 County (W. M. Giffard). ? July 28, Mt. Eddy (E. P. Van Duzee). 

 BRITISH COLUMBIA,— 2 July, 1914, Vancouver (R. H. Crystal). 



Deraeocoris incertus picipes new \ariety 



9. Length 5.5 mm., wklth 2.71 mm., larger than the typical incertus, ver- 

 tex more distinctly indented but otherwise does not appear to differ structurally ; 

 femora uniformly piceous, slightly pale only at the very apex ; hind tibiae 

 black, distinctly annulated with pale only on the apical half ; apical half of 

 hemelytra more broadly piceous than the typical form, cuneus black, pale on 

 basal half, frequently tinged with reddish. 



Holotypc: 9 July 26, Webber's Camp (alt. 7,800 ft.), Santa Cata- 

 lina Mts.. Arizona (H. H. Knight); Cornell University collection. 

 Paratypc: ? Aug. 4, Williams, Arizona ( H. H. Knight). 



Both specimens were beaten from white oak (Oncrcus sp.?) but 

 owing to the isolated specimens taken the occurrence on that tree may 

 have been merely accidental. This form may prove to be distinct from 

 i)iccrtits but in the absence of male specimens the identity can not be 

 established with certainty. 



Deraeocoris incertus carneolus new variety 



$. Length 4.7 mm., width 2.28 mm., nearly the size of the typical incertus. 

 marked similarly to picipes but all the black color replaced by reddish brown 

 and becoming piceous only in the darkest spots; vertex distinctly indented just 

 before the carina ; femora uniformly reddish brown, indistinctly pale at the 

 very apex ; hind tibiae reddish brown, a single pale annulation on the apical 

 half ; hemelytra, cuneus, and pronotum distinctly tinged with reddish, becoming 

 brownish in the darker parts. 



Holofxpe: ? August 2, liuachuca Mts., Arizona ( H. G. Barber) ; 

 author's collection. 



Deraeocoris rufusculus new species 



Closely related to incertus, smaller, darker colored, the cuneus red ; seg- 

 ment II of antennae beset at intervals with erect hairs which in length equal 

 the thickness of the segment ; the genital claspers indicate a close relationship 

 with incertus but certain differences are apparent (fig. 5). 



$ . Length 4.9 mm. Head : width 1 mm., vertex .29 mm., length .57 mm. ; 

 vertex not equal to the dorsal width of an eye, carina low but apparent, arcuated 

 cephalad, an oblique impression each side of vertex which unite on median line 

 at base of f rons ; collum broadly exposed, a groove separating it from the carina ; 

 color markings nearly identical with incertus. RostrMn^ length 1.98 mm., nearly 

 attaining posterior margins of hind coxae, piceous.
