This species is a nieinber of Dr. Chapuis’ “ Groupe IV.” It is a dingy-looking 
insect, having the unusual character of the lateral margin and elytral epipleune 
being (apparently constantly) black. It is also reinarkalile for the middle flattened 
part of its prosternum being rugulose and exceptionally wide. It bears much 
resemblance to P. piLCola, Clip., of which I have an example from Dr. Chapuis’ 
collection, but is readily distinguishable from it by tlie characters just mentioned, 
and also by the somewhat less coarse and rugulo.se sculpture of the surface of its 
elytra. The superficial sexual characters seem almost limited to the tarsi, where 
they are of the kind usual in the genus.

P. convexicollis, Clip. ? (1), Palm Creek. It is impo.ssilile to identify with 
certainty from the descriptions Dr. Chapuis’ species, unless they happen to be 
distinguished by very marked characters. P. convexicollis seems to have been 
taken in Central Australia, and the insect to which I have ventured to apply the 
name agrees with the description, such as it is.
