incomplete, reaching but half-way to anterior margin, median longi- 

 tudinal lines extending half-way to posterior margin, smooth lines over 

 base of wings distinct, pleura finely striated, with a triangular smooth 

 area posteriorly, scutellum rugose, sparsely pubescent, basal foveas 

 large, elliptic, oblique, with smooth bottom, not approximate, metano- 

 tal ridges only slightly curved, faced with black. Abdomen about as 

 long as head and thorax together, smooth and shining, more or less 

 lenticular in shape, second segment occupying half its length, 3rd 

 segment rather broad, following segments narrow, ovipositor sheath 

 exserted, concolorous. Wings rather opaque whitish, faintly iridescent, 

 veins faint, yellowish, radial cell narrow, open at the margin, vein at 

 base arcuate, almost angulate, areolet indistinct, cubitus not reaching 

 basal vein. Length 2 mm. 



Gall. Very small, flat, reddish, disc-shaped galls on the under side 

 of leaves of Quercus lobata, about 3 mm. in diameter, slightly elevated in 

 the center. Much smaller than gall of Andricus pallersonce and quite 

 distinct from it. 



Andricus wisliceni Ashm. 

 Andricus wisliceni, Ashmead, Proc. U. S. Nat. Mus., vol. 19 (1896), p. 119. 



"Gall. A small, globular gall, with a slight projection at base 

 where it is attached to the twig ; it varies in color from a yellow brown to 

 dark brown, and some are mottled with purple and brown. It is hard, 

 and contains in the center a small larval cell; diameter, 3-4 mm. 



"Gall-fly. Female. Length, 3 to 3.4 mm. Pale brownish yellow, 

 almost devoid of pubescence, the abdomen polished and discolored witn 

 brown, eyes dark brown, the mandibles black. Head and thorax finely 

 punctate, shining; in front of the anterior ocellus is a deep transverse 

 foveas, and there are some coarse scattered punctures on the mesonotum. 

 Antenna' 14-jointed, the 3rd joint about one-eighth longer than the 4th, 

 the joints from 7th to apex short, about twice as long as wide, dusky, 

 and delicately fluted. Parapsidal grooves distinct, the groove on the 

 shoulders very long, distinct, and a little bent anteriorly. Scutellum 

 cushion-shaped, rugose, the foveas at base large and distinct, separated 

 only by a slight carina; pleura smooth, but under a high power showing 

 faint delicate strias. Wings hyaline, the pubescence short, veins, 

 except the sub-marginal vein from the portion extending from the 

 basal vein to apex, and the angulated cross vein at base of marginal cell, 

 which arc brownish or piceous, yellowish.

"Nine female specimens, reared October 14, 1SS6, from the galls
