25. Lopidea occidentalis, new species 



Closely allied to media Say and apparently the western rep- 

 resentative of that species ; above sanguineous, scutellum, cal- 

 losities, antennpe and markings on the head black ; right clasper 

 of male without subapical tooth. Length 5>^ mm. 



Structural characters very near to those of media. Vertex a little fuller 

 and more convex. Antennae shorter, as long as from apex of head to base 

 of cuneus. Dextral clasper of male broad, strap-shaped as in media but 

 without ithe subapical tooth, the basal tooth shorter, more slender and in- 

 curved from near its base, just attaining the base of the dorsal tooth of 

 the pygofer; this median dorsal tooth on the pygofer is much larger in 

 the present species, surpassing the anal tube, slender and hooked at apex. 

 Sinistral clasper elongate-triangular, acute at superior apical angle ; fringed 

 ventrally with long pale hairs. In media the dextral clasper is armed with 

 a produced tooth before its apex dorsally; the basal tooth is very long, 

 curved, and fully equals the dorsal tooth of the pygofer; this dorsal tooth 

 mudh shorter and armed with an apical hook ; the sinistral clasper, also, is 

 bilobed, both lobes being broadly rounded at apex. 



'Color sanguineous as in media; clypeus, two longitudinal areas on the 

 vertex and its base black, these markings sometimes extended so as to cover 

 most of the surface. Callosities black, contiguous. Scutellum black tinged 

 with red at apex. Clavus and inner field of corium more or less infuscated, 

 darker in the male. Membrane blackish, iridescent, the nervures black. 

 Antennae and legs black or nearly so, the femora invaded with pale at apex. 

 Sternum and middle of venter more or less clouded with black, the male 

 genitalia red. Rostrum piceous, reaching the hind coxse. 



Described from 39 specimens, representing both sexes, taken 

 at Palm Springs, Calif., May 19, 1917, on Croton califomicus, 

 found growing near the mouth of Andreas' Canyon. The 

 male genital characters and shorter antenn?e will distinguish 

 this species from its eastern ally. The general color, also, is 

 deeper, more as in r enter i and ccBsar.

26. Hadronema infans, new species 



Small, black; posterior lobe of pronotum and elytra dull 

 sang-uineous ; inner field of corium obscured, the membrane 

 black; length 3>4-4 mm. 



Head as in picta, the basal impression of the vertex deep; antennae short, 

 as long as from apex of head to base of cuneus. Basal lobe of scutellum 

 covered by the pronotum, the apical lobe convex, without a basal depres- 

 sion. Rostrum attaining the apex of hind coxae; tip of venter reaching 

 to apex of the cuneus. Male genital characters distinctive. Dextral clasper 

 elongate-conical, curved and almost hooked at apex which passes just above
