This species is in appearance exactly like the preceding 

 one, but differs by the abdominal characters of the male, 

 and also by those one or two ])oints, ■which may ])erhaps 

 be individual I'ather than speciiic. The antcnnje have the 

 third joint a little longer, so that it is slightly longer than 

 the 2nd, and joints 4 — 11 are a little more dusky. The 

 elytra are rather more closely and finely punctured. 



In the male the middle part of the ventral plate is a 

 little produced backwards and has at its extremity a narrow 

 but rather deep triangular notch. The head is broader 

 than the thorax. 



In the female the head is only as broad as the thorax, 

 and the fi-ont femora are unarmed. 



Ega ; two specimens, ^ , $ . 



Ohs. — Besides the specimens above described, there arc 

 four others from Ega and Tapajos (one ^ and three 9 ), 

 about which I cannot feel sure whether they belong to 

 P. cognatus or an extremely closely allied but distinct 

 species.
