DD. Punctures in nrothorax too crowded 

 to be inddvi'dually distinct, except 

 occasionally about apex. 

 E. "With a costiform elevation behind 



each shoulder pidcherrimo 



EE. Without such. 



F. Transverse impression of pro- 

 thorax feeble. 

 s. Median line of prothorax distinct 



when viewed obliquely cun}ou-i 



ss. Median line not traceable ... similis 

 FF. Transverse impression distinct 



G. Size above average liistrihuta 



GG. Size decidedly small. 



H. Unusually narrow, with longer 

 antennae and legs than 



usual (inicUicornis 



HH. Not as H aurea

A. On apicicolli.^ the prothorax is not transversely 

 impressed, but towards the base the punctures are more 

 crowded than elsewhere, and it is possible that on some speci- 

 mens a vague depression would be visible. If placed in A A 

 it would fall beside rillom, whose prothoracic impressions are- 

 very different. 



A A. The impression is sometimes very feeble, but usually^ 

 may be clearly seen, on account of the punctures there being 

 denser than elsewhere ; it is seen most clearly from an oblique 

 direction; on several species (including insir/nis, one of the 

 most distinct of the genus) the impression, although not dis- 

 tinct in the actual centre of the disc, is represented by a 

 distinct remnant each side of same. 



h. Soror might have been referred to the group with 

 elytral pubescence entirely short, but as on each of the thirteen 

 specimens before me a few upright hairs are to be seen it has 

 been placed here. 



TOMYRIS PUSILLA, Lef. 



The description of this species is extremely short, and' 

 would appl}^ to the females of many species of the genus: but 

 in the late Rev. T. Blackburn's collection there was a specimen 

 from Perth so identified. I have taken the same species at 

 the Swan River, Bridgetown, and Pinjarrah, but all these are 

 larger (2^-3 mm.) than the type (2 mm.). I doubt if it is 

 more than a western representative of viridula, and like that 

 species the legs of its females (the only sex known ^^2)) are- 



(62) On one card before me a small green male is mounted 

 with a female, but not marked as having been taken in cop. It 

 differs from the male or viridiiJa in being smaller, transverse' 

 impression of proth.orax more distinct, an interrupted ridge in 

 front of same ; and punctures considerably larger.
