NEW AMERICAN CYNIPIDS FROM GALLS—WELD hk 
rinae on propodeum diverging below, enclosed area bare, smooth, 
shining. Abdomen longer than head plus thorax, length to height 
to width as 63:55:35; lengths of tergites along dorsal curvature as 
28:15:14:11:10:5, ventral valves protruding obliquely, ventral 
spine seven times as long as broad in side view, pubescent below, 
shorter than hind metatarsus. Using width of head as a base the 
length of mesonotum ratio is 1.86; antenna 2.4; ovipositor 4.9; wing 
4.6. Range in length of 21 specimens 1.7-2.6 mm. Average 2.2 mm. 
Differs from the described species of the genus in having the cheeks 
broadened behind the eyes. 
Types.—U.S.N.M. No. 56376: Type and five paratypes. Paratypes 
in the American and Chicago Museums, Museum of Comparative Zo- 
ology, Academy of Natural Sciences of Philadelphia, and California 
Academy of Sciences. 
flost.—Quercus alba. 
Gall—Solitary, sessile, on underside of leaf close to edge in Octo- 
ber, shaped like an old-fashioned straw beehive, white or pinkish, 
measuring up to 4.6 mm. broad by 4.0 mm. high. Inside is a large 
cavity with a transverse larval cell at very base. During the winter 
on the ground the outer fleshy layer shrivels and the gall becomes 
more cylindrical (pl. 1, fig. 9). Not common. 
fabitat.—The type is from a series of 16 that were found alive in 
out-of-door breeding cage on March 7, 1942, from galls collected at 
Hast Falls Church, Va., in October 1940. In galls collected at Vienna, 
Va., in October 1938 living adults were found the next October and 
one emerged on February 12, 1940, and others had emerged and died 
in the cage by April 15. Galls have been seen at Bluemont and Ross- 
lyn, Va., Cabin John, Md., and Washington, D. C. 
Genus TRIGONASPIS Hartig 
TRIGONASPIS PULCHELLA (Beutenmuclier) 
Dryophanta pulchella BEUTENMUELLER, Ent. News, vol. 22, p. 357, 1911. 
Described from two specimens of which the one from Catalina 
Island Beutenmueller considered as the type. Both go in Trigonaspis. 
Genus ANDRICUS Hartig 
ANDRICUS BRACTEATUS, new species 
Female.—Light reddish brown. Head from above transverse, not 
so broad as thorax, cheeks broadened behind eyes, occiput concave; 
from in front broader than high, malar space one-third eye without 
striae, interocular area 1.2 times as broad as high, antenna 14-seg- 
mented, lengths as (scape) 16: 9: 24(5) :21:20:17:16:11:10:10:9:8:
