﻿AMERICAN CYNIPID GALL WASPS — WELD 329 



Abdomen as long as head plus thorax, as high as long, all tergites 

 showing on dorsal margin. Ventral spine slender, longer than hind 

 metatarsus. Using width of the head as a base the length of mesono- 

 tum ratio is 1.3 ; antenna 2.o ; wdng 3.8. Length 2.3-2.6 mm. Aver- 

 age of three specimens 2.48 mm. 



Differs from A. foliatus (Ashmead) in the shorter and more sparse 

 pubescence on thorax and in having a distinct areolet. 



7Vi9e.— U.S.N.M. No. (10115 : Type. Paratype in C.A.S. 



Host. — Quercus lobata. 



Gall (pi. 16, fig. 6). — A smooth, bare, ovoid bud gall found in fall 

 in the axils of leaves, greenish and mottled with purple, projecting 

 beyond the bud scales, 2-3 mm. in diameter. 



Habitat. — The types were cut out November 10, 1949, from galls 

 collected at Chico, Calif., on October 18, 1948. Galls have been seen 

 at Stanford University, Los Gatos, Santa Margarita, Lakeport, Ukiah, 

 and Willits, Calif. 



ANDRICUS PROJECTUS, new species 



Femule. — Body reddish brown, infuscated dorsally; antennae and 

 legs lighter. Head coriaceous; from above transervse, occiput not 

 concave, cheeks broadened behind ej^es; from in front broader than 

 high, interocular space broader than high, malar space one-half eye, 

 a few striae from corners of clypeus, antennae filiform, 13-segmented. 

 Mesoscutum pebbled, almost bare, parapsidal grooves pcrcurrent, no 

 median. Disk of scutellum pubescent, rugose except back of septum, 

 foveae smooth, shallow. Mesopleuron and sides of propleura bare, 

 finely striate. Wing hyaline, hairs on surface short, not ciliate, veins 

 almost clear, areolet small, radial cell five times as long as broad. 

 Claws with a strong tooth. Cariiiae on propodeum straight, parallel. 

 Abdomen longer than head plus thorax, lengths of tergites along 

 dorsal curvature as 44:11:2:2:9; hind margin of II smooth, ex- 

 posed parts of rest punctate. Ventral spine slender, seven or eight 

 times as long as broad. Using width of head as a base, the length of 

 mesonotum ratio is 1.3 ; antenna 2.5 ; wing, 4.5 ; ovipositor 3.4. Range 

 in length 1.15-3.0 mm. Average of nine specimens 2.12 mm. Differs 

 from A. niger Tavares in having tergite III punctate. 



Types U.S.N.M. No. 60116: Type and one paratype. Paratypes 

 also in C.A.S. and A.N.S.P. 



Host. — Quercus chi'ysole'pis. 



Gall (pi. 16, fig. 8). — Bursting out far beyond the bud scales in the 

 fall, cylindrical, bare, smooth, greenish with a light tan apex. When 

 detached the base is darker, with a depressed scar at the truncated 

 end, 7.0 mm. long by 2.1 mm. in diameter. Monothalamous. Usually
