Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 271 



Described from two males and four females taken by Mr. 

 Giffard near Cloverdale in Sonoma Co., August 3, 1916; one 

 male and three females taken at Los Altos, July 26, 1916, and 

 two females taken in Placer Co., August 19, 1916, and one 

 male and two females taken by me at Colorado Springs, 

 Colo., July 8, 1902. In the characters of the head and an- 

 tennae this species is close to genus Pamillia but the form of 

 the pronotum and elytra are those of Ceratocapsus where 

 the species should probably be placed. On Mt. Diablo Mr. 

 Gififard took seven females that seem to differ in no respect 

 except color. These are pale castaneous with the elytra, at 

 least at base, more yellowish, the cuneus almost sanguinous 

 and the base of the membrane pale.

136. Lopidea aculeata, new species 



Very similar to robinice Uhl. with a shorter pronotum, a black lower 

 surface and dififerent male genitalia. Length to tip of membrane 6^ to 

 7 mm. 



Vertex with a linear depression before the slender basal carina, before 

 swollen about as in robinics. Antennae a little shorter than in the allied 

 species ; second segment nearly as long as the head, pronotum and scu- 

 tellum together, considerably longer than the basal width of the prono- 

 tum; third one-half the length of the second. Pronotum one-half as long 

 as its basal width, in robinice two-thirds as long, angulate transverse de- 

 pression before the callosities, reaching almost to the inner angle of the 

 eyes, in robinice much shorter, with the callosities prominent and rounded 

 within, while in aculeata they are more elongated, oblique and less convex 

 toward the median line than in robinice; surface posteriorly a little more 

 convex than in the allied species ; sides slightly concave with the carinate 

 edge more obtuse. Elytra narrow, the costa but very feebly arcuated ; sur- 

 face almost smooth, obscurely wrinkled on the clavus, clotlied as is the 

 pronotum, with scattering short black hairs, which want the black dots 

 at their base. 



Dextral hook of the male genitalia broad, ligulate, incurved, pale, 

 broadly rounded or almost truncate at apex; produced just before its 

 dorsal apical angle in a long acute, curved process which is serrated be-
