Habitat. — Colorado, August to October; Nevada; Kansas; Ne-

This species is placed under Agrotis furcifera Wlk., in the British 



Museum collections, in my opinion erroneously. Mr. Walker has also 



described a specimen as Agrotis transversa, Avhich is almost certainly 



the same as Morrison's species. There are, however, several forms 



from Central or South America that come very close, and as careful 



and critical study would be required to decide specific limitations, for 



which I had not the time, I prefer leaving the name as it is, simply 



calling attention to the probabilities, and to the necessity for further 



study.
