ANDRICUS FURNESSULUS, new species 
Female——Reddish brown, with black markings on thorax and dorsal 
abdomen. Head from above transverse, finely rugose, not quite so 
broad as thorax, cheeks broadened behind eyes; from in front broader 
than high, malar space one-third eye with radiating ridges, antennae 14- 
segmented, lengths as (scape) 13(6) :8:20(4) : 16:18:18: 12:12:10: 
9:8:7:7:14(5). Sides of pronotum pubescent, with parallel ridges. 
Mesoscutum very finely rugose, coarser posteriorly, anterior parallel 
and lateral line areas black, parapsidal grooves percurrent but deeper, 
smooth, and wider posteriorly, no median. Foveae narrow, shining, 
oblique, disk coarsely rugose. Carinae on propodeum arcuate. Meso- 
pleura pubescent, entirely covered with parallel ridges. Tarsal claws 
toothed. Wing hyaline, pubescent, ciliate, veins brown, first abscissa 
of radius slightly clouded, radial cell slightly open at base, tip of radius 
slightly bent at margin, areolet reaching one-fifth way to basal, cubitus 
reaching basal. Abdomen nearly as long as head plus thorax, length 
to height to width as 30: 23: 21, lengths of tergites along dorsal margin 
as 24:7, tergite II entirely aciculate, III finely rugose with confluent 
punctures, ventral spine in side view about three times as long as broad. 
Using width of head as a base the length of mesonotum ratio is 1.4, 
antenna 2.5, wing 3.8, ovipositor 3.0. Length 2.65-3.15 mm. Average 
of 20 specimens 2.86 mm. 
Related to Andricus furnessae (Weld) from a similar but larger 
gall in Michoacan, Mexico, but differing in its smaller size, parti- 
colored thorax without median groove, and in the aciculate second 
tergite. 
Types.—U.S.N.M. No. 56381: Type and four paratypes. Paratypes 
in the California Academy of Sciences and the Chicago and American 
Museums of Natural History. 
Gall (pl. 2, fig. 10)—A woolly mass partly or entirely encircling 
small twigs, measuring up to 30 by 25 mm., pure white or rosy when 
young, consisting of a large number of separate biconical cells attached - 
at a common point, each covered with long hairs. ‘These measure 
about about 7 by 5 mm., shorter and broader than in furnessae. 
FT ost.— Quercus eon gifolia. 
Habitat.—The type is selected from a series from a ell sent from 
Nogales, Ariz., by Mrs. N. W. Capron on February 4, 1935. Paratypes 
also ane fara a gall sent by Ed Jacot from Bear Canyon in the 
Huachuca Mountains, Ariz., March 30, 1919, the adults emerging May 
10-28. The writer collected galls at Nogales and Patagonia, Ariz., and 
in the Santa Rita Mountains.
