Following his description of niveus Walsh2 says " that varieties occur in both sexes with legs and antennae almost entirely black " — characters which clearly designate nigri- cornis, while Riley3 in an early discussion of the same species states " that some specimens have a blackish ; Later Riley4 says that he considers fasciatus (nigricornis) a dark and rather well- marked variety of niveus, and in this article makes the same state- ment about nigricornis, which as a matter of fact is synonymous with the above fasciatus. Because the identities of these crickets were not clearly understood, there has been more or less confusion in subsequent literature as to the habits of these insects, which still persists, although to a much less degree than formerly. 1 First described as Gryttus niveus by De Geer.
