity are both granulate. The larger elytral granules, in- 

 stead of being crowned by a single seta on each, are usually 

 supplied with several, and the setae, instead of being fairly 

 long and suberect, are very short and depressed. Even when 

 there is but one seta (both on prothorax and elytra) that seta 

 arises from a feeble elevation in the middle of a circular 

 depression, crowning the summit of the granule : the depres- 

 sions are always conspicuous, even on the smallest granules. 

 On each elytron there is a rather strong projection on the
