9 Black, similar to P. scelestus in nearly all respects; in hind tarsi the 

 fourth joint is a little longer than in P. scelestus, being nearly equal to the fifth; 

 in the fore wings the basal vein is plainly a little before the transverse. The 

 anterior tarsus has the comb of very much shorter spines than in P. scelestus, 

 the two on the second joint hardly half as long as those in P. scelestus; there 

 are four short ones on the first joint, all these spines are rather stout and a 

 trifle curved. 



Length 11 mm.

9 Black, densely long haired; clj^peus broad, truncate in front, slightly 

 margined; first joint of antennae with hair beneath, third joint quite long, 

 second and third together equal to vertex width, groove above antennae to 

 anterior ocellus, hind ocelli about as close to eyes as to each other, vertex from 

 in front straight across; pronotum angulate behind; metanotum with a median 

 groove, not very deep; legs moderately long, not very spiny, hind tibiae with 

 only about four above, inner spur of hind tibia reaches little beyond middle of 

 the basitarsus, three spines in comb of the first tarsal joint, the last not equal 

 to next joint. Wings violaceous black, marginal cell hardly its length from 

 wing tip, second and third submarginal cell subequal, both broad above, 

 second recurrent reaching cell before the middle, basal vein a little before the 

 transverse. Male more slender, and much smaller; the last two ventral seg-
