elongate and flattened form, very dark colour, and by there being a depression on the 
base of the thorax on each side. Iam unable to distinguish East-Siberian individuals 
from our small Mexican series, and Erichson? has stated that D. domesticus, Gebl., 
from Siberia, is the same as D. cadaverinus.

This is one of the more extensive of the genera of Dermestide, and is numerous in 
species in the Eastern Hemisphere. It includes the more imperfect forms of the 
subfamily, and there is considerable variety in minor points of structure. I have not 
thought it necessary to adopt Casey’s division of the North-American forms at present, 
as the material available does not enable me to verify his characters.

in N. America.

Three specimens, considered by Dr. Horn to be probably this species. Jayne’s 
description is marred by an error that renders it nugatory. If, however, in his second 
description of the elytra, we read “black” instead of “rufous,” this would bring it into 
accord with his immediately preceding statement, and would apply to our insect. 
According to Casey, the antenne are only 10-jointed in the male.
