introduces itself under the epidermis. Directing itself towards 

 the petiole, it mines a long and straight gallery the length of the 



nerve. The cast skin which it de-

taches is extremely fine, shining and 

 silvery, resembling the trace ot a 

 slug. The pale redish-brown ex- 

 crement is scattered in the mine. 

 Arriving at the petiole, the larva 

 ascends near the edge and suddenly 

 enlarges its mine in the form of a 

 plate, and the edge of the leaf is curved up and rolled. Soon it 

 is no longer contented with ruminating in the leaf, and attacks it

in June (in August in France). The larva continues to feed upon 

 the edges of the leaf that are rolled into the interior of its conical 

 home. About June 15 the larva reaches ma- 

 turity, and is then from 8-10 mm. long, and of 

 a light yellowish flesh color, greenish dorsally, 

 the head a little darker than the body, and the 

 mouth-parts brownish. It has four pairs of 

 pro-legs borne by the third, fourth, fifth and 

 tenth abdominal segments. The segments are 

 considerably wrinkled, and the whole body is 

 sparsely clothed with quite long whitish hairs. 

 In its preparation to transform one must ad- 

 mire the larva's foresight and intelligence. It 

 first eats almost through the leaf over a small round area, taking 

 care to leave only the outer epidermis of the leaf, and thus forms
