 each elytron is rounded. The femora are more or less pitchy, 

 tiie tibiae almost entirely so, the tarsi rather j)aler.

Hah. Ecuador, Porvenir, March 1899 {P. 0. Simons). 



This species has the jet-black colour of F. BucJcIeyi and 

 P. iphi's, but differs from both these in having the elytra 

 separately rounded at the apex, as in P. cacicus &c. It 

 differs from P. cacicus, atys, Simonsi, and Giintheri in 

 having the sculpture of the elytra almost uniform throughout, 

 as in P. Biicklej/i, and the apices are not flattened. The 

 head is very coarsely and closely rugose. The mandibles as 

 long as the head, falcate. The tubercle behind the eyes is 

 thicker and larger and more obtuse at its apex than in any 

 other species known to me. The thorax is vermiculate- 

 rugose, almost as in the elytra ; the sides have three nearly 

 equidistant acute teeth, the anterior one much smaller and 

 less prominent. The elytra are rather more than a third 

 longer than broad (19x 26 millim.), uniformly vermiculate- 

 rugulose, as in P. Jhickhyi; the sides gently arcuate (not 

 rectilinear in any part). The antennai are black and reach 

 rather beyond the apex of the elytra.
