\'0L. VIII] VAN DU ZEE— NEW SPECIES HEMIPTERA 297 



the apex of the sinistral clasper; this sinistral clasper convex, ligulate, 

 rounded at tip and incurved against the apex of the genital segment ; both 

 claspers virith a few long stiff hairs ventrally. 



Color black, more or less covered with a white bloom, especially on the 

 head and pronotum ; head obscurely marked with pale next the eyes and on 

 the cheeks. Posterior lobe of pronotum and elytra obscure sanguineous, 

 paler on the humeri and base of the corium ; the clavus and inner field of 

 the corium obscured or blackish. Scutellum blackish; membrane black; 

 sides of venter more or less tinged with reddish. Upper surface sparsely 

 clothed with very short appressed pale hairs. 



Described from 69 examples taken at Palm Springs, Calif., 

 May 22, 1917, on Dalca ernoryi found growing on the floor of 

 the desert a mile or two east of town. This species is nearest 

 picta in size and genital characters but is very distinct from 

 any previously described species. 



Holotype (No. 417), male, allotype (No. 418), female, and 

 paratypes in collection of California Academy of Sciences. 



27. Hadronema albescens, new species 



Allied to decorata Uhl. ; white or almost lead-color ; head, 

 base of antennae, scutellum and femora fulvous ; inner angle of 

 corium with a blackish spot ; length 4 mm. 



Head about as in miUtaris, the vertex flatter than in robusfa. Rostrum 

 attaining the middle of intermediate coxae, its first segment scarcely sur- 

 passing the base of the head. Antennae about as in robusfa; second and 

 third segments equal in length ; first and fourth subequal, the first thickened 

 and fusiform. Pronotum rather less roughened than in the allied species, 

 the callosities large but not prominent ; anterior margin showing a flat 

 membranous expansion covering the base of the head but this cannot 

 properly be designated as a collum and becomes a mere margin in the 

 allied forms ; carinate lateral margins obtuse ; humeral angles rather prom- 

 inent. Scutellum flattened. Elytra parallel ; costal margin sharply distin- 

 guished and narrowly foliaceous ; cuneus unusually long and narrow. 

 Upper surface of the pronotum, scutellum, clavus, and disk of the corium 

 clothed with scattering stiff fuscous hairs springing from fuscous dots ; 

 sides of corium and cuneus with a softer white pubescence. Legs long, 

 the tibiae armed with long stiff black bristles, much longer than the thick- 

 ness of the member. Male genital characters obscure. Dextral clasper 

 broad, flat, bent in its own plane at about the middle and truncate at apex ; 

 sinistral clasper produced in a long acute black spine. 



Color white or somewhat lead-color ; head, scutellum and coxae of a pale 

 dull fulvous, the borders of the eyes, cheeks, lorae and bucculae white ; basal 

 segment of the antennae and femora of a deeper fulvous. Antennre, except 

 basal segment, rostrum, tibiae and tarsi black; the base of the second anten- 

 nal segment, of the rostrum and of the tibiae paler or fulvous ; pronotum, 

 venter, clavus and disk of the corium more or less darkened or lead-color 

 and punctured with fuscous at base of the black hairs. Inner angle of 

 corium with a transverse blackish spot not passing ithe radial vein. Mem- 

 brane white, somewhat infuscated in the areoles, the veins blackish. Hind 

 femora and pygofer of the female blackish at base.
