ENTOMOLOGICAL SECTION. XI 



I obtained specimens of this gall early in January and February, and 

 have succeeded in raising several of the flies. Many of these galls are 

 picked by birds and gnawed by mice ; both of which evidently highly 

 esteem the rich, juicy morsel within. 



Cynips q. batatoides n. sp. 



Galh. — Abrupt, potato-like, irregular swellings of the twigs and 

 branches, varying in size and form, from 0.4 to 0.7 and sometimes an 

 inch long, and 0.3 to half an inch or more broad ; the outer surface is 

 rough of the same color i^s the bark ; internally it is white and in con- 

 sistency not unlike a potato. No kernels; each insect separated by a 

 very thin, hardly perceptible parchment-like substance. In one of the 

 galls I counted fifteen gall-flies. 



Gall-Fly.— 9 .—Length .12 inch. Head brownish-red, finely punctate, slightly 

 pubescent, mandibles bidentate, tips black; palpi yellowish ; antennse 15-jointed, 

 reddish-brown, joint third not quite thrice as long as first and second combined, 

 joints four to eight subequal, nine to fifteen about equal, terminal joint smallest; 

 thorax more coarsely punctate, brownish-red, covered with fine, short, whitish 

 pubescence, parapsidal grooves indistinct, two longitudinal grooves; seutelluni 

 rugoso-punctate, slightly ridged, ridge more perceptible anteriorly and blackish ; 

 wings hyaline, veins black, radial area open, areolet distinct, petiolated ; abdomen 

 smooth and polished, of a uniform reddisli-brown ; legs yellowish or yellowish-red, 

 thighs, coxfe and trochanters darker, feet black. 



Described from numerous bred specimens all females. 



The structural characters of this species indicate the possibility of its 

 belonging to Giraud's genus Dn/cosmus, as defined by Baron Osten 

 Sacken, (loc. cit. 4th article, p. 337). 



The Bud-like Gall of the Live Onk. 

 This gall seems to have been entirely overlooked by all observers ; it is 

 difficult to see why, for although not nearly so plentiful as the previously 

 described species, it is yet by no means rare and quite noticeable upon 

 the ends of the twigs. 



Cyni|>!>i q. >*ucciiii|>es» n. sp. 



G^a//.s-.— Clusters of from five to twenty small galls crowded around 

 a terminal twig or branch; globular, or bud-like in form; externally 

 yellowish-brown with a surface like buckskin, becoming black with 

 age ; internally hard and tough with a single kernel hard and smooth. 

 Diameter from .10 to 0.2 inch. 



Gall-Fly.— (^ .—Itengih .U to .15 inch. Brownish-red; head brown, finely 

 granulated, face densely covered with rather long whitish or yellowish-white 

 pubescence, more sparsely covered on vertex, ocelli black, smooth, shining ; 

 antennfe 1.3-jointed, reddish-brown, pubescent ; third joint thrice as long as second, 

 slightly infuscated, fourth joint nearly as long as third, seventh to twelfth about 

 equal; thorax reddish-brown rather densely pubescent, two black subdorsal vittaj
