U)8 m^LLETIN 41, UTSTITED STATES NATIONAL MUSEUM. 



llABTTAT. — United States east of the Rocky Moimtains; Colorado; 

 Jh'itish Coliind)ia, July to October, 



Typical specimens are in the British Museum. I have not seen the 

 type of Mr. Grote's variety; that described by Prof. Eiley is in the 

 National Museum. 



Genus ANORTHODES Smitli. 

 1891. Smith, Trans. Am. Ent. Soc, xvili, 114. 



A. prima Smith.* 



1891. Smith, Trans. Am. Ent. Soc, xviir, 11.5, Anorihodes. 



Habitat. —Florida, May; District of Columbia, May and September; 

 Ohio. 



The type is in the National Museum. I have an uneasy suspicion 

 that this may prove to be Garadrina tarda Gn. The description ap- 

 plies fairly well, as I have recently found, but the species is certainly 

 no Garadrina. 



Genus ORTHODES Gn. 

 1852. Gn., Spec. Gen.,Noct.,i, 371. 



A monographic revision of the species is in the Proc. TJ. S. Nat. Mus., 

 XII, 469. The synonymy given by me there has been modified by an 

 examination of the types in the British Museum. 



O. crenulata Butler.* 



1890. Butler, Ann. &. Mag. Nat. Hist., G ser., vi, 97, Dyscliorista. 



hijinna var., Gn.

 1856. Wile, C. B. Mus., Het., x, 446, Ortlwdes. 



1874. Morr., Can. Ent., vr, 252, Ortlwdes. 



1875. Harv., Bull. Buff. Soc. Nat. Sci., iii, 9, Ortlwdes. 



Habitat. — Canada in June; New England and Middle States in 

 July and August; Missouri; Toxas in March, April, and May; Colorado. 



Mr. Butler was perfectly right in separating our North American 

 species. Guenee described his type from Brazil, and as var. A, men- 

 tions a specimen from New York. This is like what is in all American 

 collections, as infirma; but is specifically distinct from the Brazilian 

 specimens. Mr. Butler's type is in the British Museum. 



If Lederer's description of his genus Dyscliorista is entitled to any 

 weight at all, it is impossible that crenulata can be referred to it. Mr. 

 l^ntler has alloAved himself to be misled by a certain habital resem- 

 blance. 



O. cyiiica Gn.*

 1856. Wlk., C. B. Mus., Het., x, 443, Ortlwdes.
