 stria-, which is just before the break. The interspaces are flattened, as in 

 I', destitutus, and the intimate structure of their surface is exactly as then-. 

 except in showing scarcely any sign of reticulation.

A couple of elytra, from each of which the entire apex is broken, 

 closely resemble P. patruelis Dej in shape and sculpture, but represent a 

 species a little larger than it. The sutural stria is exactly as in that species, 

 and the stria 1 are linelv impressed and without punctures; the interspaces 

 would appear to be flatter than in P. patruelis, and the third interspace do, -^ 

 not appear to have the three punctures found in that species, but onlv the 

 central one. Tin- color is blackish castaneous.
