23. Agrotis hilitura. 



Agrotis hilitura, Guenee, Noct., i., p. 285, n. 467 

 (1852).

 vii., p. 74, n. 3 (1854). 



Agrotis deprivata, Walker, Cat. Lep. Het., xi., p. 739 

 (1857). 



The example described by M. Guenee was evidently 

 somewhat rubbed, so that nothing remained of the 

 markings excepting the two short blackish streaks, one 

 between the discoidal spots, the other close to the base 

 of interno-median area, of primaries. In many examples 

 only the discoidal streak is present, and therefore it 

 is open to question whether the name proposed by M. 

 Blanchard should not be preferred, though his description 

 would do almost equally well for the variety of A. 

 hispidula with white secondaries. 



24. Agrotis anteposita. 



Agrotis anteposita, Guenee, Noct., i., p. 273, n. 449

The N. lutescens of Blanchard is evidently the variety 

 with yellowish primaries ; the colour of these wings 

 varies from dark fuliginous to sordid stramineous ; every 

 gradation between the extremes is to be seen in a good 

 series such as I have before me, but the darker forms 

 are all females and the lighter males. 



25. Agrotis americana. 



Luperina americana, Blanchard, in Gay's * Faiina 

 Chilena,' vii., p. 77, n. 1 ; pi. 4, fig. 8 (1854).

This is the only Noctuid figured by Blanchard, the 

 representation of which is fairly recognisable ; many of
