distinctly punctulate with the sides more cocarsely but not con- 

 fluently punctured, the hind angles of the prothorax quite defined 

 but not at all sharp, the elytra not or scarcely striate, with their 

 seriate punctures at least fairly well defined and with a tendency 

 to be non-symmetrical {i.e., not in exact line one behind another), 

 the interstices flat or all but flat. The jDresent species is dis- 

 tinguished from the others by its elytral markings assuming the 

 form of three wide flexuous fascipe which run at right angles to 

 the sutui-e and do not reach the margins. It is also the species 

 of widest form, the elytra being in the male fully as wide as long, 

 and is the most strongly convex, the height of its elytra (viewed 

 from the side) being 4 or nearly so of the length. Its antennae 

 are notably shorter and stouter than in ohJiterata and jndveru- 

 lenta, and the interstices are not quite so flat. The basal joint 

 of the four anterior tarsi of the male is only feebly dilated, with 

 the sides but little rounded. I have not seen, among a good 

 many specimens, any that vary from the type except in the 

 greater or less distinctness of the elytral fascite (none in which 

 they are not quite traceable) and of the infuscation of the seriate 

 elytral punctures. The species occurs in N.S. Wales. 



P. OBLITERATA, Er. 



Differs from the preceding in the markings of the elytra, which 

 consist of («) a blotch running from the humeral callus obliquely 

 hindwards towards the suture, {I) a median fascia not unlike that 

 of l\ minor but narrower and more sinuous and abbreviated at 

 both ends, (c) a subapical mark in the shape of the letter V, 

 (f/')a small dark sutural blotch close to the apex, {e) a small ante- 

 median submarginal blotch. The above marks (or nearly all 

 of them, the subapical V very constant) vary considerably in 

 intensity of colouring. The species is notably less convex than 

 P. minor, with much longer and less robust antennae, the elytra 

 of the male longer (though only slightly) than wide and the 

 elytral interstices more flat. It is common in Tasmania and 

 Victoria, and occurs also in >S. Australia. In rare examples the 

 elytra are almost white and the markings very faint.
