 pecularities, and it is consequently elevated to generic rank.

 FEMALE 

 Head as seen from in front hardly wider than long, not so 

 thick anteroposteriorly as in P. terryi; frontovertex about one- 

 half longer than wide ; ocelli in an equilateral triangle, the pos- 

 terior pair about one-fourth their own diameter from the eye- 

 margin, the median one at the center of the frontovertex ; eyes 

 large, not pubescent, in outline nearly circular except for the 

 dorsal orbits being parallel ; cheeks moderately long, or about 

 four-fifths as long as the diameter of the eyes ; antennal scrobes 

 moderately deep, meeting above in an acute angle ; mandibles

tennal scape (fig. 4, A) flattened and expanded below, nearly 

 one-half as wide as long ; pedicel about as long as the first three 

 funicle joints combined ; the funicle increasing gradually in 

 width so that the sixth joint is a trifle more than one-half wider 

 than the first, the first three, and especially the second, shorter 

 than the last three joints, all increasingly wider than long ; club 

 large, oval, rounded at apex, a little longer than the last three 

 funicle joints combined, and after collapsing one-third as wide 

 again as the last funicle joint. Wings thickly ciliated, the cilia
