ous species. Here it niigiit be added 

 tliat Betula alba is very useful in 

 rearing certain polypliagous species, 

 since its leaves remain in good condi- 

 tion for a long time, and are the favor- 

 ite food-plant of many insects. Certain 

 polyphagous species, as Attacus cecro- 

 pia, do not feed readily on other food- 

 plants after having eaten birch. Larvae 

 (especially of geometi-idae) of which 

 the food-plant is unknown, can often be 

 reared successfully on Betula' alba, a 

 fact to which I owe my successful rear- 

 ing of E)idrofia armataria. 



Orthoptera. 



Phaneroptera curvicauda De Geer (Mem. 

 hist, ins., 1773, V. 3. p. 446, pi. 3S, 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 (/. c. ) describes 

 the mode of oviposition : the eggs are laid in 

 the margin of leaves — often of oak — between 

 the upper and lower epidermis. Altho 

 Riley writes (/. 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 \t^i of Be- 

 tula alba, taken at Belmont, Mass., measur- 

 ing about 8 cm. in length, had the entire 

 margin filled with eggs, presumably of this 

 species. Only two or three leaves were 

 found tlius attacked, and the one of which 

 the size is given above contained 102 eggs. 



Caloptentis femui—rubrum De Geer (Mem. 

 hist, ins., 1773, v. 3, p. 498, pi. 42, fig. 5) 

 often strips the leaves from low bushes of 

 Betula alba about Cambridge, Mass. 



Rhynchota. 

 Eiiosoma tessellala Fitch (4111 ann. rept. 

 [N. Y.] state cab. nat. hist., 1S51, p. 68). 

 According to Glover (Rept. U. S. commiss. 



agric, 1876, p. 39) this species has been 

 found in Maryland upon twigs of Betula. 



Calliftcrus bctulaecoleiis Riley and Monell 

 (Bull. U. S. geol. and geog. surv. terr., 1879, 

 V. 5, p. 30-31) [.' ^^ Aphis bctulaecoleiis Fitch 

 (4th ann. rept. [N. Y.] state cab. nat. hist., 

 1S51, p. 66)]. Said by Fitch and Monell to 

 feed on birch leaves. 



Calaphis betulella Walsh (Proc. Entom. 

 soc. Phil., Dec. 1862, v. i, p. 301-302). 

 Walsh (/. c, p. 302) says this species is 

 abundant in Illinois on Betula nigra. 



Atkysatius variabilis Fitch (4th ann. rept. 

 [N. v.] state cab. nat. hist., 1851, p. 60) is 

 stated by Fitch (A c.) to be "abundant on 

 birch trees, in June," and the same author 

 states (Ann. rept. N. Y. state agric. soc, 

 1858, V. tS, p. 853) that this species punctures 

 leaves and succulent shoots of birch. A 

 brief description of this insect is given by 

 Packard (Bull. 7, U. S. entom. comm., 

 1881, p. 128). 



Atkysanus abietis Fitch (4th ann. rept. 

 [N. Y.] state cab. nat. hist., 1851, p. 60) is 

 stated by Fitch (Ann. rept. N. Y. state 

 agric. soc, 1857, v. 17, p. 749) to feed on 

 birch. Packard (Bull. 7, U. S. entom. 

 comm., iSSi, p. 235) briefly describes tliL 

 species and gives Betula as food-plant. 



Atkysanus minor Fitch (4th ann. rept. [N. 

 Y.] state cab. nat. hist., 1851, p. 60). Fitch 

 (/. c.) writes "Common on birch trees," and 

 adds (Ann. rept. N. Y. state .agric soc, 1S5S, 

 V. 18, p. 853) that it punctures birch leaves. 

 Packard (Bull. 7, U. S. entom. comm., 18S1, 

 p. 128) briefly describes this species. 



Atkysanus feiiestratus Fitch (4th ann. rept. 

 [N. Y.] state cab. nat. hist., iSji, p. 60) is 

 stated by Fitch (/. c.) to be found "on birch 

 trees," and (Ann. rept. N. Y. state agric soc. 

 185S, V. iS, p. 853) to puncture birch leaves. 

 This species is briefly described by Packard 

 (Bull. 7, U. S. entom. comm., iSSi, p. 128). 



Tkelia univittata Harris (Treatise on ins. 

 injur, veg. , 1842, p. iSo). One specimen 

 taken sucking juices of a twig of Betula alba. 

 June 1884. This species is found on oak. ac-
