Hah. — Queensland: Wide Bay (Macleay Museum), 

 Brisbane (Queensland Museum from H. Hacker). Type, 

 I. 10836. 



A very variable species, of which there are at least two 

 specimens of each colour form described below before me, 

 and of which five forms have been taken in company by Mr. 

 Hacker in October; they all have the basal joints of the 

 antennae pale and the club dark. 



Form 1, d • Black, head and scutellum somewhat paler, 

 claws and front tibial teeth reddish. A specimen of this form 

 has been made the type of the species. 



Form 2, d" • Of a dingy flavous or testaceous, head with 

 base infuscated, prothorax with infuscated blotches, elytra 

 with suture narrowly and sides and apex more or less widely 

 infuscated or black, most of under-surface and of legs black or 

 blackish. The blotches on the prothorax of this form vary 

 from two small and obscure spots to four large longitudinal 

 ones, covering most of the surface ; occasionally the two median 

 ones are conjoined so that there are but three blotches. 



Form 3, d • Head, prothorax, scutellum, and parts of 

 legs more or less brightly flavous (but not shining), elytra and 

 most of under-surface and of legs black. On this form the 

 head is infuscated from the base to the clypeal suture, and 

 there are some vague infuscations on the prothorax. 



Form 4, 9 • Head, prothorax, scutellum, front legs, and 

 parts of the others of a bright flavous, elsewhere black. On 

 this form the elytra are usually of a deep polished black, but 

 on one small specimen parts near the suture are obscurely 

 paler. 



Form 5, 9 • Bright flavous, head and prothorax with 

 vague infuscations, metasternum and parts of middle and of 

 hind legs dark, abdomen partly or entirely pale. One Brisbane 

 specimen has the vague infuscations of the head and prothorax 

 as on this form, but with the elytra obscurely infuscated at 

 the sides, approaching the following one ; another in the 

 Macleay Museum, from Wide Bay, has the upper-surface 

 uniformly pale. 



Form 6, 9 • Bright flavous, head more reddish, elytra 

 with the sides and apex widely infuscated, metasternum, most 

 of abdomen, and parts of legs blackish. The only two speci- 

 mens of this form I have seen are in the Macleay Museum, 

 from Wide Bay, and one of them has the infuscation of the 

 elytra much more extended than on the other. 



It is very difficult to distinguish some males of this species 

 from some males of ruficollis, but the females may be readily
