464 HABITATIONS OF INSECTS. 



larvae of a moth referred by Von Scheven to Bomhyx 

 vestita, F. ; while Tinea Viciella of the Wiener Ver- 

 zeichniss 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, described and figured 

 by Reaumur (Psj/cJte graminella, Ochsen.), is com- 

 posed 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 noticed by the 

 same author, of portions of the smallest twigs of broom 

 arranged on the same plan^. Indeed the larvae of the 

 whole of this tribe of moths, now separated into a di- 

 stinct genus (Psj/che, 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 Sackfrager) composed of silk, 

 and fragments of grass, bark, &c. 



The larvae of a small beetle {CJi/tra longimana) re- 

 side in oviform cases apparently of a calcareous or 

 earthy substance, joined by a gummy cement and co- 

 vered with red hairs, the origin of which, Hiibner, 

 who first discovered them, could not account for: and 

 from the observations of Amstein and the French trans- 

 lator of Fuessly's Archives, it seems probable that the 

 larvae of all the species of Clijtra, and according to 

 Zscliorn, at least of one species of Cryptocephalus, 



inateiialb. Sec the excellent elucidation of the history of (his tribe, 

 whose mode of generation is so singular, by Von Scheven, in the Ma'ttr- 

 forscher Stk. xx. 61 , &c.: also a valuable paper by Dr. Zinkr, gcnaiint
