NEW AMERICAN CYNIPIDS FROM GALLS—WELD 21 
CALLIRHYTIS LUPANA, new species 
Female—Head, pronotum, mesoscutum, and front legs reddish 
brown, rest of body darker. Head from above transverse, as broad 
as thorax, vertex coriaceous, cheeks broadened behind eyes, occiput 
concave; from in front broader than high, malar space one-third eye, 
radiating ridges from corners of clypeus, face granulate, antennae 
13-segmented, lengths as (scape) 7 (4): 5:8(2):7:7:6:6:5:5:5:5:- 
5:10(4). Sides of pronotum finely rugose. Mesoscutum bare, coria- 
ceous, slightly rugose behind, parapsidal grooves percurrent, sculp- 
tured, anterior parallel lines smooth, distinct. Scutellar groove with 
fine longitudinal ridges, disk distinctly rugose, margined behind. 
Median area of propodeum with several longitudinal ridges. Meso- 
pleura bare, faintly striate anteriorly. Wing hyaline, pubescence short, 
brown, margin nonciliate (under high power very short cilia on hind 
margin), veins brownish, first abscissa of radius arcuate, not clouded, 
radial cell shghtly open at base and apex, areolet reaching one-eighth 
way to basal, cubitus reaching basal. Tarsal claws weak, simple. Ab- 
domen about equal to head plus thorax, Jength to height to width as 
67:63:42; lengths of tergites along dorsal margin as 30:11:12:7:5, 
sides of II almost bare, a few hairs on VII, exposed parts of III-VI 
coriaceous. Ventral spine 3 times as long as broad in side view. Ovi- 
positor very long. With width of the head used as a base, the length 
of mesonotum ratio is 1.0, antenna 1.6, wing 3.4. Length 1.35-1.9 mm. 
Average of 17 specimens 1.70 mm. 
Male—Uniform dark brown, antennae and legs lighter, antennae 15- 
segmented. Mesonotum coriaceous. Wing pubescent and _ ciliate. 
Abdomen half as long as head plus thorax. Length 1.15-1.3 mm. 
Average of five specimens 1.23 mm. 
Callirhytis flora Weld, producing a similar gall on Q. wislizenii, is 
distinguished by its larger size, relatively longer antennae, heavier 
cross veins, larger areolet, and disk not margined behind. 
Lypes.—U.S.N.M. No. 56390: Type female, allotype, and four female 
paratypes. Paratypes in the Chicago and American Museums of Nat- 
ural History and the California Academy of Sciences. 
Host.— Quercus emoryt. 
Gall (pl. 2, fig. 19) —A rather abrupt fusiform polythalamous en- 
largement on the underside of the midrib, stunting the development of 
the leaf. June. 
Habitat—The type material was collected on June 28, 1935, at 
Wolf Creek Camp, 10 miles from Prescott, Ariz., by Mrs. N. W. 
Capron. Adults were then emerging. She later sent empty galls 
from Cherry, Young, and Nogales, Ariz. <A similar gall occurs on 
Q. hypoleuca at Patagonia, Ariz.
