AMERICAN LEPIDOPTERA. 197 



Genus STILBOSIS. 



372, 1020, &c. Stilbosis tesquella. 



Stilbosis tesquella, Clem. Proc. Ac. Nut. Sci. Phila. 1860, ]». 170; Tin. Nor. Am. 

 pp. 40, 129. 



Stilbosis tesquella, Cham. " Index." 



Laverna? quinquecristatella, Cham. Cin. Soc. Nat. Hist. 1881, p. 5. 



Mr. Chambers's type of Laverna quinquecristatella in Mr. Groodell's 

 collection proves that this name must give place to that which accom- 

 panies Dr. Clemens's prior description of the same species. 



I think I can detect very short maxillary palpi not mentioned by Dr. 

 Clemens. 



Walshia amorphella, Clem., as noticed below, has also been placed by 

 Mr. Chambers in the genus Lavema, to which it undoubtedly has the 

 appearance of being allied. 



Genus WALSHIA. 

 977. Walshia stmorphella, Clem. Proc. Enfc. Soc. Phil. ii. p. 419. 

 Laverna miscecolorella, Cham. Can. Ent. vii. p. 51. 



This type of L. miscerahrelln, received from Mr. Chambers, and pre- 

 served in the collection of the Peabody Academy of Sciences at Salem, 

 agrees with my examples of Walshia compared with Clemens's type at 

 Philadelphia in 1872. 



Genus S< If It IX K ENS I I ! XI I. 

 827,828. Sckreckensteiiiia festaliclla. Hub. (Woeke, Cat. 2705). 



This generic name adopted in Wocke's Catalogue should probably take 

 precedence of Chryscorys, under which name, following Dr. Jordan and 

 Mr. Stainton, I referred this species to the Pterophoridae (Pter. Cal. & 

 Or pp. 1,2). Its larval habits, especially in the formation of an open 

 network cocoon before pupation, give rise to considerable doubt whether 

 it can rightly be included in that family. 



Mr. Chambers places his beautiful Lithariapteryx abroniseella 

 among the Grlyphipterygidae, but it agrees in neuration and iu the form 

 of the wings almost exactly with Schreckensteinia. Their oral parts are 

 also very nearly similar. In having no maxillary palpi it would appear 

 to approach the subfamily of Elachistina rather than the (xlyphiptery- 

 gina. 



Genus COSJIOPTERYX. 

 228, 229. Cosiii©i>l«»rj x l°ernal<lella, sp. now 



There are two specimens of a new species of Cosmopteryx in Prof. 

 Fernald's collection, for which I propose the above name. This is a most 

 interesting species, very closely allied to the European Cosmopteryx 

 HenigieUa, Zell. (AVocke. Cat. _!70!> . differing from it in the following 

 particulars. The upper median streak before the first fascia is short and
