linear, delimited by a row of punctures; explanate margins straight, narrow 

 except across the constriction; hind margin broadly excavated. Scutellum 

 broader than in obscurus: elytral punctures smaller than is usual; membrane 

 complete. Anterior femora strongly incrassate, subsulcate beneath, the an- 

 terior edge armed with two large teeth, the apical the larger, and about 

 three small ones either side the apical ; anterior tibiae much curved, armed 

 with three teeth on the expanded apex, followed basally by about six small 

 ones; hind tibiae armed with numerous long erect stiff pale hairs. 



Color, piceous black, becoming paler or more castaneous on antennae, ros- 

 trum and legs, and slightly so on elytra, incisures of first antennal segment 

 and base of second and third segments; tibiae and tarsi honey-yellow; margin 

 of pronotum for a space at middle and narrow costa to beyond tip of scutellum 

 whitish; extreme tip of scutellum and spot on membrane at apex of corium 

 pale. 



Female: Brachypterous, darker, more roughly punctured, especially on 

 anterior lobe of pronotum. 



Described from one male taken by Dr. E. C. Van Dyke, 

 July 24, 1910, at Paradise Valley, Kings River Canyon, 

 Fresno Co., Calif., at an elevation of 7,000 feet, one female 

 taken by Dr. Van Dyke on Cypress Ridge, near Fairfax, 

 Marin Co., Calif., May 29, 1920, and another female taken 

 by the writer at Fairfax, May 11, 1919. This is a much 

 larger species than, and very different looking from, the 

 eastern ferus, our only other species having the hind tibiae 

 setose in both sexes. 



Holotype, male, No. 758, and allotype, No. 759, Mus. 

 Calif. Acad. Sci.; a paratype also in the Academy collection. 



Type locality, Paradise Valley, King's River Canyon, 

 Fresno Co., Calif. 



7. Eremocoris dimidiatus, new species 



Allied to ferus but larger and more parallel in form; 

 elytra castaneous-brown with base abruptly pale. Length 

 7mm. 



Head shorter than in ferus, minutely punctured either side beyond eye9; 

 segment II of antennae nearly twice as long as I; III three-fourths of II, 

 IV a little shorter than III; rostrum reaching middle of metasternum, seg- 

 ment I just passing base of head, II shorter than III and IV together. Pro- 

 notum about as long as its humeral width; sides parallel with anterior angles 

 rounded; constriction near basal fourth; anterior lobe polished, impunctate, 

 strongly convex; collum narrow, linear, strongly differentiated by a line of 

 punctures; posterior lobe flat, coarsely punctured; expanded sides rather 

 broad. Scutellum long, depressed, remotely punctured and transversely 

 wrinkled. Clavus with usual four rows of punctures, the second broken and 

 connate with third at base; membrane reaching tip of abdomen in type; 

 Carinate posterior margin of prosternum forming an angle or obtuse carina 

 across base of median tooth which is much bent inward between anterior
