Deraeocoris (Heteroptera, ^Iiridae) 111 



Hciiiclyfra: width 2.28 mm.: structurally very similar to z'alidiis; yellowish 

 translucent, punctures black ; bordering the commissure, a broad elongate spot 

 occupying the apical half of corium, embolium toward the apex and slenderly 

 along the outer edge, blackish. Cuncus testaceous, slightly translucent, punc- 

 tures and the apical half black. Membrane distinctly fuscous on the apical half 

 and projecting basally somewhat between the areoles, veins brownish black at 

 apices of areoles, in darkest specimens somewhat invading the meinbrane ; are- 

 oles within, bordering the veins without and at tip of cuneus. pale. 



Legs : lurid to translucent brownish, anterior faces of femora with a linear 

 series of fuscous points, the apices narrowh- pale; tibiae indistinctly triannulate 

 with paler ; tarsi piceous, slightly brownish at base. 



I'eiiter: piceous black, shining; genital claspers (PI. X) distinctive of the 

 species. 



$. Length 4.8 mm. : very similar to the male, head more broadly pale and 

 the corium with very little blackish. 



Holotype: $ June 21, 1914, San Diego Co.. Calif. (E. P. \'an 

 Duzee) ; collection of E. P. A'an Duzee. 



Allotype : same data as the type. Paraiypc : ?, taken with the 

 types. ]\Ir. \'an Duzee took the specimens on an "elderherry tree." 



KEY TO THE SPECIES OF GROUP II 



In this group the body form, genital claspers, and punctate scu- 

 tellum all point to a close relationship with group I, while the non-cleft 

 claws exhibit an affinity with the species of group V. D. diveni is 

 very distinct and would merit the separation into a new group were 

 other species discovered having similar characteristics. 



1. Dorsum heavily pubescent or hairy ....-••" 

 Dorsum glabrous or practically so . . • • ■ . . - 



2. Femora deep black, apices distinctly pale, tibiae biannulate with pale; 



pronotal disk of female largely pale, the calli and basal angles black; 

 disk of male largely black, narrow median line and a stripe behind 

 lateral angles of calli pale to brownish, black color on frons never 

 forming transverse bars ; dorsal width of an eye in the male not equal 



to width of vertex atrkriitiis n. sp.^ p. 112 



Femora not as the above, more or less brownish black or reddish, fre- 

 quently biannulate with paler on the apical half; tibiae variously 

 banded; dorsal width of an eye in male equal to width of vertex . 3 



3. Femora narrowly pale at apex and a second band just before; hind 



tibiae distinctly biannulate. a third pale indication just below the knee; 

 hemelytra more or less pale. apex, middle, and narrow base of corumi 

 blackish; cuneus black, pale on the basal half . iiiccrtus n. sp. p. 114 

 Femora pale only at the very apex, or if a second annulation is indi- 

 cated, then the cuneus reddish ; hind tibiae biannulate or banded with 

 pale only on the apical half; cuneus usually reddish, corium some- 

 times like the above
