CALLIRHYTIS PERRUGOSA, new species 
Female—Head and thorax yellowish brown, abdomen reddish 
brown. Entire head and thorax almost uniformly rugose but not so 
coarsely so as in Amphibolips. Head as broad as thorax, interocular 
space broader than high, cheeks strongly broadened behind eyes, 
occiput from above concave. Antennae 14-segmenied, lengths as 
(scape). 20/9): 102206) 1412 11 1O10E 90 9n Sh) (a8s eearalp= 
sidal grooves scarcely visible in the sculpture, median slightly visible. 
Scutellum longer than broad, foveae deep, sculptured, septum broad. 
Area between carinae on propodeum rugose. Wing with yellowish 
tinge, margin not ciliate, surface short-pubescent, veins yellowish 
brown, areolet reaching one-eighth way to basal. Abdomen with 
triangular pubescent patches on sides at base, longer than high, lengths 
of first two tergites as 27:6. Ventral spine in side view three times 
as long as broad. With width of head used as a base, the length of 
mesonotum ratio is 1.36; antenna 2.1; ovipositor 1.9; wing 3.5. Length 
of 89 measured specimens 3.3-5.1 mm. Average 4.1 mm. 
Related to the species in this genus reared from root galls but dit- 
fering from them all in the very rugose mesonotum in which parap- 
sidal grooves are not distinct even in part. 
Types.—U. 8. M. M. No. 56391: Type and seven paratypes. Para- 
types in the American and Chicago Museums of Natural History, 
Museum of Comparative Zoology, Academy of Natural Sciences of 
Philadelphia, and California Academy of Sciences. 
Host.— Quercus alba. 
Habitat.—The type is selected from a series of over 50 specimens 
collected at East Falls Church, Va., in seven different years at dates 
from April 138 to May 3. They were taken while ovipositing in the 
topmost buds of 3-6-foot saplings or strong sprouts from stumps of 
white oak, but attempts to determine the resulting gall have so far 
failed and so have attempts to find the gall from which these flies 
must have just emerged. Paratypes are from Washington, D. C., 
Great Falis, Md., Malaga, N. J., and Castle Rock and State College 
(May 7), Pa. 
CALLIRHYTIS SONGRAE, new species 
Female.—Black, with reddish brown on base of antenna and on 
more or less of head, mesonotum and side of pronotum. Head cori- 
aceous; from above transverse, as broad as thorax, occiput concave, 
cheeks distinctly broadened behind eyes; from in front broader than 
aigh, interocular area 1.3 times as broad as high, malar space 0.4 eye 
with distinct groove. Antennae 13-segmented, lengths as (scape)
