American Insect Galls: Thompson S7 



243. Cecidomyia. Flask gall. Carya. Mas.s. July. 3 mm. long on leaf, flask-shaped, pros- 



trate, white or pink. Fairly constant recurvation, plate 12, 243. 

 Possibly Caryomyia aanguinolenla 0. S. 



244. Cecidom3da. Canja. Mass. July. On leaf; crimson-green, smooth and small depression 



above; globular with slight point at apex below. Dark crimson, shining and sticky 

 to touch. 4 mm. diameter. Single, small, white larva, plate 12, 244. 

 Caryomyia caryce O. S. 



245. Cecidomyia. Carya. Mass. July. Sub-globular, surface at all stages with minute 



rugosities, glutinous, yellow. Wall 1-3 diameter, leathery, larva white, plate 11, 

 245. 



Caryomyia caryce O. S. 



251. Nectria ditissima. Carya. Hickory. "Large, warty, cancrous growth." Nectria ditis- 



sima. 

 253. Phylloxera caryae-septum. Packard '90, p. 322. Carya. Mass. July. Above leaf 



attenuate, conical, 4-5 mm. spht at apex to filaments with an orifice; below similar 



but thinner. 



254-5. Hormomyia caryse. 0. S. cf 9 . Carya. Mass. July. When young much like 

 Diplosis caryce; when old, a larger gall with thinner walls, very brittle. Yellow. 

 Gall resembles a globular onion in translucency and color. Very small. It also 

 resembles a young tubicola, but as it grows it swells out almost to shape of Diplosis 

 carya;, attached, however, by broader base and is more elevated. Very variable 

 gall, plate 12, 254, 255. 

 Caryomyia caryoe O. S. 



256. Pseudo-holotricha. Carya. Mass. July. Cavity more basal and less hairy, subglobular, 



sessile, but may be holotricha No. 114. 

 Possibly Caryomyia holotricha O. S. 



257. Cecidomyia. Carya. Mass. July. Conical, sessile or subsessile at all stages, wall thick, 



not translucent, slightly pubescent. Numerous on under side of leaves. Strongly 

 elevated above leaf, 1-2 mm. Less tapering than C. sanguinolenta, No. 241, plate 

 12, 257. 



Caryomyia (?) caryce O. S. 



258. Cecidomyia. Double-decker. Carya. Mass. July. Hard, rounded, slightly elevated 



spot above leaf. As gall grows the blister area is lifted up as a roof, plate 13, 258. 



Caryomyia inanis Felt probably true producer; Parallelodi ptosis carya; Ve\{, presumably an 

 inquiline. 



259. Cecidomyia. Carya. Mass. July. Resembles "pseudo-diplosis No. 255" at all stages, 



but is finely pubescent. Wall thin and brittle, i)late 12, 259. 

 (?) Mycodiplosis hololricha Felt. 



260. Eriophyes. Margin-rolled gall. Carya. Mass. July. Margins of loaf rolled toward 



upper face and much crinkled. Mites live within the fold, plate 10, 260. 

 274. Cecidomyia. Carya. Mass. July. Small attachment on upper side of leaf 2 mm. tall. 



Conical, jug-shaped with apical pubescence and cap. 

 301. Phylloxera caryae-semen. Packard '90, p. 322. Carya. Mass. Sept. 2-3 mm. broad 



on upper side of leaf; elevation generally globular but quite irregular as to height; 



central pit usually present, wall opaque; slightly conical with short nipple on lower 



side breaking into a variable number of pubescent points, plate 13, 301. 

 308. Cecidomyia cynipsea. O. S. '67, p. 193. Carya. Subglobular, woody swelling, surface 



rough with jioints below. Polythalamous, cells vortical, oblong. 

 328. Phylloxera. Carya. Juno. Galls small up to 8 mm. Semi-globular to quite globular, 



flat beneath. Orifice more or less transverse, fleshy lips. Wall rather thin but not 



papery; color pale yellow. Migrant is close to 130.
