9 Moderate size; deep tlack. Clypeus plainly emarginate in 

 middle, clypeus, face, vertex, basal joint of antennae, prothorax, 

 coxae I, and metanotum with long black hair, fewer and shorter hairs 

 elsewhere, but tip of abdomen bristly, and scattered, long hairs on 

 venter. Antennae slender, third joint much longer than first; fourth 

 shorter, but longer than first; a deeply impressed line from antennae 

 to ocelli; hind ocelli about as close to eyes as to each other; vertex 

 straight across, face barely narrower at upper than at lower end of 

 eyes. Pronotum broadly arcuate behind. Metanotum with a median 

 groove. Abdomen of moderate length, slightly depressed on basal 

 segments. Legs slender, a few short hairs on femora of front and mid 

 legs; tarsus of front legs with a comb of long curved spines, four on 

 outer side of basal joint. Spur on hind tibia little more than one 

 half as long as basitarsus, spines on hind tibia not as long as width of 

 the joint. Wings deep black; second submarginal cell about one 

 fourth longer than broad, third shorter, subtriangular, less than one 

 half as long above as below, receiving second recurrent vein at middle, 

 this recurrent arising much beyond the middle of apical cell; basal 

 veins interstitial. Length, 12 mm.

9 Deep blue; the wings blue-black, beautifully iridescent; structure 

 similar to P. phUadelphicus. The clypeal margin perhaps not quite as 

 deeply emarginate as in the typical form, and the vertex between the 

 eyes a little broader, and the third antenna! joint rather longer; the 

 ventral segments less hairy, and the minute spines on the upper surface 

 of the femora are more numerous, especially on the front femora. 



More distinct from the type than the variety /■'. p. sericaixis, and 

 possibly a distinct species.

I prefer, for the present, to keep this genus in its broad sense and 

 make the following subdivisions of it which may be considered as of 

 subgeneric value. This arrangement is based on the female, but in 

 .some cases males can also be placed in it.
