*P. corticevivens Knight. 



Bull. Brook. Ent. Soc, xv, 63, pi. i, fig. 6, 1920. 



Male: Length 6.6 mm., width 2.3 mm. Very similar to fumatus, 

 differs in having the lower half of head black except for a small 

 spot at base of lora. Femora black, narrowly pale at base, with 

 a few small pale freckles near apices, the hind pair with a distinct 

 white oblique band just before apex which is broader and more 

 distinct on the anterior and ventral aspects. Genital claspers, 

 flagellum, and a tubercle above base of each clasper (fig. 149: 6), 

 distinctive of the species. 



Female: Very similar to the male but slightly more robust, 

 frequently lighter colored. 



Occurs on the bark of maple trees {Acer saccharum).

Male: Length 7 mm., width 2.3 mm. Head: Width 1.17 mm., 

 vertex .40 mm. ; vertex with large alutaceous spot each side of 

 median line, a pair of similar but smaller triangular spots at base 

 of f rons ; front obliquely striate each side of median line with five 

 blackish lines, transversely black between bases of antennae ; lower 

 half of face white, base of tylus, base of jugum, and spot on dorsal 

 margin at base of lorum, black, a somewhat interrupted reddish 

 band across middle of tylus. Rostrum, length 4.2 mm., attaining 

 base of genital segment, pale, brownish on apical segment. 



Antennae: Segment i, length 1.57mm., equal to the distance 

 between base of pronotum and a line drawn through eyes at a 

 point slightly before middle, blackish, dorsal aspect marked with 

 pale spots, the two largest spots on apical half ; ii, 3.1 mm., brown- 

 ish black, pale at base of dorsal aspect, a nearly obsolete yellowish 

 spot on middle as seen from dorsal aspect; iii, 1.79mm., blackish, 

 pale at base for space of .17 mm. ; iv, 1.3 mm., blackish. 



Pronotum : Embolar margins only very slightly arcuate ; fuscous 

 to blackish, a large translucent spot at apex of exocorium, 

 embolium irregularly translucent and darkened with fuscous ; 

 cuneus scarcely paler at base, a black tuft of hairs on inner margin 

 near base and a similar tuft at apex of endocorium; pubescence 

 blackish, intermixed with pale sericeous pubescence. Membrane 

 pale, thickly and rather uniformly conspurcate with fusco- 

 brownish ; veins dark, pale at apex of larger areole. 



Legs : Dark brownish black, coxae except spot near base, and 

 trochanters, pale ; femora irrorate with small pale spots, a slightly 

 larger pale spot on anterior aspect near apex but hardly suggestive 

 of a subapical band ; front and middle tibiae pale on middle and 

 with rather distinct pale band at middle of apical half ; tarsi 

 fuscous. 



Venter: Black, yellowish pubescent; genital segment and 

 claspers distinctive (fig. 149: 8).
