MISCELLANEOUS PUBLICATIONS OF THE ENTOMOLOGIST. 



The following list comprises publications during the years 1882 and 

 18S3, mainly in agricultural journals, most of which were in reply to in- 

 quiries made in relation to insects of economic importance: 



Insects on Sweet Potato Vines. (Country Gentleman, for Feb. 23, 

 1882, xlvii, p. 149, c. 2-3 — 12 cm.) 



The larvK infesting sweet potato vines in St. Louis, Mo., are proba- 

 bly those of Coptocycla aurichalchca. Remarks upon the species and 

 means of destruction, viz., application of Paris green and London pur- 

 ple. 



Entomological — The Anatomy of the Mouth Parts and the Sucking 

 Apparatus of some Diptera. (Country Gentleman, for February 23, 

 1882, xlvii, p. 151, c. 2-3 — 13 cm.) 



The paper was prepared by Mr. George Dimmock, of Cambridge, 

 Mass., as a dissertation for obtaining the philosophical doctorate at 

 Leipsig University. In it the mouth-parts of Culex, Boinbylhis, Eristalis, 

 and Miisca are ably treated, of, and fully illustrated in four excellent 

 plates. A resume ot previous publications on the subject is given. 



Millions of Grasshoppers in Midwinter. (Albany Evening Journal, for 

 February 25, 1882.) 



Grasshoppers observed upon the surface of snow in Westchester 

 county, New York, prove to be Ty-agocephala viridifasciaia^ "the green- 

 striped locust " of Dr. Harris. This species has on different occasions 

 appeared during warm days in winter, but has never been recorded as 

 very injurious. Their early appearance at this time will cause the 

 death of large numbers, and lessen the brood of the summer months. 



A Winter Grasshopper — Tragocephala viridifasciata. (Country Gen- 

 tleman, for March 9, 1882, xlvii, p. 189, c. 2 — 16 cm.) 



Identification of the species, occurring in Genesee county, N. Y., in 

 February — its history — is not often injurious — will probably be killed 

 by frosts before its food appears. 



The Hickory-Borer — Cyllene pictus {^Drury). (Country Gentleman, 

 for March 9, 1882, xlvii, p. 189, c. 2-3 — 8 cm.) 

 The species was for a long time confounded with the locust-borer, C.
