ART. 10 GALL-INHABITING CYNIPID WASPS WELD 37 



DISHOLCASPIS CONALIS, new species 



Female. — Pale yellowish-red. Whole body densely covered with 

 short silky yellowish-white pubescence except on vertex and a star- 

 shaped dorsal spot on second terf:^ite. Head coriaceous; from above 

 narrower than thorax, cheeks greatly broadened behind eyes, occiput 

 not concave: from in front facial quadrangle 1.2 times as broad as 

 high, malar space one-third eye without groove, antenna 14-seg- 

 mented, filiform, lengths as (scape) 14 : 9 : 27 : 22 : 17 : IG : 14 : 

 12 : 10 : 10 : 9 : 8 : 7 : 15. Sides of pronotum smooth. Mesoscutum 

 broader than long, broadly rounded in front, coriaceous with setig- 

 erous punctures, parapsidal grooves deep, smooth, reaching forward 

 halfway, no median, anterior and lateral lines slightly darker. Scu- 

 tellum with transverse groove at base, disk broader than long, rugose 

 behind. Neck of propodeum rugose and above it are fragmentary 

 carinae. Mesopleura smooth. Tarsal claws with a tooth. Wing 

 slightly dusky, pubescent, ciliate, veins brown, first abscissa of radius 

 angulate with a slight cloud above angle, free portion of subcosta 

 reaching about halfway to margin, areolet reaching one-fifth way to 

 basal. Abdomen as long as head and thorax, length of tergites along 

 dorsal margin as 38:10:2, hind margin of second at angle of 45°. 

 ventral spine short, broad, hairy, sides parallel with triangular apex, 

 gouge-shaped in cross-section; ovipositor short, straight at tip. 

 Using width of head as base the length of mesonotum ratio is 1.6, 

 antenna 2.4, ovipositor 2.3, wing 4.3. Length, 2.8-4.4 mm. Aver- 

 age of 30 specimens, 3.65 mm. 



This would run in Dalla Torre and Kiefi^er key to Gynips on 

 account of the pubescent abdomen but with this exception it has 

 the characters of DlshoJcaspis. 



Type.—Q^i. No. 27195, U.S.N.M. Type and 12 paratypes. Para- 

 types in American Museum, Field, and Stanford. 



Host. — Quercus garryana. 



Gall (fig, 37). — Conical, 10-18 mm. high, with a clasping base 8-12 

 mm. in diameter, the tapering apex often lopsided, single or in 

 small clusters on small twigs in the fall. Greenish when growing 

 and covered Avith dense short white pubescence which rubs off after 

 the galls begin to harden. They start to develop late in May and 

 mature in September. Old galls are tan-colored. The interior 

 consists of dense cellular tissue with a transversely placed larval 

 cell, not separable and without a distinct lining wall. 



Habitat. — The type material was collected September 8, 1922, in 

 Sequoia National Park, Calif., just above the Cedar Creek checking 

 station on the road from Kaweah to Giant Forest. Some flies issued 

 and died in the packet before October 1, while others died inside, not 

 beinir able to chew out of the hard calls.
