Recent observations of Platysamia gloveri Str. have brought out some interesting facts on the varying length of hibernation periods. The gloveri moth is restricted almost entirely to the Rocky Mountain Region of the western United States. This implies in general, therefore, the ability to withstand subzero weather throughout the lengthy winter season.

Typical imitata from Vancouver Island and the southern interior of British Columbia is brownish in coloration with at times a slight purplish tinge. There is before me a specimen from Santa Barbara Co., Calif., in which the entire upper surface is definitely tinged with olive-green; this, in combination with a very indistinct type of maculation, gives it a decided mossy appearance. Genitalically it does not differ from the topotypical form. As it probably represents a race from the southern regions of California I give it the above name.

The Mallophaga listed were collected from birds and mammals in various parts of Oklahoma as indicated. Included in the records of the material collected by the author during the past three years are numerous records from material furnished by various students in the Entomology Department of Oklahoma A. and M. College. Previous records of lice taken from hosts in this state are very few, although there are numerous papers on species of this group found on birds and mammals of the states north and east of Oklahoma.
