OF WASHINGTON. 215 



Tinea acapnopennella Clemens. 



One type, Clemens' No. 213 ; alar exp., 14 mm. 



Specimens, determined by Lord Walsingham and agreeing with 

 this type, are in the U. S. National Museum. 



Homosetia tricingulatella Clemens. 



One type, wings on left side lacking, Clemens' No. 198 ; alar 

 exp., 1 1 mm. 



This is the same species as described by Chambers subsequently 

 as Pitys miscecristatella. Chambers called attention to the simi 

 larity of both his genus and species to Clemens' form, but very 

 excusably separated his genus, judging as he did only from Clem 

 ens' description, which omits any mention of the characteristic 

 tufts of raised scales, though they are found in the types. I am 

 unable to find any justification for the genus Semele Chambers,* 

 which Chambers later confessed! was probably not well separated 

 from Pitys. I have examined the type of Semele cristatella 

 Chambers, which is the type of the genus. It agrees in every 

 respect generically with Pitys. Both of these genera fall before 

 Clemens' earlier Homosetia. Specimens collected at Washing 

 ton, D. C., and in Kentucky, are in the U. S. National Museum. 



Homosetia costisignella Clemens. 



One type without wings on left side, Clemens' No. 199; alar 

 exp., ii mm. 



This is without doubt the same as Pitys fasciella Chambers. 

 Specimens compared with Clemens' type are in the U. S. National 

 Museum. 



Chauliodus (?) canicinctella Clemens. 



One type consisting only of thorax and right fore wing, Clem 

 ens' No. 214; alar exp., 10 mm. 



In spite of its poor condition, the type will ultimately enable 

 identification, as the coloration of the fore wing is quite striking, 

 and well described by Clemens. I have at present no specimen 

 like it. and cannot give any definite opinion on its generic posi 

 tion. If Clemens' generic description is correct, as is probably 

 the case, the species cannot be included in Epermenia Hiibner 

 ( Chauliodus Treitsche). 



Ornix boreasella Clemens. 



One type, head, abdomen, and right wings missing, Clemens' 

 No. 217 ; alar exp., 9 mm. 



I have no specimen like this. The species must be retained 

 provisionally in the genus Ornix, though Clemens' description 

 and what is left of his type, indicate that it cannot belong there.
