Anthrenus is a terrible pest, and unless the utmost vigilance 
is exercised they will get into and ruin an insect collection in a 
short time. The strong fumes of napthaline or crude carbolic 
acid will disguise the odor of dried insects and repell the pests 
from the boxes. Strong carbon bi-sulphide fumes will kill An- 
threnus after they get in. Maj. Casey has a synopsis in Journal 
N.Y: Ent2Soc,, June, 1900: 
HISTERIDZ:: 
Our species are nearly all black shining beetles that live ia 
excrement and decaying material. Some few species live under 
bark and are modified for such an existence being flattened and 
with short legs.
