ican literature, together with brief notes on the economic importance, 

 if any, and the first record of its occurrence in Ilhnois. An asterisk (*) 

 before the species indicates that it is here recorded from Ilhnois for 

 the first time, those having Illinois as the type locality are referred to 

 hy a " t" before the name, and those doubtfully occurring in Illinois, 

 having only been reported by Hunter's compiled list.^, so far as I 

 have been able to find, are noted hy a " d" before the name. 



^Tychea brevicornis Hart: 18th Rept. St. Ent. 111. (1894), p. 97, 

 1 fig. Not uncommon in Central Illinois on the roots of grass. Euphor- 

 bia, and corn, but of very little economic importance. First reported 

 by Forbes. 



^ Tram.a erigeronensis Thos.: Hart, loc. cit., p. 93, 1 fig. Common 

 at Urbana, 111., on dandehon roots, invariably attended by the ant, 

 Lasius flavus. Also common on roots of Erigeron canadense and corn. 

 First reported by Thomas. 



^ Forda occidentalis Hart: loc. cit. p. 95, 1 fig. Common on grass 

 and corn roots and occasionally injurious. First reported by Forbes. 



^ Rhizobius eleusinis Thos.: List of Aphid. U. S., Bull. 2, 111. St. 

 Lab. Nat. Hist. (1878), p. 15. I have never taken this species, which 

 Thomas described from specimens collected on roots of Eleusine 

 indica at Carbondale, 111. 



'^ R. lactucce Fitch: 14th Rept. Ins. N. Y. (1872), p. 360. Thomas 

 quotes Fitch, and there is no mention of its occurrence in Illinois. 



' R. voce Thos.: 8th Rept. St. Ent. 111. (1879), p. 166. Mr. C. A. 

 Hart considers this as probably a Dactylopius. First reported by 

 Thomas, which is the only record of its collection, so far as I am able 

 to learn. 



* R. spicatus Hart: 18th Rept. St. Ent. 111. (1894), p. 104, 1 fig. 

 A rare species occurring on roots of grass, Panicum, and corn. First 

 reported by Forbes. 



Phylloxera carycecaulis Fitch: Pergande, N. A. Phylloxerinse, Vol. 

 9, Davenport Acad. Sci. (1904), p. 244, 2 figs. This is the commonest 

 species of Phylloxera attacking hickory in Illinois, but like the other 

 species of this genus it rarely becomes sufficiently abundant to require 

 artificial means of control. First reported by Shimer. 



P. caryce-fallax Riley: Pergande, loc. cit. p. 214, 6 figs. First re- 

 ported by Pergande. 



P. carycefolice Fitch: Pergande, loc. cit. p. 194, 2 figs. I have 

 taken this hickory gall-maker on several occasions in Northern Illinois. 

 My collection of winged females have been made throughout the 

 month of June. First reported by Pergande.
