Vol. XI] VAN DUZEE—NEW SPECIES OF ANTHOCORIDAZ 



139 



3. Anthocoris dimidiatus, new species 



Allied to nigripes; polished black, second antennal seg- 

 ment, except its apex, and legs, castaneous; elytra yellowish 

 testaceous as far as apex of clavus; basal half of membrane 

 white; corium entirely opaque or subopaque. Length 3 mm. 



Head as long as pronotum and basal lobe of scutellum combined, its length 

 before the ocelli a little greater than width across the eyes; sides parallel 

 to a point nearly one-half distance from front of eye to apex, then suddenly 

 constricted and again somewhat expanded at tip; this character, common to 

 all allied species, is more pronounced here. Antennae slender, as long as 

 head, pronotum and scutellum as far as the transverse depression; basal 

 segment not attaining apex of head; II as long as head; III and IV subequal, 

 fusiform, a little thinner than II. Rostrum reaching to middle of mesoster- 

 num; seg. I attaining anterior line of eye; II touching anterior coxa;. Pros- 

 ternum deeply impressed across the middle; sides sinuated, the carinate edges 

 not encroaching upon the collum; surface minutely rastrate punctate, the 

 prominent callosities nearly smooth. Posterior lobe of scutellum minutely 

 rastrate. Elytra subopaque over their whole surface, the thickened apical 

 margin of the cuneus only polished; membranal veins moderately and about 

 equally prominent, the inner pair scarcely approaching at base, the outer a 

 little arcuate. Venter very minutely rastrate with base of segments polished. 



Color, deep black; femora, apex of second antennal segment and the third 

 and fourth piceous brown; basal two thirds of second antennal segment and 

 tibiae honey-yellow. Elytra yellowish white as far as tip of clavus, becoming 

 black beyond that point, with a pale mark on the thickened apex of the 

 embolium; basal half of membrane milky white, the apical blackish; surface 

 clothed with a few soft pale hairs. 



Described from one female taken by me on the Felch 

 Ranch, near Cayton, Calif., July 15, 1918. The long an- 

 tennae would seem to ally this species with sylvestris, but the 

 opaque elytra and distinct membranal veins indicate closer 

 relationship with nigripes, and will serve to distinguish it 

 from whitei which it slightly resembles. With the type were 

 taken two immature females, one winged but teneral, the 

 other a nymph with the abdomen broad oval and the elytra 

 short, attaining middle of third tergal segment, black with 

 the scutellar margin of clavus castaneous, base of corium 

 and embolium and narrow membrane white. 



Holotype, female, No. 791, Mus. Calif. Acad. Sci. 



Type locality, Felch Ranch, near Cayton, Shasta Co., 

 Calif. 



4. Lyctocoris doris, new species 



Allied to campestris and belonging to that section of the 

 genus; more elongated and darker in color; piceous-black
