becoming suffused with piceous, the median line more pale; propleura pale 

 brownish, opaque, p^ler at margins, more finely punctate than disk ; xyphus 

 nearly flat, yellowish to brownish. Sciitellum convex, smooth, dark reddish to 

 brownish, median line paler, becoming blackis'h each side at base ; mesoscutum 

 scarcely exposed, reddish brown. Sternum and pleura brown, opaque ; ostiolar 

 peritreme pale, becoming brownish above. 



Hemelytra: width 2.51 mm., convex, embolar margin arcuate; black punc- 

 tate but more finely than on pronotal disk, pale, becoming stained with brownish 

 and fuscous ; slender edge of embolium but broadly at apex, apex of corium 

 and spot at middle, piceous. Cuneus pale but not translucent, punctures, apical 

 one-third, and narrowly at base, black. Membrane transversely pale across 

 middle, brownish to fuscous on apical one-third, brachium and narrowly each 

 side dark fuscous. 



Legs: coxae pale, becoming reddish brown on anterior face; femora red- 

 dish brown, more translucent basally ; tibiae fusco-brownish to blackish, biannu- 

 late with pale, frequently a third pale indication at knee ; tarsi brownish to 

 blackish, claws brown, distinctly cleft ; arolia erect, bristle-like, parallel or 

 slightly divergent apically. 



Venter: pale to reddish or reddish 

 brown, becoming piceous on base of 

 genital segment, pale pubescent ; gen- 

 ital claspers (fig. 20) distinctive of 

 the species. 



9. Length 4.5 mm., width 2.65 

 mm., slightly more robust but very 

 similar in color to the male ; seg- 

 ment II, length 1.22 mm., slender, 

 slightly enlarged on the apical one- 

 fourth, pale pubescent, exserted hairs 

 equaling greatest thickness of seg- 

 ment, piceous, a dark brownish band just beyond middle.

Holotypc: S August 3, Grand View, Grand Canyon, Arizona 

 (H. H. Knight) ; Cornell University collection. Allotype: taken with 

 the type. Paratypcs: S 45 taken with the types on the cliff rose. 

 Cozvania mcxicana, while the shrub was in flower. $ 29 June 18, 

 Ashfork, Arizona (Barber & Schwarz). 



This species doubtless breeds on the cliff rose and was not merely 

 attracted by the flowers as may be the case with some insects. D. man- 

 it ou intermedins bears a close resemblance to bullatus but the color of 

 the legs as well as the structure of the claws makes their separation 

 simple. 



Deraeocoris convexulus new species 



Very similar to bullatus, paler above and without red on scutellum and 

 venter, hind femora twice banded on the apical half with reddish brown ; left
