Vol. XI] VAN DUZEE—NEW SPECIES OF ANTHOCORIDAZ ]4j 



apex. Surface clothed with soft whitish pubescence, longer on pronotum and 

 elytra, nearly or quite wanting on base of head, pleural pieces and base of 

 ventral segments; head with six stiff bristles. 



Color, piceous black; pronotum, excepting the region of the callosities, and 

 the elytra castaneous brown ; membrane smoky, a large basal spot emphasized 

 at apex of cuneus and the borders of the veins nearly to their apex, pale. 



Described from 36 examples taken by me from Pinus 

 albicaulis at an altitude of 9,100 feet on top of Mt. Eddy, 

 Siskiyou Co., Calif., July 28, 1918. No males or immature 

 individuals were seen. The Academy also possesses a series 

 taken by me at Huntington Lake, Fresno Co., Calif., in 

 July, 1919, at an altitude of 7,500 feet, three taken by Mr. 

 C. L. Fox at Dry Lake Lookout Station near Walker, Siski- 

 you Co., Calif., June 1, 1920, at 7,000 ft. elevation, and one 

 taken by me at the Biological Station near Nanaimo, Van- 

 couver Island, June 28, 1920, all females. This species 

 seems to be quite typical of the genus Tetraphleps, and 

 occurs only on pine so far as my experience goes. I would 

 distinguish this genus primarily by the punctate elytra and 

 form of the ostiolar canal. The membranal veins seem al- 

 ways to be prominent. 



Holotype, female, No. 794, Mus. Calif. Acad. Sci. 



Type locality, top of Mt. Eddy (altitude 9,100 ft.), 

 Siskiyou Co., Calif. 



6. Tetraphleps furvus, new species 



Closely allied to latipennis, a little narrower and more 

 polished with the elytra of a paler and more testaceous 

 brown. Length 4 mm., width \ x / 2 mm. 



Head narrower and flatter between the ocelli than in latipennis, the apex 

 slightly notched either side the tylus. Antennae longer and more slender; 

 seg. I slightly surpassing the head; II as long as the entire head; III fully 

 equal to IV in length and somewhat thinner. Rostrum slightly surpassing 

 anterior coxae; prosternum more flattened with margins more prominent than 

 in latipennis; mesosternum less strongly aciculate on sides, ostiolar canal as 

 in allied species. Pronotum more transverse, sides nearly rectilinear, a little 

 rounded at anterior angles, slenderly carinate ; region of callosities scarcely 

 elevated; surface closely, obscurely punctate. Elytra parallel, costa subsinuate, 

 veins less distinct and the punctures more distant and obscure than in lati- 

 pennis; membrane longer, exceeding abdomen by about half its length, outer 

 veins less abruptly curved, the inner less prominent; surface with obscure 

 transverse wrinkles which become longitudinal at apex. Whole surface of 

 body clothed with a pale pubescence, more highly polished than in latipennis.
