THE SKIN BEETLES. 597 



The extreme inflammability of benzine, and even its vapor, when 

 confined, should be remembered and fire carefully guarded against. 

 Where the floors are poorly constructed and the cracks are wide it 

 will be a good idea to fill the cracks with plaster of paris in a liquid 

 state; this will afterwards set and lessen the number of harboring 

 places for the insects. Before relaying the earpet tarred roofing 

 pa pel- should be laid upon the floor, at least around the edges, but 

 preferably over the entire surface, and when the carpet is relaid it 

 will be well to tack it down rather lightly, so that it can be occasion- 

 ally lifted at the edges and examined for the presence of the in- 

 sect."*

Posey County; rare. Beaten from flowers of Vratwyus. This 

 species is placed as a synonym of xa-oplnilariir by Jayne and Ilen- 

 shaw, but is very distinct. It was described from the "middle and 

 southern States" 30 years before the European species was known 

 from the eastern United States.

 Occurs especially on the flowers of the wheat-or corn-cockle. Lych- 

 nis githago Linn. It is also the most common and destructive of 

 museum pests, being especially injurious to skins of birds, mammals 

 and dried insects. If once infested, the only remedy is a teaspoon- 

 ful or two of bisulphide of carbon poured into the boxes or drawers 

 containing the specimens. They should then be closed as tightly as 

 possible. Naphthaline flakes, kept in liberal quantities in or about 

 the cabinet, will disguise the odor of the dried insects and repel the 

 pests, but they serve only as a preventative and not as a remedy
