In the male — ;joints 1—3 of the front feet are a little 

 dilated. The doisal plate of the 7th segment of the hind 

 body is produced in the middle, the apex of the produced 

 part a little emarglnate ; on each side of this large middle 

 projection is a much smaller projection. On the under- 

 side the hind margin of the 6th segment is slightly 

 trisinuate ; the 7th segment is a little produced in the 

 middle, and has a deep, rather narroAv notch in the middle. 

 The 8th segment has the lateral lobes moditied and irre- 

 gular, each is corneous, bluntly ])ointed at the extremity, 

 and there furnished with two stout l)lack setre ; before the 

 extremity each is distorted and has an irregular broad 

 projection, which is black at its extremity, the rest of the 

 lobe being pale yellow. The ligula of the a?deagus is com- 

 pressed and keel-like, its hinder half furnished with fine, 

 black, lile-like asperities, it reaches much beyond the body 

 of the organ ; from the latter projects a small fine appen- 

 dage, extending about to the apex of the ligula.

This species is extremely similar to P. hctiis, but it is 

 smaller and has the head a great deal smaller, and the 

 male characters very different. The front tibi;e and tarsi 

 are similarly formed to those of i^. Icetns, but the abdominal 

 characters are very different. The dorsal ])late of the 7th 

 segment has the hind margin simply rounded. The hind 

 margin of the 6th ventral segment is slightly emarginate 

 in the middle, and the ventral plate of tlie 7th segment is 

 distinctly ])roduced, and has a Avell-mai-ked notch in the 

 middle at the extremity. The styles of the 8tli segment 

 are yellow, and are broad at their extremity, which is 

 denselv fringed Avith short, black, file-like seta", and on 

 the under liice of the style there is an additional short 

 series of su<'h seta^ very close to the extremity. 



Ega ; two males.
