11. Neoborus illitus, new species 



Aspect of amoenus scutellaris but still darker; black, shaded 

 and varied with fulvous and brown. Length 5 y 2 mm. 



Head vertical, produced below the eye for a space equal to length of eye; 

 eyes unusually narrow, but little wider above; vertex with a large polished 

 paler spot either side; depressed base and a spot against either eye, punctate; 

 base strongly carinate; disk with faint arcs and a median sulcus; clypeus 

 smooth, polished, its base poorly distinguished; cheeks tumid; pronotum 

 broader anteriorly and more convex than in amccnus, shaped more as in 

 Lygus; coarsely punctate, polished; callosities oblong, highly polished, sides 

 carinate; scutellum with a few transverse dragged punctures; elytra closely 

 punctate; rostrum attaining base of intermediate coxae. Antennae rather short; 

 segment I a little shorter than distance between eyes; II slightly longer than 

 width of head including eyes; III and IV together two-thirds length of II; 

 IV two-fifths of III. Anterior angle of propleura below eye produced in a 

 narrow rounded lobe above base of anterior coxae. Sinistral clasper shaped

Described from two males and nine females taken on ash 

 trees at Fairfax, Marin Co., Calif., May 25, 1919. In form 

 of pronotum allied to Lygus but the genital and most other 

 characters indicate relationship with Neoborus. It shows 

 much variation in extent of pale colors.
