This particular variety and only this form was found associated 

 with and predaceous upon PJiyllapJiis fagi Linnaeus on the beech 

 (Fagus grand i flora), an aphid which rolls the leaves tmder tightly from 

 the margin. Specimens of castiis were taken at Batavia on apple trees 

 with the typical fasciolus, wdiich would indicate that both forms may 

 occur in the same situation. 



Deraeocoris grandis (Uhler) 



1887 Camptobrochis grandis Uhler, Ent. Amer. ii, p. 230. 



Length 6.4-7 mm. Distinguished by the long rostrum which reaches upon 

 the second segment of the venter; dorsum rather uniformly dark brown, median 

 line of pronotal disk rather broadly but only slightly paler than behind the 

 calli ; legs pale, apical half of hind femora and the basal half of tibiae biannu- 

 late with blackish. 



$. Length 6.4 mm. Head: width 1.03 mm., vertex .49 mm., length .67 

 mm., in profile more pointed, the base of tylus less prominent than in borealis, 

 otherwise very similar in structure ; yellowish brown, spot each side of vertex, 

 irregular spots each side of median line, two longitudinal lines and base and 

 apex of tylus, above and below base of antenna, bucculae and to some extent 

 on juga and lorae, dark brownish to black. Rostrum; length 2.97 mm., reach- 

 ing upon second segment of the venter, yellowish brown, darker at base and apex. 



Antennae: segment I, length .52 mm., yellowish, becoming darker each side 

 at base; II, 1.74 mm., yellowish, darkened on the apical one-third, scarcely 

 equaling the thickness of segment I, tapering on basal one-third to slender at 

 base, coarsely pubescent, a few exserted hairs nearly equal to twice the thick- 

 ness of the segment; III, .72 mm., infuscated, yellowish toward base; IV, .51 

 mm., infuscated, slightly paler at base; the last two segments slender, several 

 exserted hairs equal to twice the thickness of the segment.
