apex of cuneus than together wide ; hind femur six times longer than wide, 

 subparallel to beyond the middle, then a little narrowed to apex ; hind 

 tibiae with weak bristles not longer than thickness of the segment ; rostrum 

 attaining third ventral segment. Sinistral notch of genital segment shal- 

 low ; sinistral clasper linear, curved around the apex of the segment, at 

 base giving off an erect dorsal branch as long as the horizontal member 

 and rising to the dorsal line of the segment where it is bent abruptly- 

 backward, terminating in line with the apex of the genital segment; 

 dextral clasper small, distorted in the type, apparently triangular. 



Color yellowish testaceous, darker on head and pronotum; pronotum 

 with a fuscous basal vitta before the slender white hind edge, carrying 

 about six spots of tufted black hairs. From this dorsal vitta seven indis- 

 tinct longitudinal rays run to the anterior lobe, the lateral two the most 

 obvious. Scutellum with a pale median line more or less indicated and a 

 fuscous spot either side before apex. Corium with an indefinite fuscous 

 vitta following the claval suture and deflected along the apical margin 

 to apex of cuneus, this vitta marked with a few pale spots bearing clusters 

 of white hairs ; membrane pale, quite thickly irrorate with fuscous ; veins 

 yellowish. Hind femora more or less distinctly marbled with fuscous; 

 venter infuscated, the tip of the rostrum black. Apex of antennae infus- 

 cated, the base of III paler. Upper surface clothed with black hair in 

 fresh specimens. 



Described from one pair taken by me on Mt. Tamalpais, 

 Marin Co., Cal., June 23, 1918, and a female taken by Dr. 

 E. C. Van Dyke at same locality, September 19, 1909. This 

 is the most slender Phytocoris known to me and seems to 

 connect canescens with Hneatus and validus; the rayed prono- 

 tum and the fuscous vitta on the elytra will distinguish 

 females while the remarkable male genitalia will at once 

 locate that sex. 



Holotype, male (No. 690), allotype, female (No. 691), and 

 paratype in collection of California Academy of Sciences. 



13. Phytocoris sonorensis, new species 



Aspect of canescens but larger and broader, the elytra and 

 antennse more varied ; sexes similar. Length 7 mm. 



Male: Head vertical, produced below the eye for a space greater than 

 the length of the eye; eyes small, but moderately produced inferiorly; 

 front a little convex between the antennae. Antennae long; segment I a 

 fourth longer than pronotum; a little thicker near the base; H twice as 

 long as I; HI a third shorter than H; IV one fourth shorter than I. 

 Elytra together nearly as wide as their length to tip of clavus. Rostrum 

 passing hind coxae. Hind femora nearly equal to length of elytra to tip of 

 cimeus, slender, nine times longer than wide, widest near base then 

 gradually a little narrowed to apex. Sinistral notch of genital segment 

 rather small, right-angled, margin oblique dorsally and there carrying a 

 large curved, suberect lenticular tooth arising from the produced angle 

 of the apical tergite ; sinistral clasper large and broad, its dorsal angle 

 forming a blunt tooth, the apical portion abruptly slender and incurved; 

 dextral clasper small, Ijang along the ventral wall of the notch.
