have myself been niistiikon in ivgarding alternata as Califoniiuii 5 

 the variable Culifi)riiiau specimens, ill some of wliirh the oi-Iiicular 

 is open, belonging apparently to a distinct species Avliicli 1 have 

 described as cupidissima. 



AgTotis incivis Guenee. 



Mr. ^lorrison sends me a specimen of inv Anicla Alalamae as this 

 species, Avhicli is briefly described by Guenee, who makes no men- 

 tion of the exterior dotted line on the primaries. The name Anicla 

 may be used as a sectional one for the species which is, as I have 

 pointed out, essentially an Agrotis in its spinose tibiae, but appears 

 to differ by the smooth thorax, which is clothed with narrow scales 

 rather than hairs. I may have given too much Aveight to its 

 analogies with Laphygma. Mr. Morrison's simplicius and Guenee's 

 lubricans, are apparently related forms. 



Ag:rotis obeliscoides Guenee. 



I now believe that the species from the Eastern Slope, that I have 

 described as sexatilis, is the same with that described by Guenee in 

 the Species General under the above name. From California I have 

 received three specimens, under the number 30 (red label), from Mr. 

 Behrens. They differ by the narrower, more lunulate reniform. 

 The orbicular is variable in shape, Avhile the costal region is not 

 differentiated. I have a specimen of sexatilis from Colorado, and 

 these characters may be found to be inconstant over so Avide a 

 stretch of country. 



With regard to the question of " representative " species, I would 

 suggest that geographically separated forms in the Noctuidae exhibit 

 iisually some characters Avhicli enable the entomologist to judge of 

 the locality Avhence the material came. Thus California specimens 

 of A. dandcstina are paler, more distinctly marked than Eastern 

 ones. 



Agrotis Lewlsi Grote. 



This species, from Colorado, differs by the fore tibiae having 

 terminal longer s})ines and in the disc of the thorax shoAving a 

 ridge-shaped t uft . The ornamentation resembles A . obeliscoides, the
