24. Phytocoris sagax, new species 



Allied to commissuraUs ; head and pronotum anteriorly yel- 

 lowish; pronotum margined and elytra maculated with fus- 

 cous; membrane irrorate. Length 7 mm. 



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

 greatest width of the eye ; front moderately convex ; clypeus broad, prom- 

 inent. Antennae long; segment I as long as head and pronotum together 

 when seen from above; II as long as costal margin of corium; III one half 

 of II ; IV a little longer than pronotum. Pronotum twice wider than long, 

 somewhat polished; elytra nearly parallel; hind femora (female) six times 

 as long as wide, its tibial spines long. Upper surface clothed with black 

 decumbent hairs and flattened white tomentum; rostrum reaching middle of 

 venter. Genital segment small ; sinistral notch deep ; sinistral clasper small 

 with a dorsal angle some ways from the base; forming a blunt tubercle; 

 tip of the clasper hidden beneath the apex of the segment ; dextral clasper 

 very long, broad and flattened at base, its truncate apex curved so as to 

 almost meet the dorsal angle of the sinistral notch. 



Color testaceous white ; head and middle of anterior margin of pronotum 

 more yellowish, varied with ferruginous ; sides of pronotum anteriorly and 

 inferiorly black, marked with a white point behind the eye; hind margin 

 with an even black vitta before the white edge. Scutellum with a black 

 point either side before the apex. Elytra fuscous, opaque ; clavus, base of 

 corium, a large spot on the middle extended along the costa to apex and 

 an angular spot at apex of the corium polished whitish, inner edge of 

 cuneus varied with black; membrane blackish, irrorate more or less with 

 white, forming a white spot at apex of the areole. Beneath mostly pale 

 with the pectoral pieces largely black, the coxae white. Legs pale, the femora 

 marmorated with fuscous at apex, on anterior pair interrupted by a pale 

 longitudinal line on either side; tibial spines long, brown, on brown dots, 

 the apex of the tarsi infuscated. Basal segment of antennae black dotted 

 with white; II fuscous at base and apex, brownish on the middle, base 

 rather broadly white; III brown, white at base; IV brown. Female a little 

 broader than the male and more clearly marked in the type.

Large, elongate-ovate ; pale yellowish white ; vertex with a 

 large polished black spot; posterior vitta of pronotum and 

 lineations on elytra black. Length 8^ mm. 



Female : Head oblique ; produced beyond the eye for a space greater than 

 the length of the eye ; eyes seen from above ovate. Antennae long ; segment 

 I as long as basal width of pronotum, slightly thickened to the base ; II as 

 long as costal margin of corium; III one fourth longer than I ; IV a little 

 longer than the pronotum. ; Pronotum less narrowed anteriorly than usual, 

 as long as the head viewed from above, its anterior margin about one half
