NEW AMERICAN CYNIPIDS FROM GALLS—WELD 23 
allel ridges on sides of pronotum. Mesonotum bare, coriaceous, 
slightly rugose in low relief posteriorly between grooves. The latter 
percurrent, broader behind. Anterior and lateral lines distinct, nar- 
row. A faint trace of a median behind. Mesopleura bare, coria- 
ceous. Scutellum rugose, the sculptur ed transverse groove at base with 
but an indistinct septum, disk margined behind. Carinae on propo- 
deum parallel. Wing hyaline, veins pale, cross veins not clouded, 
pubescence short, margin nonciliate. Abdomen about equal to head 
plus thorax, all tergites visible on dorsal curvature and each with a 
broad coriaceous band posteriorly, base of II bare, ventral spine not 
projecting beyond lobes of hypopygium. ‘Tarsal claws simple. 
Using the width of the head as a base the length of mesonotum ratio 
is 1.2, antenna 1.7, wing 3.4, ovipositor 2.2. Range in length of 150 
specimens 1.85-3.0 mm. Average 2.29 mm. Closely related to 
C. lupana of present paper, a sexual generation from a midrib swell- 
ing on same host, emerging late in June. 
Types—U.S.N.M. No. 56392: Type and 45 paratypes. Paratypes 
in the American and Chicago Museums of Natural History, Museum 
of Comparative Zoology, Academy of Natural Sciences of Philadel- 
phia, and California Academy of Sciences. 
TTost.—Quercus emoryt. 
Gall (pl. 1, fig. 7) —A flattened brown mass of 3-10 cells inside 
the acorn beside the much-reduced cotyledons, the number of cells evi- 
dent on the surface. Masses measure up to 10 mm. long. 
Habitat.—The type is selected from a series bred from acorns from 
Santa Ana, Sonora, Mexico, taken from baggage at quarantine 
at Nogales, Ariz., on September 28, 1935 (No. 10348). Adults 
issued on April 10, 1937, April 2, 1938, April 3, 10, 15, 1989, April 7, 
17, 1940, April 7, 12, 1941, April 12, 15, 1942, and April 16, 1943. Para- 
types are from Hermosillo, Magdalena, and other points in the state 
of Sonora. Earliest emergence was March 10. Galls from Cusion, 
Cuchuta, Esqueda, Guaymas, Fronteras, and Nogales (all in Sonora) 
have been found in “bellotas” in the personal baggage of Mexicans 
crossing the border. Over 60 lots have been intercepted, mostly at 
Nogales, Ariz., a few at Naco and Douglas, Ariz., and a few at El Paso 
and Ysleta, Tex. 
CALLIRHYTIS UVELLAE, new species 
Female.—Reddish brown, legs and antennae yellow. Head trans- 
verse, broader than thorax, shagreened; from above not broadened 
behind eyes; from in front malar space about one-fourth eye without 
groove or striae, antenna 14-segmented, segments as (scape) 11 (6): 
6:16(3) :12:10:10:9:9:8.5:8:7:7:7:9 (4.5). Mesoscutum longer 
than broad, bare, microcoriaceous, parapsidal grooves percurrent, an-
