BIRCH APHIDS. 513 



96. Bytho8copu8 seniiniidus Say. 



Mrs. Dimmock's note on this insect (Psyche, iv, p. 241) is as follows : 



Bythoscopus seminudus Say (Journ. Acad. Nat. Sci., Phil., 1829 [Mch. Ib31], v. 6, p. 

 307). Fitch (4th Ann. Kept. [N. Y.] State Cat. Nat. Hist., 1851, p. 58) writes, "found 

 on birch trees." 



97. Callaphis betulella Walsh. 



The notes on the following five insects are by Mrs. K. Dimmock 

 (Psyche, iv, p. 240) : 



Callaphis letulella Walsh (Proc. Eutoiii. Soc, Phil., Dec. 1862, v. 1, p. 301,302). 

 Walsh (I. c, p. 302) says this species is abundant in Illinois on Betula nigra. 



98. Callipterus letulwcolens (Fitch). 



Callipterus letulaeoleus Riley and Monell (Bull U. S. Geol. and Geog. Surv. Terr. 

 1879, V. 5, p. 30,31) l^=Aphis betulwcoleus Fitch (4th Ann. Rept. [N. Y.] State Cat. 

 Nat. Hist., 1851, p. 66)], said by Fitch and Monell to feed on birch leaves. 



99. Eriosoma tessellala PMtch. 



Eriosoma tessellata Fitch (4th Ann. Rept. [N. Y.] State Cat. Nat. Hist., 1851, p. 68). 

 According to Glover (Rept. U. S. Commiss. Agric, 1876, p. 39) this species has been 

 found in Maryland upon twigs of Betula. * 



100. Hormaphis papyracece Oestlund. 



Found on the paper birch, corrugating them between the veins, forming long folds. 

 (Oestlund.) 



101. The katydid. 

 Fhaneroptera curvicauda De Geer. 



Phaneroptera curvicauda De Geer (M^m. Hist. Ins., 1773, v. 3, p. 446, pi. 38, fig. 3). 

 This species has been figured, together with the structure of its ovipositor, by Riley 

 (6th Rept. State Eutom. Mo., 1874, p. 164-166), who also gives descriptions of the 

 younger stages and eggs. Miss Murtfeldt (I. c.) describes the mode of oviposition ; the 

 eggs are laid in the margin of leaves — often of oak — between the upper and lower 

 epidermis. Although Riley writes (I. c), " I have had as many as five of these eggs 

 deposited in a single leaf, in one contiguous row, yet they are more often single," yet 

 a single tender leaf of Betula alba, taken at Belmont, Mass., measuring about 8 cen- 

 timeters in length, had the entire margin filled with eggs, presumably of this spe- 

 cies. Only two or three leaves were found thus attacked, and the one of which the 

 size is given above contained 102 eggs. (Mrs. Dimmock.) 



102. The red-legged locust. 

 Caloptenua femur-rubrum De Geer. 



Caloptenus femur-rubrum De Geer (M6m. Hist. Ins. 1773, v. 3, p. 498, pi. 42, fig. 5) 

 often strips the leaves from low bushes of Betula alba about Cambridge, Mass. (Mrs. 

 Dimmock.)
