 1891. Butler, Entomologist, xxiv, 2Q2,^lambda. 



Habitat. — Canada; Maine; RFasKsachusetts ; New York. 



The type is in the British Mnseuui. There is very good authority 

 for making this a synonym or at least a variety of lambda; but I do 

 not feel ready to admit the identity without a more critical study than 

 has yet been made.

Habitat. — Canada; Northern, Eastern, and Middle States; Wash-

The type of the species is in the British Museum; that of the variety 

 is with Mr. ISTeumoegen.

 1873. Grt., Bull. Buff. Soc Nat. Sci., i, 145, Anytus. 

 1878. Grt., Bull. Geol. Surv., iv, 180, Lithophane. 



Habitat. — Canada; Northern, Eastern and Middle States; Colo- 

 rado. 



A specimen marked type, by Mr. Grote, is in the British Museum. 

 The species is certainly not a Xylina, but seems to be congeneric with 

 Folia acuHssima. As the latter is not a Polia, nothing would be gained 

 iu accuracy by getting capax into that genus at present. 



X. carbonaria Harv.* 



1876. Haw., Can. Eut., viir, 55, Lithophane. 



Habitat. — Oregon; California; Colorado. 



The type is in the Hy. Edwards collection. This also must be re- 

 moved from Xylina^ the species affording a quite remarkable structural 

 character.
