308 INSECTA. 



The caterpillar lives on cloth, and other woollens, weaving 

 with their detached particles mixed with silk, a portable tube ; 

 it lengthens it at one end in proportion as it grows, and slits it 

 to increase its diameter, by adding another piece. Its faeces 

 have the colour of the wool on which it feeds. 



T. pellionella. Fab. ; Reaum,, Insect., Ill, vi, 12 — 16. Upper 

 wings Silver grey, with one or two black dots on each. 



The caterpillar inhabits a felted tube on furs ; it cuts the 

 hairs at base, and rapidly destroys them. The 



T. flavifrontella. Fab., ravages cabinets of natural history in 

 the same way *. 



T. graneila. Fab. ; Roes., Ins. I, Class IV, Pap. Noct., xii. 

 Its upper wings are marbled with grey, brown and black, and 

 turned up posteriorly. 



The caterpillar — fausse-teigne des bles — connects several 

 grains of wheat with silk, and forms a tube, from Avhich it 

 cccasionally issues to feed upon those seeds. It is very noxious. 



Ilithyia, Lat. — Crambus, Fab-^ 

 Where the proboscis is very distinct, and of an ordinary size, and 

 the last joint of the inferior palpi is manifestly sliorter than the pre- 

 ceding one f. 



Yponomeuta, Lat., 

 Where the proboscis is also very distinct, and of an ordinary size ; 

 but the last joint of the inferior palpi is at least almost as long as the 

 preceding. 



These Insects seem to be connected with the Lithosiae. 



Y. evonymella; Tinea evonymella. Fab. ; Roes., Ins., I, Class. 

 IV, Pap. Noct., viii. Superior Avings glossy-white, with nu- 

 merous black points ; inferior ones blackish. 



Y. padella; Tinea padella. Fab.; Roes., Ibid., viii. Supe- 

 rior wings lead-grey, Avith about twenty black dots. 



The caterpillar, like that of the evonymella, lives in society, 

 forming a numerous community under a web. It is sometimes 

 so abundant on the fruit trees in Europe, the leaves of which it 

 devours, that the branches seem to be covered with crape \. 

 In the following subgenus, or the 



CEcopHORA, Lat., 

 The inferior palpi are covered over the head like horns, taper to a 

 point, and even extend to the back of the thorax. 



The Teigne des hli'S, which is so destructive in the southern 

 departments of France, and of a uniform brownish cream- 

 colour, belongs to this subgenus. 



* AH the authors who have described or figured Tineites, and other analogous 

 Lepidoptera, having paid but little attention to exactness, we find it impossible to 

 refer most of the species mentioned by them to our various subgenera. 



t Crambus canieus, Fab., and some other species. The antennse of the males are 

 marked iuferiorly by a knot-like inflation.
