have the antennae slightly longer and the dilated portion 

 of the prothorax less abrupt, but more noticeably thickened ; 

 the basal joints of antennae and legs also vary in colour. 

 I cannot regard these specimens, however, as representing 

 more than a variety of pusillus, and dilataticollis of 

 Blackburn another.

The type of this species is a female and is in the 

 Australian Museum ; a second specimen from Gayndah 

 is in the Macleay Museum and is a male. The type has 

 brownish elytra, becoming paler at the base. Mr. H. J. 

 Carter has taken several specimens at Byron Bay ; these 

 represent varieties having the apical third or fourth of 

 elytra dark, the rest being paler than the prothorax ; a 

 specimen from Wide Bay in the Australian Museum has 

 about half of the apex dark. 



In both series the prothorax is transversely impressed 

 at the base, each side of the impression opening into a 

 fovea of irregular shape and size ; in the description the 

 prothorax is said to have " two small round deep foveae 

 at the base." I certainly, however, cannot regard these 

 foveae as being round (circular) and deep, nor are they 

 isolated as the description implies, each being but a lateral 

 enlargement of the basal impression. 



In build and general appearance (except as to the colour 

 of the elytra) the species strongly resemble gar/aticeps, and 

 the antennae of both sexes and the punctures of the elytra 

 are much the same ; so that it is quite an ordinary 

 Heteromastix.

Tw^o males from Jenolan appear to belong to this 



species ; in one of them the three basal joints of antennae 



are obscurely reddish, in the other the basal one only ; the
