the fi'ont margin of the eyes is suggestive of some species {eg., 

 subapicalis, Chp.) of subgroup iv., but I do not think they would 

 be suitably placed among that aggregate. The present species is 

 very distinct from its allies by its very much greater convexity 

 and from circinndata by the much more widely spaced (and 

 towards the apex obsolete) punctures of its elytral series. The 

 basal joint of the 4 anterior tarsi in the male is elongate but not 

 strongly dilated. I have seen some examples from N.S. Wales 

 which seem scarcely so convex as the type and have the prothorax 

 and elytra a trifle more widely margined with testaceous and also 

 the front of the former testaceous, but I take them to be mere 

 varieties.

P. ciRCUMDATA, Newm. 



The desci'iption of P. rii/ipes, Fab., fits this species very well, 

 and if it be founded on the same insect as Newman's name 

 rujipesis much the older name; but as the habitat of the latter is 

 given " South Sea Islands," it is perhaps safer not to assume 

 identity and to omit rufipes from the Australian fauna until 

 further evidence is forthcoming. The species is common in 

 Victoria and Tasmania.

P. IRINA, Chp. 



This species is so strongly characterised by its evident viola- 

 ceous submetallic tone of colour together with its unusual 

 (elongate-oval) form and the large fovea-like impressions of its 

 elytral series that I cannot feel any doubt about my identification 

 of it in spite of my examples having come from "Victoria, while 

 Chapuis gives Northern Queensland as its locality. The basal 

 joint of the 4 anterior tarsi in the male is strongly dilated, but 

 I do not find other well marked sexual characters. 



P. ocTOMACULATA, Marsh. 



This appears to me to be the most variable species in the genus 

 both in respect of size and colouring. Its distinctive characters
