60 Major Parry’s Catalogue 
A single ¢ specimen of this interesting new species was re- 
ceived from Sarawak, Borneo, and is provisionally placed with 
the genus Zeus, differing, however, in the short convex character 
of the elytra, and more especially in the singular trilobate lateral 
margins of the prothorax. A knowledge of the other sex of this 
species might possibly throw some light as to whether it might be 
regarded as the type of a new genus.

Readily distinguished from its European ally, P. Caraboides, 
by its narrower and more convex form, its prominent and more 
slender mandibles, its impressed and sparsely punctate head, the 
sinuate lateral margins of the prothorax, the obtuse posterior 
angles and punctuation of that segment, and, finally, by its more 
parallel and sparsely punctate elytra, the interstices being smooth.
