476 INSECTA. 



portions of leaves laid one over the other, and forming 1 a sort of flounce ; 

 others are in the form of a bat, and sometimes dentated along one of their 

 sides. The material of some of them is diaphanous, and as if cellular or 

 divided by scales. 



The caterpillars of the true Tinese, commonly called Moths, clothe them- 

 selves with particles of woollen stuffs, which they cut with their jaws and 

 on which they feed, hairs of furs, and those of the skins of animals in zoolo- 

 gical collections, united by silk. They know how to lengthen their sheath, 

 or to increase its diameter by slitting it and adding a new piece. In these 

 tubes they undergo their metamorphosis, after closing the orifices with silk. 



The Pseudo-Tinex content themselves with mining the interior of the 

 vegetable and animal substances on which they feed, and forming simple 

 galleries, or if they construct sheaths either with those matters or silk, they 

 are always fixed, and are mere places of retreat. 



These caterpillars, which perforate in various directions the parenchyma 

 of the leaves on which they feed, have been called Miners. They produce 

 those desiccated spaces in the form of spots and undulating lines, frequently 

 observed on leaves. Buds, fruits, and seeds of plants, frequently those of 

 wheat, and even the resinous galls of certain Coniferse, serve for aliment 

 and habitations to others. These Insects are frequently ornamented with 

 the most brilliant colours. In several species the superior wings are deco- 

 rated with golden or silver spots, sometimes even in relief. 



AGLOSSA, Lat. 



Where the four palpi are exposed, and the wings form a flattened triangle; 

 there is no emargination in the extremity of the upper one. 



A. pinguinalis. Superior wings agate-grey, with blackish stripes and 

 sp'ots. Found in houses on the walls. 



.. Its^caterpillar is naked, blackish-brown, glossy, and feeds on fatty or bu. 

 ^tyjrfceous substances. Reaumur called it the Fausseteigne-des cuirs, be- 

 cause it also feeds on leather and the covers of books. It constructs a tube 

 which it places against the body on which it feeds, and covers it with gra- 

 nules. 



GALLEUIA, Fab. 



Where the scales of the clypeus form a projection that covers the palpi; 

 and the superior wings, proportionally narrower than in Aglossa, and emargin- 

 ated in the posterior edge, are, as well as the inferior ones, strongly inclined 

 and turned up posteriorly like the tail of a cock, as in many species of the 

 following subgenera. 



O. cereana, Fab. About five lines in length; cinereous; head and thorax 

 paler, and little brown spots along the internal margin of the superior wings. 



Reaumur designates its caterpillar by the name of fausse-teigne ds la cire, 

 It ravages hives by penetrating into the combs, constructing, as it pro. 

 gresses, a silken tube covered with granules, which are formed of the wax
