Deraeocoris pinicola new species 



Closely related to barberi but differs in the antennae and genital claspers 

 and usually is smaller in size; median line of front and just before the calli, 

 pale to ivory-white, antero-lateral angles of calli invaded with pale; general 

 coloration pale to grayish and darkened with blackish, not at all tinged with 

 brownish. 



$. Length 5.7 mm. Head: width 1.08 mm., vertex .53 mm., length .57 

 mm. ; carina obsolete, collum broadly exposed, black and shining, separated 

 from the vertex by a groove ; pale to ivory-white, front with a black arc each 

 side of median line, broken into transverse bars in pale specimens ; bordering 

 front margin of eyes and terminating in a projection on vertex, base and apex 

 of tylus with two connecting longitudinal lines, stripe from lower margin of 

 eye across gena and upon the buccula, apically on lorae, and frequently 

 a spot on juga, black, eyes dark brown. Rostntiii, length 2.34 mm., reaching to 

 near apices of hind coxae, piceous, paler at the joints. 



Antennae: segment I, length .42 mm.; II, 1.51 mm., slender on basal one- 

 fourth, practically cylindrical on the apical half and equal to segment I in 

 thickness, dusky pubescent, length of exserted hairs about equaling thickness of 

 segment; III, .6 mm.; IV, .5 mm.; all the segments black, shining. 



Pronotum: length 1.34 mm., width at base 2.19 mm., anterior angles 1 mm.; 

 collar .74 mm., f usco-grayish, opaque ; disk moderately convex, coarsely black 

 punctate but more closely and less deeply on the posterior half, lateral margins 

 slenderly carinate, nearly straight, anterior angles rounded but distinct ; calli 

 convex, partially separated by a pair of punctures, black and shining but in- 

 variably invaded by pale at the latero-anterior angles where a black arc extends 

 to front margin of disk, pale to ivory-white just before; posterior lobes of disk 

 becoming darkened with piceous and black, slender basal margin pale ; pro- 

 ])leura black punctate, black and opaque surrounding the dorsal half of coxal 

 cleft, margins more or less pale; xyphus nearly flat, infuscated on disk, an- 

 teriorly and the carinate lateral margins pale. Seulelliiin moderately convex, 

 smooth and shining, black, basal angles, apex and median line more or less,
