Vol. VIII] VAN DUZEE—SEW SPECIES HEMIPTERA 283 



female has the vertex broader and the rostrum shorter than 

 their males and the same may be true in this species. For ready- 

 recognition the banding- of the tibiae will be found a convenient 

 character: In plemis the anterior tibiae are narrowly black at 

 either end with three dark rings between; in inops and related 

 forms the apical ring is broad and there are but two between 

 that and the narrow basal one. In inops the second antennal 

 segment is fuscous with a pale median annulus. In the San 

 Diego County males of pleints the basal half of the second an- 

 tennal segment is paler. 



Holotype (No. 398), male, from Keen Camp, in collection 

 of the California Academy of Sciences.

13. Phytocoris fraterculus, new species 



Allied to inops, averaging larger and darker with a longer 

 head and wanting the median pale annulus on second antennal 

 segment. Differs from plcnus in the shorter pronotum and by 

 the presence of a distinct pale annulus near the apex of the hind 

 femora, and from both species by the characters of the male 

 genitalia. Length 7 to 7>4 mm. 



Head produced below the eye for a space nearly equal to the length of 

 the eye ; clypeus prominent ; gula oblique ; cheeks prominent, rounded, not 

 angularly produced as in inops. Vertex flattened, scarcely advanced to the 

 line of the clypeus, not projecting before it as in inops. Rostrum attaining 

 apex of second ventral segment; its first segment reaching to middle of 

 anterior coxse. Antennae slender; first segment linear, hardly longer than 

 the pronotum; second equal to the costal margin of corium ; third about 

 equal to first ; fourth tvi^o-thirds the third ; first armed with stiff hairs which 

 are a little longer than the thickness of the segment. Pronotum short, its 

 length one half its basal width ; sides rectilinear ; base slightly emarginate ; 

 collum distinct as in plcnus. Elytra with three polished areas as in plenus. 

 Legs long, about as in plenus; the hind femora reaching nearly or quite to 

 apex of membrane, distinctly shorter than in inops. Sinistral margin of 

 the genital segment with its superior angle unarmed, rounded ; the sinistral 

 hook long and curved as in inops, with a rounded notch at base; ventral 

 aspect of the genital segment rounded or subacute at apex about as in 

 inops. Surface clothed with close black pubescence and softer white de- 

 ciduous hairs. 



Color cinereous mottled with fuscous as in the related species, sometimes 

 pale brownish and fuscous. Vertex distinctly striate; clypeus, lorse and 

 cheeks brown, bordered with pale ; hind margin of the eye and usually a 

 median spot on base of vertex whitish. Pronotum brown or fuscous becom- 

 ing pale about the callosities and blacker toward the margins ; the hind edge 

 narrowly white behind a blackish vitta which may become broken into six 

 lobes or spots. Scutellum brown with basal angles and a geminate median
