anterior parallel and lateral lines not evident, no median. Disk of 
scutellum smooth back of the two deep, smooth pits, reticulate behind, 
margined at sides and behind. Carinae on propodeum converging 
above. Mesopleura bare, smooth. Wing subhyaline, pubescence and 
cilia dark, veins brown, heavy, first abscissa of radius arcuate, clouded 
anteriorly, one-eighth as long as second which is nearly straight, 
areolet reaching one-fifth way to basal, cubitus nearly from basal to 
margin. Tarsal claws toothed. Abdomen about as long as head plus 
thorax, longer than high, lengths of tergites along dorsal curvature as 
40:18:17:14:7:6, pubescent patches on sides of If at base. Ventral 
spine seven times as long as broad in side view, shorter than hind 
metatarsus. With width of the head used as a base, the length of 
mesonotum ratio is 1.3, antenna 2.8, wing 4.3, ovipositor 2.5. Length 
of five specimens 1.6-2.15 mm. Average 2.05 mm. Runs in the Ash- 
mead 1903 key to Liodora. Differs from genotype in its light color, 
larger areolet, longer radial cell, smoother disk, and bent carinae. 
Hardly to be distinguished from sesszlis Weld whose gall is quite dif- 
ferent in structure. 
Types.—U.S.N.M. No. 56375: Type. Paratypes in the American 
and Chicago Museums of Natural History and the California Academy 
of Sciences. 
Host.—Quercus oblongifolia. 
Gall (pl. 1, fig. 3) —A spangle-gall sessile on veins on underside of 
leaf late in fall, 24 mm. in diameter, fleshy, pinkish, covered with 
stellate hairs on its sticky surface, the edge inrolled, the larval cell 
basal and eccentric. One to four on a leaf. 
Habitat.—Mrs. N. W. Capron collected galls containing white pupae 
on January 21, 1935, at Nogales, Ariz. Adults emerged on February

LIODORA APIARIUM, new species 
Female.—Black; mandibles and knees brown. Head finely coria- 
ceous; from above transverse, almost as broad as thorax, occiput con- 
cave, cheeks broadened behind eyes; from in front broader than high, 
interocular area broader than high, malar space 0.28 eye without 
striae, face pubescent below antennae. Antennae 14-segmented, 
lengths as (scape) 13:6:17:14:138:12:10:9:8:7:7:7:6: 7, last eight 
with rhinaria. Sides of pronotum pubescent, striate in part. Meso- 
scutum mostly bare, smooth, shining, grooves deep, narrow, percur- 
rent, anterior and parallel lines not evident, no median. Disk of 
scutellum smooth, pubescent, margined, with two shallow, smooth 
pits at base. Mesopleura mostly bare, smooth, shining. Hind tibia 
longer than tarsus; claws toothed. Wing pubescent and ciliate, veins 
brown, first abscissa of radius angulate, radial cell elongated, areolet 
reaching one-sixth way to basal, cubitus almost reaching basal. Ca-
