526 REVISION OF THE GEXERA COLPOCHILA, ETC. 



above), the elytra more strongly punctured, with their sutural 

 apex briefly spined, &c., &c. The uppermost of the three teeth on 

 the front tibife in this species is very small as compared with 

 most other Colpochilne. Two female examples in my collection 

 appear to belong to this species, although differing much iu 

 colour. Their elytra are of a rich iridescent blue colour, and 

 their underside is piceous, as also their antennae and legs, but I 

 can find no other difference. 



S. Australia ; Adelaide district. 



N.B. — A male example taken in the Port Lincoln district (the 

 only iridescent Golpochila 1 have seen from that locality) has the 

 antennae pale testaceous in contrast with the dark brown head (in 

 C. bella from the Adelaide district the antennse ai-e always of the 

 colour of the head), the basal joint of the antennal flabellum 

 decidedly less than half as long as the 2nd joint, the scutellum 

 wider and more rounded behind, the. elytra a little less strongly 

 punctured, and the general form wider and shorter. I think it is 

 probably best regarded as a local form of C. bella, which might 

 perhaps be distinguished as " var. ? Lindensis."
