3. Ou a secoucl Collection of Lepidoptera made in Formosa 

 by H. E. Hobsoii; Esq. By Arthur G. Butler^ F.L.S., 

 F.Z.S., &c. 



[Received November 21, 1880.] 



it will be noticed, by a reference to my paper on Mv. Hobson's 

 first Collection (P. Z. S. 1877, pp. 810-816), that the Heterocerous 

 Lepidoptera were very poorly represented. On that account I wrote' 

 to Mr. Hobson, asking him to pay particular attention to the Moths, 

 the result of which was that we received in 1879 a small case, 

 containing; 334 Lepidoptera (chiefly Heterocera), collected atTakow'. 

 The following is an account of this series : —
