LEPIDOPTEROUS INSECTS. ol 
B. Wings pendant ; labial palpi much longer than the head, and 
thrown backwards above the thorax. 
It has but one genus, Gcornora. 
2. Tongue very short, or almost none ; a tuft of scales or hairs 
on the head. 
A. Labial palpi large, projecting. 
The genera are Evprocampus, Pavers. 
B. Labial palpi small, not projecting. 
It consists but of one genus, Tinea, 
II. Antenne (very long) and eyes almost contiguous. 
Ts has but one genus, Aveta. 
Genus Trvza, Latreille. 
The antenne are setaccous, simple or ciliated, dis- 
tant ; wings linear, rolled around the body ; 
proboscis very short, or none; having two short 
hairy cylindrical palpi; a tuft of scales on the 
front. 
The insects of this genus and its congeners are very destruc- 
tive to woollen cloths and furs. Inclosed in a tube, composed 
of the materials in which they are found, the caterpillars per- 
forate, eat, and digest these substances. At the commencement 
of spring they change into pups, and remain in this form about 
twenty days. After coupling, the female deposits her ova in 
the substances upon which the young are afterwards to feed, 
and the caterpillars are hatched in fifteen days after. Many 
means have been proposed to prevent the ravages of these 
small inseets ; but the most effectual is oil of turpentine. A 
piece of cloth or paper saturated with this oil, and placed in 
the trunks, closets, or wardrobes, to be protected from their 
depredations, soon kills them. A solution of corrosive subli- 
mate and spirit of wine is also found to be an effectual preven-
