HABITATIONS OF INSECTS. 461 



Von Scheven to Bombyx vestita, F. ; which Ochsenheimer 

 regards as synonymous with Psyche graminella, while P. 

 Fidelia of the Wiener Verzeichniss, covers itself with short 

 portions 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 (P. graminella, Och- 

 senh. just named), is composed of squarish pieces of the 

 leaves of grass fastened only at one end, and overwrap- 

 ping each other like the tiles of a house ; and that of 

 another noticed by the same author, of portions of the 

 smallest twigs of broom arranged on the same plan a . 

 Indeed the larvae of the whole of this tribe of moths, 

 now separated into a distinct genus (Psyche, Schrank, 

 Ochsenh., Fumea, Ha worth), but which according to 

 Germar needs further subdivision, reside in cases or 

 sacks (whence they are called by the Germans Sacktragen) 

 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 ob- 

 servations 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 species of Cryptocephalus, (C. duodecimpunctatus) 

 differing in this respect from all other known Coleoptera, 

 live in moveable cases 5 . I have however found a spe- 



in the Naturforscher Stk. xx. 61, &c. also a valuable paper by 

 Dr. Zinckeng enannt Sommer,in Germar's Mag. fur Ent.'i. 19 40.
