21. Lopidea nigridea hirta, new subspecies 



Broader than nigridea, darker in color and more opaque 

 and hairy with the antennae thicker. Length 4 J/2 mm. 



Surface opaque, dull, clothed with short, stiff, black hairs and a few minute 

 white scale-like hairs intermixed ; costa quite distinctly arcuated ; sides of 

 pronotum moderately sinuated ; segment II of antennae about equal to basal 

 width of pronotum; base of vertex feebly impressed. Dextral male clasper 

 longer and slenderer than in nigridea, its apical margin minutely but quite 

 evenly crenulate, not at all produced and lacinate at its ventral angle. 



Color, dark brownish sanguineous, becoming clearer red on the pronotum 

 and costal margin of corium, the cuneus still lighter sanguineous; head 

 marked as in typical form but less distinctly; callosities black. 



Described from 29 examples representing both sexes, 

 taken by me on San Miguel Island, Santa Barbara Co., 

 Calif., May 20, 1919. The dark, opaque and hairy surface 

 will best distinguish this subspecies.

Type locality, San Miguel Island, Santa Barbara County,

Under the name nigridea Uhler, I have placed a species 

 commonly found on bushes in San Diego County and else- 

 where in California, during May and June, which agrees 

 exactly with Uhler's description except that segment II of 

 the antennae is as long as from the tip of scutellum to front 

 of eyes, thus assuming a clerical error in the original descrip- 

 tion. In this species the dextral male clasper is broad, con- 

 vex and strongly arched across the aperature of the genital 

 segment, with its apex obliquely produced in a long acute 

 spur which attains the dorsal line of the segment and is 

 minutely serrated exteriorly; interior to the base of this spur 

 is a shorter spine or tooth, sometimes minute. 



22. Ceratocapsus apicatus, new species 



Closely allied to fasciatus UhL, but with thicker antenna?, 

 a pale band across apex of corium as well as one at apex 

 of scutellum, a unicolorous membrane and darker legs. 

 Length A l / 2 to 5 mm. 



Male: Head slightly more porrect and vertex more convex than in fasci- 

 atus; antenna: stouter throughout; segment II as long as III and IV together. 

 Scutellum proportionately narrower than in fasciatus. Rostrum attaining 

 apex of intermediate coxae ; segment I attaining base of head. Apex of
