polished groove in which portion of the tibia can rest, the 

 groove bounded on one side by a feeble ridge. 



A brassy male, compared with the type of setosa, and sent 

 for examination by Mr. Arrow, agrees perfectly in all struc- 

 tural details with several males that I refer to aureoviridis. 



Edusa pavens, Blackb. 



Of this species only the type (a female) was previously 

 known. It was described as having "femoribus anticis late 

 angulatis vix dentatis,'' and so tabled. There are before me 

 numerous specimens from Western Australia (Donnybrook, 

 Geraldton, Mount Barker, Swan and Warren Rivers) that 

 probably belong to the species. From certain directions their 

 front femora appear to be evenly rounded, from others rather 

 widely angulate, but from others a small and quite distinct 

 tooth is visible. The male differs from the female in being 

 decidedly smaller (2 mm. only), green or golden-green, and on 

 the under-surface somewhat brassy-green. The legs are 

 stouter, fifth abdominal segment vv^ith a small median fovea 

 (with a shining central space), and the longer hairs on the 

 elytra less conspicuous. 



Edusa diversicollis, Blackb. 

 PL vii., fig. 64. 



A female of this species in the Macleay Museum is labelled 

 as from Sydney, C^^) and is rather more uniformly golden-red 

 than is usual ; the species is readily distinguished by its un- 

 armed front angles of prothorax and elongate form. 



Edusa froggatti, Blackb. 



Apparently this species was described from a unique 

 female, ^^4) whose colour was stated to be almost as in 

 chrysuraX'^) Its impunctate scutellum was relied upon as its 

 most striking feature. I have seen no specimen of the larger 

 pubescent species with the scutellum altogether without punc- 

 tures ; but a female of spinicollis C^^) before me has three small 

 ones only ; it was taken in cop. with a male whose scutellum 

 has about a dozen. Both these specimens have the elytral 



(73) The locality needs confirmation. 



(74) The type is now in the British Museum; in Blackburn's 

 collection it was represented by a label only. 



(75) One of the most variable species of the genus. Specimens 

 in the Museum are green, golden-green, golden-red, blue, purple, 

 brassy and bronze, and with many intermediate shades or com- 

 binations of shades. 



(76) Quite as variable a species as chrysura, and abundant on 

 many parts of the Blue Mountains.
