BIRCH APHIDS. 513 



96. Bythoaeopus seminudua Say. 

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



Bythoscopus seminiidus 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): 



CallapMs letulella Walsh (Proc. Entom. 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 hetulcecoUns (Fitch). 



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

 1879, V. 5, p. 30,31) {_'iz=Aphis betukecoleus 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 Fitch. 



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 papyracew Oestluud. 



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

 (Oestlund.) 



101. The katydid. 

 Phaneroptera curvicauda De Geer. 



Phaneroptera curvicauda De Geer (M6m. 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 Entom. 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 o^ 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-ruhrum De Geer. 



Caloptenus femur-rubruyyi 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.)
