15. Phytocoris geniculatus, new species 



Pale greenish, sprinkled and varied with whitish ; apex of 

 cuneus and the hind femora tinged with fulvous, the latter 

 armed at apex with two short black tubercules. Length 5 mm. 



Head moderately produced, nearly vertical before; vertex and clypeus 

 strongly convex leaving a deep suture between thenT, the vertex al>out one 

 half wider than an eye in male, nearly twice as wide in female ; frontal 

 stri?e conspicuous ; cheeks prominent but scarcely angled before. Rostrum 

 attaining third ventral segment ; its first segment reaching the base of the 

 head in male, a little longer in female. Antenn?e longer than the entire 

 body; first segment as long as head and pronotum together, linear, as thick 

 as two-thirds the superior vv^idth of an eye, sparsely clothed with fine pale 

 pubescence with a few longer stiff hairs intermixed ; second segment nearly 

 twice the length of first ; third three-fourths the length of second ; fourth 

 one half of third. Pronotum strongly narrowed before, its length one half 

 the basal width ; sides straight ; collum distinct ; callosities large, obscure. 

 Elytra somewhat polished all over, with two large areas more distinctly so. 

 Legs long, the hind femora surpassing the membrane and much flattened. 

 Apex of the male genital segment subacute ; the sinistral notch deep and 

 acutely angled, the margin rounded and unarmed above; sinistral hook 

 short, crescentic, blunt at apex, not nearly reaching to the apex of the 

 segment. 



Color pale greenish or yellowish, marbled with whitish, the two polished 

 areas of the elytra still whiter; apical half of cuneus and the hind femora 

 tinged with fulvous ; hind femora armed with a small deep-black tubercle 

 on either side at apex. Whole upper surface sparsely clothed with a 

 deciduous white pubescence with scattering longer fuscous hairs ; the ex- 

 treme tip of clavus with a minute tuft of black hairs, and in perfect ex- 

 amples there is another at the inner margin of the cuneus and probably a 

 third at its inner basal angle. Legs and antennae obscurely varied with 

 pale fulvous-brown and whitish ; the apex of the second and third antennal 

 segments often infuscated as is the apical half of the fourth. Beneath, 

 with coxse and base of feniora paler, the venter marbled more or less with 

 darker. Membrane white, more or less irrorate with minute brown points 

 and sometimes with a black point at the middle of the outer margin, the 

 nervures yellowish. 



Described from 32 examples, representing both sexes, taken 

 at Coachella and Palm Springs, Calif., May 14th to 19th, 1917. 

 At Coachella they were less mature and were found feeding on 

 a small-leaved Atriplex. This species may be distinguished by 

 its pale greenish white mottled aspect with a fulvous tinge to 

 the cuneus and hind femora and by the two black tubercles at 

 apex of these femora. 



Holotype (No. 402), male, and allotype (No. 403). female, 

 from Palm Springs, and paratypes in collection of the Calif- 

 ornia Academy of Sciences.
