 basal angles, median line and apex, pale. Sternum and pleura brownish to 

 piceous ; ostiolar peritreme white. 



Hemelytra : width 2.65 mm. ; testaceous to brownish, somewhat translucid ; 

 corium with whitish spot near base, a larger similar spot on the apical half 

 but more or less divided by fusco-piceous ; narrowly at base, between pale 

 spots and more broadly at apex of corium, fusco-piceous. Cimeus testaceous, 

 translucid, apex dark brownish to piceous, inner margin next to base of smaller 

 areole pale. Membrane clear, fumate cloud on apical half, veins and slightly 

 invading the membrane, dark brownish.

 reddish brown annulations ; tibiae triannulate with pale and with fusco-brown- 

 ish; tarsi brownish to piceous. 



Venter: brownish to piceous, shining; genital claspers are not appreciably

Deraeocoris appalachianus new species 



Closely related to barberi, general aspect more suggestive of a pale nigritulus 

 but differs in the glabrous dorsum and short hairs on tibiae; scutellum uni- 

 formly brownish, less convex than in barberi; tibiae reddish brown, broadly 

 pale on the apical half. 



9. Length 6.2 mm. Head: width 1.17 mm., vertex .57 mm., length .58 

 mm.; facial angle a right angle, outline of tylus more rounded and the head 

 less pointed than in barberi; marked similarly to barberi but the black color 

 replaced with brownish black. Rostrum, length 2.48 mm., attaining middle of 

 the hind coxae, dark brownish, basal segment piceous. 



Antennae: segment I, length .51 mm., fusco-brownish; II, 1.57 mm., slender, 

 thickened on the apical one-fourth but not attaining the thickness of segment I. 

 length of exserted hairs equal to twice thickness of segment at middle, fusco- 

 brownish, darker at apex ; HI, .68 mm. ; IV, .54 mm. ; last two segments brown- 

 ish to black. 



Pronotum: length 1.34 mm., width at base 2.34 mm., anterior angles 1.14 

 mm., collar .83 mm.; disk more closely and uniformly punctured than in barberi, 

 rather uniformly dark fusco-brownish, calli and anterior margin of disk brown- 

 ish black; propleura dark brownish, paler at lower margins; xyphus nearly 

 flat, testaceous, pale pubescent. Scutellum more flattened than in barberi, smooth 

 and shining, minutely rugulose across the middle, uniformly dark brownish. 

 Sternum and pleura dark brownish ; ostiolar peritreme darkened with brownish. 



Hemelytra : width 2.88 mm., embolar margin slightly more arcuate than in 

 barberi; fusco-brownish, clavus and base of corium more yellowish and semi-
