NEW AMERICAN CYNIPIDS FROM GALLS—WELD 13 
ANDRICUS STRAMINEUS, new species 
Female.—Uniform light amber or with infuscations on thorax and 
occiput. Head granulate; from above transverse, cheeks broadened 
behind eyes, occiput not concave; from in front interocular area 
higher than broad, malar space one-fourth eye, faint striae about 
mouth, antennae 15-segmented, filiform, segments as (scape) 16:8: 23 
(4.5) :21:17:16:14:12:10:9:9:8:8:7:18 (5). Sides of pronotum 
bulging in front of tegulae, pubescent. Mesoscutum coriaceous, 
shining, with short appressed pubescence without evident punctures, 
parapsidal grooves narrow, deep, smooth, percurrent; disk of scutel- 
lum coriaceous back of the narrow, smooth, oblique pits, rugose be- 
hind, pubescent. Carinae on propodeum straight and parallel. 
Mesopleura in part with faint striae. Wing pubescent and ciliate, 
veins brown, first abscissa of radius angulate, areolet reaching one- 
fifth and cubitus three-fourths way to basal. Claws with a strong 
tooth. Abdomen longer than head plus thorax, as high as long, lengths 
of tergites along dorsal curvature as 47: 18:8: 15:9: 12, II with pubes- 
cent areas on sides at base, III and LV punctate. Ventral spine in 
side view three times as long as broad, from below triangular. Sheaths 
_ projecting at tip. Ovipositor stout, straight at tip. With the width 
of the head used as a base, the length of mesonotum ratio is 1.3; an- 
tenna 2.6, wing 3.6. Lengths of the four specimens 2.1, 2.5, 2.8, and 
2.95 mm. 
Types.—U.S.N.M. No. 563882: Type. Paratypes in the Chicago 
Museum of Natural History and the California Academy of Sciences. 
Gall (pl. 2, fig. 15) —A tan-colored, bare, smooth, ellipsoidal gall, 
bursting out of the bark along the internodes of small twigs, drawn 
out to a blunt point at apex, 2 by 3 mm. by 3 mm. high, single or in 
small groups in fall. Contains a single larval cell with a wall 0.2 mm. 
thick. 
 Host—Quercus oblongifolia. 
Habitat—Mrs. N. W. Capron collected galls containing pupae 
on February 4, 1935, at Nogales, Ariz. One adult was cut out of the 
gall on February 14 and three emerged on March 5. She collected 
galls also at Young, Ariz., on an undetermined oak. Galls have been 
seen at Patagonia, Ariz. 
ANDRICUS VERNUS, new species 
Female.—Red; head and tips of antennae and of ventral valves 
darker. Head from above transverse, as broad as thorax, cheeks 
broadened behind eyes, occiput concave; from in front broader than 
high, malar space 0.5 eye with radiating ridges from corners of clypeus, 
face pubescent, punctured, front coriaceous, antennae 13-segmented, 
lengths as (scape) 15(8) : 9: 20(5) :19:16: 14: 11:10:9:9:9:9:16(6).
