paler. Elytra dusky on the disk, becoming rufous at tip of corium and 

 anterior to the white angular spot at apex ; cuneus rufous ; membrane 

 white, irrorate with fuscous, leaving two white marginal spots. Below 

 rufous, the pleural pieces piceous ; coxae white ; legs white, the femora 

 marked with fuscous apically, the posterior more broadly so, with two 

 white annuli ; tibiae faintly triannulate with fuscous. Antennae pale brown; 

 segment I white marked with rufous; II with base and a broad annulus 

 beyond the middle white; III white at base. 



Described from one male taken by Mr. Fordyce Grinnell on 

 Mt. Wilson, Los Angeles Co., Cal., August 10, 1909. The 

 uniform rufous color, pale head and coxae, flattened black 

 hairs above, and the cluster of white bristles on first antennal 

 segment with the genital characters will sufficiently distinguish 

 this species. 



Holotype, male, in collection of the author. 



15. Phytocoris onustus, new species 



Allied to eximiiis Reut., a little larger and darker with 

 darker antennae and, like that species, belonging to the group 

 with marmorate membrane ; differing widely in male genitalia. 

 Length 7 mm. 



Male : Head a little longer and more oblique than in eximius, exceeding 

 the eye for a space equal to the greatest width of the eye ; vertex more 

 flattened. Antennae slender; segment I a little thickened basally, as 

 long as from their insertion to the base of the pronotum ; II thinner, 

 more than twice the length of I and about equal to the costal margin of 

 the corium ; III and IV together equal to II ; III longer than I, IV shorter. 

 Pronotum as in eximius, its length three fifths its basal width, sides 

 straight, humeri prominent. Scutellum equal to pronotum in length ; ros- 

 trum passing hind coxae ; legs as in eximius. Male genital segment large, 

 convex ; sinistral notch right-angled, the dorsal angle obtuse, unarmed ; 

 sinistral clasper large, sickle-shaped, with a prominent dorsal tooth near 

 its base ; black with luteus apex ; dextral clasper long as the sinistral, 

 bent near the base and armed there with a dorsal tooth equal to its own 

 width, at apex paler and curved inward and upward, subacute. 



Color yellowish cinereous, much invaded with fuscous ; head pale, the 

 disk of the cheeks, apex of clypeus and about six arcs on the front 

 fuscous ; disk of pronotum pale, sides and base broadly blackish, the latter 

 area broken at the middle ; hind edge white ; callosities marked with a 

 double pale arc ; scutellum pale with a blackish vitta either side the pale 

 median line, these diverging posteriorly, basal angles with a fuscous 

 spot. Elytra fuscous, obscurely irrorate with pale and each marked with 

 three polished areas, one subbasal, one median and one apical invading 

 the base of the fuscous cuneus. Membrane pale fuscous marmorate with 

 whitish forming a pale spot at apex of cuneus and two obscure discal areas ; 

 nervures fuscous, the cubital thick and black. Antennae fuscous ; seg- 

 ment I irrorate with pale with a few black bristles near base ; II with base 

 narrowly pale ; III with base and extreme tip pale. Legs irrorate with 

 fuscous at apex, the hind femora becoming fuscous at apex with paler
