TINEA. INSECTS. 369 



cylindrical, or narrow and elongated ; labial palpi in some 

 short, almost cylindrical, in others thrown backwards in the 

 form of horns ; antennae generally simple. 



The insects of this tribe are very small, but often ornamented with brilliant co- 

 lours. The margin of their wings is fringed. The caterpillars have generally six- 

 teen feet, and they live under cover, some in tubes, which they fabricate, and others, 

 which have in consequence received the name of miners, in galleries formed in the 

 interior of leaves. The species which destroy woollen cloths, furs, &c. are in port- 

 able tubes. The miners furrow the parenchyma of leaves, and are sometimes very 

 destructive to fruits and seeds. 



I. Antennas and eyes separated. 



1. A distinct and elongated spiral trunk. 



A. Wings resting horizontally on the body, or forming a rounded slope ; labial palpi 

 not longer than the head.

 Gen. ADELA. 



Gen. TINEA, Lat. Phalcena, Lin. 



Antennae setaceous, simple or ciliated, distant; wings linear, roll- 

 ed around the body ; trunk very short or none ; two short 

 hairy cylindrical palpi ; a tuft of scales on the front. 



The insects of this genus are very destructive, particularly to woollen cloths and 

 furs. Inclosed in their tube, composed of the materials in which they are found, 

 the caterpillars perforate, eat, and digest these substances. At the commencement of 

 spring they change into pupae, and remain in this form about twenty days. After coup- 

 ling, the female deposits her ova in the substances upon which the young are after- 

 wards 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 ef- 

 fectual is oil of turpentine. A piece of cloth or paper saturated with this oil, and 

 placed in the trunks, presses, or wardrobes, to be protected from their depredations, 

 soon kills them. Spirit of wine or tobacco smoke are equally effectual ; but the one 

 soon evaporates, and the application of the other is difficult.
