102 PAMPHILIUS INAN1TUS. 



Antennae yellow at base, the rest black, more or less testaceous beneath. 

 "Wings hyaline. Nervures blackish ; stigma testaceous ; the apex black. 



The $ has the head for the greater part yellow beneath, entirely 

 black above ; the breast is for the most part yellow, as is also the ventral 

 surface ; the basal two or three segments are black above, and the 

 apical three or four segments are fulvous, like the middle segments. 



Length 5 lines. 



A widely distributed species, found frequently in 

 gardens. The larva lives on roses, on the leaves of which 

 it forms a portable case, not unlike that made by the 

 Caddice worms. According to Giraud (1. c.) the case 

 " forms a somewhat conical tube, open at both ends ; 

 its length varies according to the age of the larva, and 

 sometimes is 5 cm. It is formed of a variable number 

 of straight and longish folds, detached from the edge 

 of the leaf, rolled in a spiral, and imbricated the one 

 on the other in such a way that the border of the fold 

 formed by that of the leaf is found always above and 

 beneath, while the opposite edge, which is without 

 asperities, is found more directly in connection with 

 the larva. Some silken threads serve to fix all the 

 spirals together. As the larva grows, it lengthens its 

 tube by adding to it a fresh piece, enlarging it at the 

 same time. It is in this protecting tube that the larva 

 lives, entirely hidden, except when it wishes to search 

 for its food or change its position. In the first case, 

 it releases the half or the three-fourths of its body to 

 reach the part of the leaf it wishes to devour. Should 

 it wish to reach a neighbouring point, it detaches itself 

 from the sack so that only the anal extremity remains 

 attached to it; it throws then some silken threads 

 between the orifice of the sack and the point it wishes 

 to attain ; then fixing its feet on this point, it brings 

 back quickly its body along with the tube, surmount- 

 ing thus all the obstacles that might result from the 

 interlacing of the leaves and the tube. This progres- 

 sion, although laborious, nevertheless not only enables 

 it to change from one leaf to another, but even from 

 branch to branch. Like all its allies it is very timid, 

 the least movement frightening it and making it re-
