base; iii, .98mm., black; iv, 84mm., black. Genital claspers 

 (fig. 149: 22) distinctive of the species.

 P. fulvus Knight.

Male: Length 6mm., width 2mm. Head: Width 1.08 mm., 

 vertex .34 mm. Antennae : segment i, length .88 mm., yellow but 

 with paler spots apparent, dusky pubescent, setae yellowish to 

 dusky; ii, 2.5mm., yellowish, infuscated apically; iii, 1.25mm., 

 black, yellowish at base ; iv, .93 mm., black. 



Suggestive of mundus but larger, more elongate and paler in 

 color; pale yellowish, darkened with fulvous on outer half of 

 clavus and inner half of corium ; apical half of femora perceptibly 

 darkened but small pale irrorations are visible; membrane pale, 

 uniformly tinged with fumate, the veins fulvous ; genital claspers 

 and flagellum (fig. 149: 23) distinctive of the species.

P. pinicola Knight. 



Bull. Brook. Ent. Soc, xv, 59, 1920. 



Male: Length 5.2 mm., width 1.8 mm. Head: Width .96mm., 

 vertex .36mm. Antennae: Segment i, length .54mm., pale 

 yellowish to dusky, dorsal surface with pale glabrous spots, two 

 brownish black setae set on margin of each glabrous spot; ii, 

 1.97mm., blackish, paler beneath; iii, .92mm., blackish, narrowly 

 pale at base ; iv, .50 mm., blackish. 



In coloration most suggestive of conspersipes but the genital 

 structures show it to be more closely related to mundus; more 

 slender than conspersipes, spots on femora and tibiae less distinct, 

 usually orange-yellow; genital claspers and flagellum distinctive 

 of the species (fig. 149: 17). 



Female: Similar to the male in coloration, but shorter and more 

 robust in form.
