T. melanorhinus Big. I have a specimen from north-eastern Oregon which I suspect is the male of this species although the red on the sides of the abdomen is much more extensive than I have observed in any female (see Philip, 1936) involving the first four tergites and most of the venter, the rows of pale spots only suggested as a pale pollinosity in this sex.

I employ this subfamily name as used hy Hampson although I believe that in all probability it must be restricted to the genus Acronicta Ochs. and its few close allies, and the term Ampphipyrinae, as used by Seitz in his Macrolepidoptera of the World, employed in its place.

One does not usually associate springtails with snakes. Nevertheless a snake was indirectly responsible for the discovery of the first North American representative of the interesting and peculiar Collembolan genus Oncopodura. In 1932 Professor J. E. Guthrie received a snake from Mr. O. C. Van Hyning of Marianna, Florida, mailed alive in moss. Instead of discarding the moss, Professor Guthrie requested that its Arthropod fauna be extracted.
