XXV. 



Chambers .shortly afterwards gave up this g-enus and inehulcd his 

 species in Gelechla as ^ synon^'ni of Clemens's Gdeclua longifasclrJId., 

 but a name is needed to signify the genus, which Chambers can hardly 

 be said to have defined, but which has the following characters in com- 

 mon with cKrvlstrlgelld. Chambers' name must stand in preference to 

 Mey rick's later name Xenolcchia. 



I strongly suspect that Chambers' genus, AclrasteUt^ is synonymous 

 with the present genus, in which case that name would supplant 

 Teljjhum., but for the time being it must be left as "unrecognized." 

 The types of the two species, Adrastela alexandriaeella and ^l. faHcl- 

 eUa^ on which Chambers erected the genus, are lost, and though I feel 

 rather certain that 1 have recognized both species as belonging to Tel- 

 phiim, still altogether insufficient collecting has been done in Kentucky, 

 from where these species are described, to warrant final conclusions 

 from the limited material on hand, and at present I must leave both 

 genus and species as unrecognized. There is no Avay to include the 

 genus in any talile, as Chambers did little more than attach the name 

 to those two species without further specification; the only tangi])le 

 generic character given is the tufted forewings. 



Telphma has the following characters: Second joint of labial palpi 

 thickened with rough scales beneath, terminal joint slender pointed. 



Forewings elongate pointed, 12 veins, 7 and 8 stalked, 6 separate or 

 out of 7 near base; hindwings trapezoidal, apex pointed termen sinu- 

 ate, as broad or broader than the forewings; 8 veins, 6 and 7 stalked, 3 

 and 4 separate, 5 nearest 4. Forewings often w4th tufts of raised scales. 



The American species at present recognized as belonging to this 

 genus may be separated by the following table:
