Vol. IX] VAN DUZEE— NEW HEMIPTEROUS INSECTS 341 



Antennae slender ; segment I as long as head and pronotum together, 

 linear with a few long weak bristles ; II more than twice the length of I ; 

 III one fourth longer than I, IV as much shorter. Pronotum twice wider 

 than long; scutellum unusually convex, longer than wide at base. Elytra 

 nearly parallel ; hind femora seven times as long as wide ; a little narrowed 

 on basal and apical one fourth ; hind tibiae very long, almost equal to 

 elytra including the membrane ; rostrum reaching third ventral segment. 

 Sinistral notch of genital segment shallow, its dorsal angle produced in a 

 short upright tooth ; sinistral clasper, large, convex, in form of a broad 

 triangle with its apical margin a little concave ; lower angle curved and 

 hidden beneath the apex of the segment, dorsal angle acute and incurved, 

 attaining the dorsal angle of the segment. 



Color whitish testaceous, tinged with yellow on head and pronotum ; 

 a cloud on the vertex, about seven arcs on the front and a transverse vitta 

 across cheeks and clypeus ferruginous ; sides of pronotum broadly, the 

 narrow base and median line, deep black, leaving a squarish discal spot 

 which includes a few ferruginous marks about the callosities and on the 

 collum; hind edge slenderly white. Scutellum' fuscous with the median 

 line and sides marked with whitish. Elytra dusky testaceous, a little more 

 clouded along the apical margin, the veins and costa with inconspicuous 

 brown and white marks ; membrane fuscous obscurely irrorate with pale ; 

 a spot at apex of cuneus and a discal arc whitish. Beneath mostly blackish 

 fuscous with the coxae white. Legs whitish, the femora rufous-brown 

 irrorate with whitish ; tibiae varied with brown, the anterior triannulate. 

 Basal segment of antennae rufous-brown, dotted with white, two of the 

 spots larger ; II pale brown with a white basal annulus twice longer than 

 the thickness of the segment, followed by a fuscous cloud; III and IV 

 infuscated, the former white at base as in II. Surface clothed with 

 black hairs and white tomentum. 



Described from one male taken by me at Cayton, Shasta 

 Co., Cal., July 19, 1918. The male genital clasper is so dis- 

 tinctive the species cannot be colnfounded with any other 

 known species; the markings of the head and pronotum are 

 about those found in palmeri. 



Holotype, male (No. 689) in collection of the California 

 Academy of Sciences. 



12. Phytocoris tenuis, new species 



Aspect somewhat of caiiesccns Reut. ; smaller and more 

 slender, more yellowish in color and marked with a fuscous 

 vitta following the claval suture; the male genitalia very dis- 

 tinctive. Length 6^ mm. 



Male : Head oblique, produced beyond the eye for a space equal to two- 

 thirds the length of the eye ; front and clypeus tumidly prominent, leaving 

 a deep sinus at base of clypeus ; cheeks tumidly raised, almost tuberculate ; 

 vertex nearly flat, a little wider than the eye viewed from above. Antennae 

 long; segment I as long as head and pronotum together, moderately 

 clothed with long pale hairs and a few stiff bristles ; II not quite twice 

 the length of I; III and IV together shorter than II. Pronotum twice 

 wider than long, with prominent humeri. Elytra parallel, twice longer to
