Kinsey: Studies of Cynipidse 



99 



TYPES. — 1 female, 7 galls. Holotype female, paratype galls iii 

 The American Museum of Natural History; paratype galls at Stanford 

 University, the U.S. National Museum, and with the author. Labelled 

 San Bernardino, California; January 31, 1920; Kinsey collector. 



Adults had all emerged before January 31, tho the galls 

 still possessed a bloom, probably indicating that the insects 

 had emerged not long previously. 



This variety again illustrates the remarkably distinct 

 nature of the fauna of the San Bernardinos. There is not 

 the least difficulty in separating this variety from either of 

 the others, but if one will compare the descriptions of the 

 adults word for word he will be struck by the fact that part 

 of the characters of this variety match those of variety 

 sanctx-clarse, and part those of fuscior. On a whole the vari- 

 ety comes nearer fuscior. 



Neuroterus cupulae, new species 



FEMALE. — Almost wholly black, a light ring at base of the third 

 segment of the antennae; niescpleur^ finely coriaceous; areolet large; 

 length up to 1.7 mm. HEAD: As wide as the thorax, moderately 

 widened behind the eyes; black, mouthparts deep rufous brown; very 

 finely and evenly shagreened, smoother on the face, face scatteringly 

 punctate and pubescent. Antennae short, black, piceous black basally, 

 apex of the second segment and base of the third usually yellow piceous; 

 with 13 segments, the last segment hardly longer than the preceding. 

 THORAX: Entirely black; mesonotum practically smooth, shining, and 

 naked, very faintly and microscopically shagreened; entirely without 

 grooves; scutellum large, oval, smooth, and shining, very faintly and 

 microscopically shagreened, an arcuate furrow at the base; pronotum 

 very finely, irregularly puncto-shagreened at the sides; mesopleurse 

 shagreened-coriaceous. ABDOMEN: Piceous black; entirely smooth 

 and shining, and practically naked; large, irregularly triangular, pro- 

 truding ventrally as far as or further than dorsally ; the second seg- 

 ment occupying about half the area; ventral valves at a 60° angle to 

 almost vertical. LEGS: Piceous black, brownish yellow on the joints 

 and on the tarsi, the tips of the tarsi dark; finely pubescent; tarsal 

 claws simple. WINGS: Clear, set with fine hairs, anterior margins 

 scarcely ciliate ; veins rich brown ; areclet large to very large ; cubitus 

 reaches the basalis below the mid-point, distinct for the whole length; 

 radial cell open, second abscissa of the radius somewhat curved, most 

 so toward the tip, not quite reaching the margin of the wing; first 

 abscissa sharply angulate. LENGTH: 1.0-1.7 mm. 



GALL. — Only a larval cell buried in the wood of the acorn cup. The 

 cell oval, averaging 1.5 mm. wide by 2.2 mm. long; the walls hard but 

 not thick; entirely hollow. Buried wholly or in part in the wood of the 

 acorn cup, oftenest at the base; part of the cell sometimes visible within
