Vol. VIII] VAN DUZEE— NEW SPECIES HEMIPTERA 287 



16. Phytocoris censors, new species 



Closely allied to gcniciilatus ; differs principally in wanting 

 the fulvous color on the cuneus and femora and the black 

 tubercles on the apex of the hind femora and in having the 

 basal segment of the antennae distinctly white-pilose ; pale dull 

 greenish, evenly, finely marmorated with pale. Length 5 mm. 



In its structural characters this species is almost identical with genicu- 

 latus but there are certain differences. The first antennal segment is much 

 more thickly set with long stiflf white hairs ; the elytra do not show the con- 

 trasting polished areas which are quite evident in its ally and the tubercles 

 at the apex of the hind femora are concolorous or barely tipped with black, 

 the male genital characters seem scarcely to differ. 



Here the color is the same greenish white found in geniculafus but the 

 whole upper surface is quite uniformly marmorated with pale dull green. 

 The pale polished areas found in the allied form and the fulvous tint so 

 constant there are absent here. The antennas have the same mottled aspect 

 but none of the specimens before me show any trace of the fuscous apex 

 on the second and third segments found in the other form. The membrane 

 here is white with more or less of the fuscous dotting found in scniculatus 

 and the whole upper surface is dotted with soft white hairs as in that 

 species, but here I can detect in none of the specimens before me, all of 

 which seem to be perfect, the longer stiff brown hairs present in the allied 

 form. 



Described from two male and five female specimens taken at 

 Coachella and Palm Springs, Calif., May 14-21, 1917. Like 

 the preceding they were found on the whitish vegetation grow- 

 ing on the floor of the desert.

17. Phytocoris ventralis, new species 



Nearest gemculatiis ; small, short and broad with much the 

 aspect of a Psallus. White ; elytra sparsely sprinkled with black ; 

 broad apex of the second antennal segment, knees, and a vitta 

 on either side of the venter black. Length 4^/2 mm. 



Head vertical, produced below the eye for a distance nearly equal to the 

 length of the eye in the female, for about half this length in the male. 

 Rostrum long, reaching to middle of venter in the female and to the sixth 

 ventral segment in the male. Antennae as long as the entire body in the 

 male, a little shorter in the female ; first segment short, stout, as long as 

 the pronotum, clothed with soft white hairs which are nearly as long as 

 the thickness of the segment ; second segment as long as the corium ; third 

 two-thirds the length of second ; fourth about equal to first. Pronotum 

 short, rather steeply declinate ; hind edge slightly emarginate ; callosities 

 large, not conspicuous ; collum narrow, poorly distinguished. Elytra nearly 

 parallel, opaque white with a subhyaline, more polished area exteriorly at
