78 LORD WALSINGHAM ON NEW TINEIDyE. [Feb. 17, 



biviella (Verb. z.-b. Ges. Wien, xxiii. [1873], p. 226, pi. iii. fig. 10), 

 where it is accurately figured. 



The second {A. bellela) is closely allied to the European Adela 

 deyeerella (Linn.), differing only in the richer colouring and in the 

 darker purple hind wings. The longitudinal stripes before and 

 beyond the central band, as well as the margins of the band itself, are 

 very distinct, and of a brilliant shot purplish-blue, whereas these 

 and the central band itself are paler in the European species. The 

 wings are perhaps slightly shorter in proportion to their length than 

 in A. degeerella. 



The third {Adela albicornis), which is very distinct from any other 

 known Adela, was first described by Mr. Stainton as Adela nata- 

 lensis (Trans. Ent. Soc. Lond. n. s. vol. v. p. 222), the specimens 

 in the British Museum described by Walker being from Mr. Guen- 

 zius's collection, which also supplied some of those described by Mr. 

 Stainton. 



Dr. Brackenridge Clemens, Proc. Ent. Soc. Phil. 1864, vol. ii. 

 p. 426, describes Adela ridinysella from Virginia. 



Prof. Zeller, in the ' Verhandluugen der zoologisch-botanischen 

 Gesellschaft in Wien,' vol. xxiii. (1873), describes A. biviella 

 (p. 226, pi. iii. fig. 10) from Massachusetts, above referred to, Adela 

 chalybeis (p. 225) from Texas, a species with which I am not 

 acquainted, and Adela schlcegeri (I. c. p. 227, pi- iii. fig- H) from 

 Ohio, of which the figure faithfully represents the species under 

 the name of A. ridingsella in the collection of the Entomological 

 Society of Philadelphia ; and in vol. xxv. p. 342, pi. x. fig. 50, of 

 the same publication he further describes and figures Adela trigrapha 

 from California. 



Mr. Chambers, in the' Canadian Entomologist,' vol. v. p. 73, 1873, 

 describes Adela bella and Dicte coruscifasciella, both from Ken- 

 tucky. In (Can. Ent.) vol. viii. pp. 103, 104, he describes Adela 

 {Nemotoisi) trifasciella, Adela fasciella (which he suggests may be 

 the female of the preceding species), and Adela "Jlammeusella," all 

 from California. 



In (Can. Ent.) vol. ix. pp. 206, 207, he refers to A. biviella, Zell., 

 and describes the female of this species (which has a "straw-yellow 

 head") from Maine; he also amends his previous description of A. 

 bella, and points out that his " Dicte (Adela) coruscifasciella^' is 

 the same species as Adela schlcegeri, Zell., which it precedes. 



The same author, in the ' Bulletin of the United-States Geological 

 Survey,' 1878, vol. iv. no. 1, pp. 127, 128, in his "Index to the 

 described Tineina of the United States and Canada " (in which he 

 omits to notice any of the species described by Mr. Walker), gives 

 a list of the known species of Adela from those countries. In this 

 list he sinks his A. fasciella as a synonym of A. trigrapha, Zell., but 

 retains as a distinct species his A. trifasciella, which he had 

 previously suggested might possibly be the ma[e oi A. fasciella, and 

 alters the spelling oi A. jlammeusella to A. fumensella. 



After careful comparison of descriptions, of figures, and of type 

 specimens where such has been possible, I would suggest tlie
