Henielytra: width 2.48 mm., embolar margin strongly arcuated; disk con- 

 vex, shining, finely pubescent, coarsely and rather irregularly black punctate; 

 ground color pale to testaceous, piceous surrounding each puncture and spread- 

 ing to connect in groups, tip of clavus, spot at base and larger one at middle 

 of corium, broadly across apices of corium and embolium, brownish black or 

 piceous. Cuneus pale, opaque, punctures chiefly concolorous, basal angle and 

 apical half brownish black. Membrane practically hyaline, the anal margin 

 and a small point at tip of smaller areole fuscous, brachium frequently infus- 

 cated. 



Legs: yellowish and darkened with reddish; femora strongly reddish on 

 apical half, an indistinct paler .band before apex, the extreme tips also 

 more yellowish ; tibiae biannulate on basal half with reddish, also a spot on 

 knee, broadly brownish at apices ; tarsi yellowish brown ; claws deeply cleft, 



arolia slender, bristle-like, erect, 

 nearly parallel but converging slight- 

 ly at apices. 



Venter: reddish, shining. pale 

 pubescent; genital claspers (fig. 39) 

 distinctive of the species.

slender than in the male, exserted 

 hairs and coloration not differing from male. 



Holotype: $ June 5, San Diego County, California (E. P. Van

Deraeocoris rufiventris new species 



Closely related to vanduceei but larger and differently colored ; dorsum 

 rufo-piceous, cuneus reddish on the basal half, legs arid ventral surface largely 

 reddish. 



S. Length 5.3 mm. Head: width 1.03 mm., vertex .51 mm., length .6 

 mm. ; structurally very similar to vanduzeei; yellowish to reddish, rather broadly 

 at apex and geminate mark on basal half of tylus, bucculae, and dorsal margin 

 of lorae, brownish to piceous. Rostrum, length 2.17 mm., attaining posterior 

 margins of middle coxae, yellowish to brown, piceous toward apex. 



Antennae: segment I, length .48 mm., f usco-brownish ; II, 1.51 mm., grad- 

 ually thickened from base toward apex, scarcely attaining the thickness of 

 segment I, dusky pubescent, length of longest exserted hairs equal to twice 

 greatest thickness of segment, yellowish, apical two-fifths black; III, .62 mm.,
