129. Dicyphus criidiis Van D. Fallen Leaf Lake. August

130. Strongylocoris atratus (Uhl.) San Mateo Co., June 

 20, 1917; Santa Cruz Co., June 7, 1917; Niles Canyon, May, 

 1916; Contra Costa Co., June 14, 1917. The series taken by 

 Mr. Giffard exhibits considerable tendency to variation in the 

 color of the legs. 



131. Philophorus clavatiis (Linn.) Near Stockton, May 30, 

 1917. 



132. Ccratocapsus fasciatus (Uhl.) Placer Co., August 20, 

 1916; Donner Lake, August 24, 1916. 



133. Ccratocapsus fusiformis, new species 



Aspect of modestus but smaller with the apical two antennal segrments 

 thicker, fusiform ; color castaneous to piceous. Length 4 mm. 



Head nearly vertical ; hind margin of vertex flat or slightly rounded, 

 not sharp as in the Pilophoraria, but with the eyes cut off nearly straight 

 behind and in this character approaching that division. Front convex, 

 opaque, with indications of a longitudinal groove and oblique lateral striae; 

 clypers narrow, prominent, polished and distinct from the front ; gala 

 short, horizontal. Antennae short ; first segment scarcely three times as 

 long as thick, not surpassing the tip of the head; second when pressed 

 back about attaining the base of the pronotum, gradually thickened from 

 base to apex where it equals the first in diameter; third and four together 

 about equal to the second and slightly thicker than its apex, fusiform, the 

 third a little longer than the fourth. Pronotum about as in modestus but 

 rather more convex posteriorly ; its surface scarcely polished, closely, 

 minutely punctate ; sides rectilinear. Scutellum and elytra closely and 

 roughly punctate, the latter ni the male a little widened posteriorly and 

 very slightly constricted near the base ; in the female broader and more 

 constricted. Legs shorter than in modestus. Whole upper surface clothed 

 with stiff subappressed fuscous hairs. 



Color dull castaneous or piceous ; darkest on the head, base of the 

 pronotum', disk of the corium and cuneus ; often paler and tinged with 

 testaceous on the clavus. Antennae piceous, the basal segment paler. Pec- 

 tus and anterior and intermediate legs often paler or almost testaceous; 

 hind legs piceous, the knees, tip of the tibiae and the tarsi paler. 



Male genitalia complicated as always in this genus ; the dextral hook 

 bifurcate from its base, the dorsal branch porrect, slender and acute ; 

 the ventral broad, curved downward along the margin of the segment, its 

 apex recurved and bifurcate, the apical spine slender and acute, the sub- 

 apical lateral, broad, flattened at base and very acute at apex ; sinistral 

 hook broadly forked from its base, the dorsal branch short, obtuse, the 

 ventral slender and acute, curved upward under the bifurcated apex of the 

 ventral branch of the dextral hook.
