XXIII. On the Lepldoptcra of the Family Lithosiidae, 

 in the Collection of the British Museum. By 

 Arthur G. Butler, F.L.S., F.Z.S., &c. 



[Read October 3rJ, 1877.] 



My object in the publication of tbe present paper is to 

 make a list of the species of Litliosiidce at present existini^ 

 in the National Collection, at the same time correcting- 

 the numerous erroneous determniations, chiefly with refer- 

 ence to genera, in Mr. AValker's lists ; in order to do this 

 satisfactorily, I have continued my studies in the Aving 

 veining of the species, but chiefly confining myself to that 

 of the secondaries, which has, to a great extent, enabled 

 me satisfactorily to locate them in their proper genera. 



Owing to the affinity which appears to exist between 

 some of the smaller Lithosiids and some genera of Tineites, 

 I feel some compunction in admitting them into this paper; 

 still I think on the whole they are better where they are, 

 unless they can be proved, by breeding, to belong to the 

 HyponomeiLtid<B ; I refer to such genera as Talara and 

 Trichromia, which seem not only allied to the Lithosiid 

 genus Cisthene, but less closely to Atteva = Corinea, 

 Cydosia, ike. of the HyponomeutidcB. 



The genus McBpha, referred by Walker to the Tineites, 

 appears to be allied to Cisthene. 



Family LITHOSIID^E.

1. C. magnifica, Wlk. Lep. Het. Suppl. 1, p. 96. H(d). — 

 Bogota. 

 This species has no structural ])oints in common with 

 the thx'ce forms of Eupyra, to which Walker first applied 

 the seneric name. 



• Tliis generic name cannot he retained as orijiiiially applied. I Iiave, 

 therefore, adopted it for C. magnijica only, using Walker's extension of 

 the group.
