660 Mr. A. G. Butler's further notes on the 



" Leucania'' disjuncta, Walker, is an Agrotis ; L. 

 propria and L. semivittata must be transferred to Onima- 

 tostola.

This is proved, by a comparison of the types, to be 

 the Heliopliila ligata of Grote. 



11. Leucania iusueta.

Allied to L. coinnia. The type only differs from that 

 of L. adonea, Grote, in the less distinctly whitish costal 

 border and veins of primaries : it is quite possible that 

 they may prove to be forms of the same species, but I 

 would always rather err on the side of allowing too 

 many species to stand rather than too few ; it is always 

 easy to put things together, but it often requires careful 

 study to discriminate between closely-allied species. 



12. Leucania Unita. 



Leucania Unita, Guenee, Noct., i., p. 81, n. 114 (1852). 

 L. insecuta, Walker, Lep. Het., Suppl., 2, p. 625 



(1865). 

 L. intermissa, Walker, I. c., p. 626. 



United States and Shanghai. 



This is also identical with L. amygdalina, Harvey. 

 The Shanghai specimens are indistinguishable from the 

 American. I have already pointed out (Trans. Ent. Soc. 

 Lond., 1882, p. 113) that L. decolorata of Blanchard is 

 only a pale form of L. imjmncta, Guen. 



'• L. pallens " of the United States agrees absolutely 

 with the European L. siraminca. The two forms have 

 practically the same characters, and if received from any 

 extra-European locality would never have been con- 

 sidered distinct ; indeed, it is possible to lind examples 

 which cannot with certainty be referred to one form
