626 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



*P. conspurcatus Knight. 



Bull. Brook. Ent. Soc, xv, 61, 1920. 



Male: Length 5.9 mm., width 2.1mm. Distinguished by the 

 dark conspurcate membrane and by the pale band at middle of 

 antennal segments ii and iii ; dorsum thickly clothed with black 

 deciduous scale-like hairs and intermixed with small patches of 

 white tomentum. 



Head: Width 1.06 mm., vertex .34 mm., infuscated similarly to 

 eximius. Rostrum, length 2.6 mm., attaining base of genital seg- 

 ment. Antennae: Segment i, length 1.2mm., black, irregularly 

 irrorate with white, beset with from fourteen to sixteen pale setae ; 

 ii, 2.5 mm., black, annulated at base with pale, a second pale band 

 beginning at middle and covering a space of .3 mm. on base of 

 apical half; iii, 1.48mm., pale at base and again at middle; iv, 

 1.1 1 mm., black. 



Pronotum : Length 1.54 mm., width at base 1.7 mm. ; form and 

 coloration very similar to eximius, but differs by the presence of 

 black scale-like hairs ; scutellum thickly covered with white 

 tomentum. 



Hemelytra: Rather uniformly darkened, a pale triangular spot 

 at tip of corium bordering the cuneus ; thickly clothed with black 

 scale-like hairs and intermixed with small patches of white tomen- 

 tum. Membrane thickly conspurcate with dark fuscous, cubitus 

 pale at apex of larger areole, conspurcate spots more sparsely 

 placed near apex of cells. 



Legs : Marked very similarly to those of eximius, the pale band 

 near apex of hind femora more or less interrupted on under side. 

 Venter : Dark fuscous to blackish, more or less pale on under side 

 at base ; genital claspers and the long tubercle above base of left 

 clasper (fig. 149: 16), distinctive of the species. 



Female: Very similar to the male in size and coloration. 



This is a predaceous, bark-inhabiting species which the writer 

 has taken on the boles of Linden (Tilia), Pear (Pyrus), and Maple 

 (Acer) ; frequently attracted to lights.

 *P. sulcatus Knight. 



Bull. Brook. Ent. Soc, xv, 64, 1920. 



Male: Length 6 mm., width 1.8 mm. In form very similar to 

 fumatus but smaller ; pronotum more distinctly sulcate at sides 

 and immediately behind the calli ; pale annulations more distinct 

 at base and middle of segment ii; dorsum distinctly paler, outer 

 half of clavus and inner apical angles of corium blackish; femora 

 broadly pale at base, irrorate with large pale spots on apical half. 

 Genital claspers, flagellum, and the large thick tubercle above base 

 of left clasper (fig. 149: 15), distinctive of the species. 



Female: Very similar to the male in coloration, but in form more 

 robust and the embolar margins more distinctly arcuated.
