ENTOMOLOGICAL SECTION. XUl 



Now, the largest specimen I have ever found of the present gall, and 

 I have collected hundreds, is never more than three-quarters of an inch 

 in diameter, and instead of the leaves being oval, they are strictly 

 lanceolate ; the cells or kernels too, instead of being smooth, are pitted, 

 somewhat like a peach stone. They likewise never drop to the ground, 

 but remain cemented to their cup, and the fly escapes by pei'forating 

 a hole in the top. I have found hundreds of the black dry galls 

 containing cells so perforated, and have never seen more than one cell 

 to a gall. 



Cynips q. foliata n. sp. 



Galls. — In outline urn-shaped, composed externally of numerous, 

 lanceolate, leafy-like spines, developed from the axillary leaf bud ; dia- 

 meter one-half to three-quarters of an inch ; internally consisting of a 

 greyi.sh acorn-lfke cup, with a single kernel imbeded half way ; cup 

 .20 inch in diameter. Kernel brownish .15 to .18 inch long by .07 to 

 .10 wide, somewhat pointed at top and slightly contracted in the middle? 

 iiTcgularly pitted and grooved, somewhat like a peach stone only the 

 grooves arc not so deep. 



Gall-Fly.— $> . — Length .12 of an inch. Head brown, face to mandibles covered 

 with rather short, thick, white pubescence, a series of grooves or acieuUitions 

 converging towards mandibles, the latter black vertex rugoso-punctate, free from 

 pubescence, palpi yellowish, terminal joint slightly infuscated at tip ; antennre 

 1.3-jointed, brownish-red, third joint twice as long as second, others to tenth sub- 

 equal, tenth, eleventh and twelfth very short, about equal, thirteenth not quite 

 twice as long as twelfth ; mesothorax and seutellum reddish-brown, rugoso-punc- 

 tate, covered with short whitish pubescence, parapsidal grooves distinct, brownish, 

 two short subdorsal grooves starting from collare and extending backwards not 

 quite to middle of thorax ; abdomen smooth, bright, shining reddish-brown ; legs 

 yellowish-red, feet and coxse brownish or blackish; wings hyaline, veins yellow-

The Live Oak Woolij Gall. 

 This unique and beautiful little species approaches nearest to the one 

 described by Dr. Fitch, (see Ann. Report N. Y. State Agi-i. Soc. Fifth 

 Report, p. 814), under the name of C. q. lana, readily distinguished from 

 it, however, by size, coloration and in having but 14-jointed antennae. 



Cynips q. lanigera n. sp. 



Gall. — Small, flattened, circular or in-egular tufts of rather long 

 whitish or ferruginous wool, on the under parts of the leaf; attached 

 generally to the principal vein and covering from two to six small, 

 irregvilar, smooth brownish seed-like kernels, .06 to .08 inch in diameter. 

 Diameter of wooly covering .02 to .03 inch.
