B. Wings pendant ; labial palpi much longer than the head, and 



thrown backwards above the thorax. 

 It has but one genus, (ECOPHORA. 

 2. Tongue very short, or almost none ; a tuft of scales or hairs 



on the head. 



A. Labial palpi large, projecting. 



The genera are EUPLOCAMPUS, PHYCIS. 



B. Labial palpi small, not projecting. 



It consists but of one genus, TINEA. 

 II. Antenna) (very long) and eyes almost contiguous. 

 Is has but one genus, ADELA.

 The antennae are setaceous, simple or ciliated, dis- 

 tant ; wings linear, rolled around the body ;

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 pupae, 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 insects ; 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-
