12. Phytocoris plenus, new species 



Very close to inops Uhl. ; differing in the absence of a pale 

 median annulus on second antennal segment, the more pro- 

 duced head and form of the male genitalia. Length 7 mm. 



Head prominent, nearly vertical ; viewed from the side extending below 

 the eye for a space equal to about three fourths the greatest length of the 

 eye; clypeus prominent, convex; gula oblique. In inops the head projects 

 hardly more than one half the greatest length of the eye, the clypeus is less 

 prorninent and the gula is but slightly oblique. Rostrum long, in the male 

 passing theapex of the fourth ventral segment, the basal segment broadly 

 linear, attaining the middle of the anterior coxae. Vertex viewed from 

 above flat, obviously wider than the eyes ; tumidly convex before ; in inops 

 not wider than the eyes and less convex before. Antennre about as in 

 inops, the first segment a little longer. Pronotal collum strongly differ- 

 entiated ; in inops but feebly so. Elytra with three polished areas, the basal 

 but poorly distinguished ; the apical conspicuous, resting on the base of the 

 cuneus. Hind femora long, almost attaining the apex of the membrane. 

 Apical margin of last ventral segment of male thickened, produced in a 

 subacute angle; sinistral notch right-angled, terminating above in a blunt, 

 blackish tooth which usually is somewhat longer than its width. In inops 

 this tooth is longer, terete and much more slender. Dextral notch nearly 

 as deep as the sinistral but more rounded at its fundus. In inops the ventral 

 apex of this segment is less acute with both notches more rounded, the 

 dextral shallower. 



Color cinereous mottled with fuscous as in inops but with the markings 

 more contrasted. Vertex distinctly striated anteriorly, its disk paler. Disk 

 of pronotum paler ; median line at base, sides and anterior angles infus- 

 cated; posterior submarg-inal line broken into dots, or nearly so. Antennae 

 fuscous, without pale annulations ; the basal segment dotted with pale ; the 

 extreme base of segments two and three white. Scutellum distinctly varied 

 with pale and fuscous, the anterior lobe fuscous with three pale marks, its 

 apex conspicuously pale. Elytra rather evenly mottled with the costa 

 dotted; corium with the three polished areas paler; cuneus pale within, 

 its outer and inner margins varied with fuscous. Membrane evenly 

 irrorate as in inops, its outer margin with two clear spots, the anterior at 

 apex of the cuneus ; nervures pale becoming fuscoiis at base. Legs irrorate 

 with fuscous; coxae and narrow base of femora white, the former bivittate 

 with fuscous ; tibiae fuscous irrorate with white and marked with four white 

 rings which are subequal to their interspaces, the basal on the hind pair 

 obscure ; tarsi fuscous with a pale annulus. Rostrum pale with its- apex 

 broadly fuscous. Sternum fuscous. Venter white, irrorate with fuscous, 

 with a narrow pale vitta and a few orange dots on either side, the genital 

 segments mostly fuscous. Behind each eye is a small tuberculate ivory 

 mark and behind that is a larger one on the incised line of the collum. 



Described from one male taken at Keen Camp in the San 

 Jacinto Mountains, June 8, 1917; one male taken on the hills 

 at Foster, San Diego County, April 11, 1914, and two males 

 taken at Lakeside, San Diego County, Calif., May 5, 1913. I 

 have seen no females I could certainly associate with these 

 males. 



This species is closely allied to hiops but it is well distin- 

 guished by the characters given above. In the allied fonns the
