464> HABITATIONS OF INSECTS. 



Von Scheven to Bombyx vestita, F. ; while Tinea Fidelia 

 of the Wiener Verzeichniss covers itself with short por- 

 tions of the stems of grasses placed transversely, and 

 united by means of silk into a five- or six-sided case. 

 The habitation of a third larva of the same family, de- 

 scribed and figured by Reaumur {Psyche graminella, 

 Ochsenh.), is composed of squarish pieces of the leaves 

 of grass fastened only at one end, and overwrapping each 

 other like the tiles of a house ; and that of another no- 

 ticed by the same author, of portions of the smallest 

 twigs of broom arranged on the same plan 3 . Indeed 

 the larvae of the whole of this tribe of moths, now sepa- 

 rated into a distinct genus {Psyche, Schrank, Ochsenh., 

 Fumea, Haworth), but which according to Germar needs 

 further subdivision, reside in cases or sacks*(whence they 

 are called by the Germans SacMrager) composed of silk, 

 and fragments of grass, bark, &c. 



The larvae of a small beetle {Clytra longimana) reside 

 in oviform cases apparently of a calcareous or earthy 

 substance, joined by a gummy cement and covered with 

 red hairs, the origin of which, Hiibner, who first disco- 

 vered them, could not account for : and from the obser- 

 vations of Amstein and the French translator of Fuessly's 

 Archives, it seems probable that the larvae of all the species 

 of Clytra, and according to Zschorn, at least of one spe- 

 cies of Cryptocephalus, (C duodecimpunctata, F.) differ- 



light materials. See the excellent elucidation of the history of this 

 tribe, whose mode of generation is so singular, by Von Scheven, in 

 the Naturforscher Stk. xx. 61, &c. : also a valuable paper by Dr. Zinc- 

 ken, genannt Sommer, in Germar' s Mag. fur Ent. i. 19—40.
