It will be seen tliat Hiibner, as early as 1816, detected the error of 

 Abbot and Smitb iu regarding our species as identical with the Euro- 

 pean C. neustria^ the name proposed by him should thus be retained, 

 having priority over subsequent descriptions. Fabricius' B. americana 

 being now entirely unknown, I propose that Dr, Harris' name be re- 

 tained for the second N. Am. species of the genus — Clisiocampa ame- 

 ricana, Harris. 



ADELOCEPHALA, Boisduval. 

 Adelocephala bicolor. 



Dryocampa bicolor, Harr., Rt. Ins. Mas3. (1841). 

 " 3rd Ed. p. 401. (1862). 

 Walsh, Proc. Bost. Soc. Nat. Hist. p. 293. (1864). 

 Sphingicain-pa distigma, Wal«h, Proc. Bost. Soc. Nat. Hist, p 290. (1864). 

 Anisota bicolor, Grote, Proc. Ent. Soc. Phil. p. 93. (1864). 



From Anisota the present species differs by the pectinations of the 

 2 antenna3, among other sufficiently distinctive generic characters. 

 After having seen Mr. Walsh's material I am of opinion that the spe- 

 cimens he describes as Dryocampa bicolor and Spliingicampa distigma 

 belong to one and the same species. I am indebted to the kind offices 

 of F. Gr. Sanborn, Esq., for the information that no specimens of this 

 species remain in Dr. Harris' collection at the present day, but have 

 no doubt that the identification of Dr. Harris' description by Mr. Walsh, 

 and with which specimens in the Coll. Ent. Soc. Phil, correspond, is 

 the correct one. We are indebted to Mr. Walsh for the discovery and 

 lucid description of the larva of this interesting and fine species, differ- 

 ing remarkably structurally from the larvae of the nearly allied species 

 of Anisota. Judging from the figures of Dr. Herrich-Schfeffer, our spe- 

 cies is generically identical with the South American forms which 

 are figured in Lep. Exot. fig. 77-78, 306-307, and perhaps fig. 304-305, 

 and for which Adelocephala Boisd. is retained. Should, on an ex- 

 amination of actual specimens, our species be found generically dis- 

 tinct, the name proposed by Mr. Walsh will prevail, and our species be 

 known as Sphingicampa bicolor. 



Notodonta basistriens, "Walker. 



I am informed by Mr. Walker that my identification of this species 

 on page 93, PI. 1, fig. 1,S huj. scrip. (1864), is correct, corresponding 

 with the typical specimen in the British Museum Collection.
