 Its depressed form and subopaque surface together with the 

 distinctness of the seriate punctures on its elytra (almost sufficient 

 to place it among the species having these punctures "many 

 times larger than the interstitial punctures ") readily distinguish 

 this insect from P. hrunnea. It is extraordinarily like a species 

 (P. mentitrix) of the aggregate just alluded to, but differs from 

 it both by the much less strong sculpture of its elytra and the 

 extremely blunt (almost rounded) front angles of its prothorax, 

 as well as by an apparently constant difference in the colouring 

 of its head. Its black legs and black margins of prothorax and 

 elytra also distinguish it from hrunnea. I hav-e an example from 

 the Chapuis Collection bearing the MS. name rufohrunnea.

I have not seen an authentic type of these insects, but I feel 

 no doubt they (at any rate the former two) are forms of a single 

 species which is not uncommon in Victoria. The under surface 

 is black, the upper surface varies from a bright brown colour, 

 with the elytra obscurely clouded with piceous, through a form 

 {trivittata) in which the prothorax is blotched with black or 

 blackish and the elytra bear 3 wide black vittse to a form {stygia) 

 in which the whole surface is black, except a spot on the head 

 and sometimes the front margin of the prothorax. Among the 

 species with prothoracic fovese present and elytral puncturation 

 (both seriate and interstitial) fine and about equally so, this 

 species is easily recognisable by the lateral declivous portion of 

 the elytra bearing two or more impressions ;one at least of which 

 is elongate and transverse), the interval between the two principa
