126 Mr. A. G. Butler on Heterocerous Lepidoptera 



disco -cellular spot of secondaries (wliich is black), very 

 indistinct ; venter sericeous, with slight pink reflections. 

 Expanse of wings, 33 mm.

 February."— r. E. 



This species is apparently commoner than the pre- 

 ceding, with which it was associated by Mr. Edmonds ; 

 there cannot be any doubt of its distinctness : it may 

 possibly be the species intended by M. Blanchard's very 

 imperfect description of Hadena povera, but the white 

 line across the primaries can hardly be the dark trans- 

 verse line of that description — " hacia la extremidad una 

 raya transversal 6 una hilera de manchitas ohscuras," 

 unless the word "obscuras" is intended to apply to 

 the spots alone. 



NOCTUID^. 

 Agrotis, Ochs. 



18. Agrotis suffusa. 



Phalcena-Noctua suffusa, Gmelin, ed. Syst. Nat., i., 5, 



p. 2541, n. 1028. 

 Noctua rohusta, Blanchard, in Gay's ' Fauna Chilena,' 



vii., p. 75, n. 1 ; pi. 6, fig. 9 (1854). 



This common species does not vary from European 

 examples in Chili : what could have induced M. Blanchard 

 to rename it, it would indeed be difficult to say. 



19. Agrotis saucia. 



Noctua saucia, Hiibner, Samml. Europ. Schmett. Noct., 



fig. 378 (1793—1827). 

 Var. Agrotis ambrosioides, Walker, Cat. Lep. Het., xi., 



p. 738 (1857). 

 Var. Spcelotis stictica, Blanchard, in Gay's ' Fauna 



Chilena,' vii., p. 73, n. 1 ; pi. 6, fig. 8 (1854). 

 Agrotis impacta, Walker, Cat. Lep. Het., x., p. 337, 



n. 71 (1856). 



With the typical form is also the slight variet}^ figured 

 by Hiibner under the name of N. ceqtia, but which hardly 

 differs sufficiently to need the separate line and brief 

 description given to it by Staudinger ; the form named 

 by Walker A. ambrosioides, though it has the primaries 

 of the latter slight variety, differs entirely in the colora-
