In the examination of my last season's collections of Hypena scabra (scabralis, Guen.,) and “H. erectalis,” for sexual determinations, I was surprised to find of the former, only the male represented. and of the latter, only the female. Collections of each having been made during the same period of time (from September 1st to September 24th) and at the same place (the wall and ceiling of the piazza of my residence)– such a remarkable occurrrence seemed to be so removed from accident, and inexplicable from any difference of sexual habits, that I was led to suspect the identity of the two species.

During the latter part of this month ans early June those who have grape vines under their charge are often annoyed at finding the terminal leaves of the young and tender branches tied by means of silken threads into a sort of ball shaped mass, and within the hollow sphere thus formed is found a small whitish hairy caterpillar, which feasts on the tender leaves ans young blossom bunches. Usually but a single occupant is found in each enclosure, but occasionally we have found two, and, in one instance, three.
