of this area, the upper epidermis is left intact, but there is no 

 evidence that the larva is a miner at any stage. Farther out 

 in the same area, holes are made but often a fragment of the 

 upper epidermis is left. During this time the larva has been 

 increasing the extent of its web, which however remains 

 densest near its beginning, toward which it retreats when dis- 

 turbed. Toward the outer edges of the web the larva then 

 blocks out the area next to be consumed, thus : a narrow line 

 leaving the upper epidermis intact is cut through the lower

epidermis and leaf substance, enclosing thereby an irregular 

 oval or circular space (&). In the portion of this space first 

 consumed, a small piece of upper epidermis is left, which 

 soon becomes brownish and shriveled. In the rest of the 

 oval space the entire substance is eaten (c). The earliest if 

 such areas are usually small ; there may be three or four simi- 

 lar holes, each larger than the preceding (c). The web is ex- 

 tended outwardly in a thin sheet to reach each of these spots 

 (c). At maturity the web is thickened near the angle and 

 drawn into an oval cocoon-like mass, within which the char- 

 acteristic short and broad flattened pupa is formed. The 

 imagos appeared July 11-18. 



There is a second generation late in the summer which pro- 

 duces imagos the following spring.
