Kyes red, ocellar spots reddish. Antennae and legs dusky. Sur- 

 face of the whole body densely granulated. 



Migratory female. — I^ength of body 0.9-1.2'""-. Expanse 

 of wings 2.2-2.8™™- Color orange, the prothorax somewhat the 

 darkest. Head, mesothorax, scutellum and sternal plate, black. 

 Antennae and legs dusky ; eyes brown or dark purple. The pro- 

 thorax is often faintly dusky and is often marked medio-dorsally 

 with three more or less distinct, minute spots, of which the two 

 smaller, anterior ones, are more or less oval, and the larger pos- 

 terior one linear. Antennae about as long as the tibiae : joints 

 I and 2 about equal in length and but faintly annulated ; joint 

 3 much the largest and almost three times the length of the other 

 two combined, almost uniform in diameter throughout its whole 

 length, quite straight, with a short pedicel at base and terminat- 

 ing in a distinct nipple which shows at least two well-marked 

 annulations and is provided with three extremely fine hairs ; the 

 whole joint is but faintly annulate, the annulations more numer- 

 ous and more distinct at its basal fourth, the ' sensoria sub- 

 obsolete, particularly the basal one, the terminal one very slender 

 and about one-half as long as the joint. Wings ample, faintly 

 dusky, the veins and stigma darker, the subcosta yellowish at 

 base; of the veins the discoidal vein is darkest, and all are bor- 

 dered with a faint dusky shade. The discoidal vein arises some- 

 what nearer to the stigma than to the base of the wing and 

 branches near its middle ; the stigmal vein is but slightly curved 

 and starts from about the middle of the stigma. I^egs rather 

 short. 



Phylloxera symmetrica n. sp., Pergande. 



This species, as far as its gall is concerned, appears to be 

 closely related to, if not identical with. Ph. conifera Shinier 

 (Trans. Am. Ent. Soc, V.ol, II., 1868, p. 397), but as his descrip- 

 tion, both of the gall and its architect, is rather vague, brief and 

 general in characterization, so much so as to apply equally as 

 well to many others, it is deemed more expedient to describe it 

 as new. 



This gall has been noticed on young trees of Hicoria (Catya) 

 tomentosa and some other species, in the neighborhood of Wash-
