The 



egg is a small 



with the rollings, in the former place on June 15, 1895, and on 

 June 20, 1896. 



The work of the female beetle is very easily recognised in the 

 form of " thimble 

 cases," constructed 

 by rolling up the 

 oak (or, more rarely, 

 Spanish chestnut) 

 leaves (fig. 65). 

 These are chiefly 

 found on young 

 shoots, growing as 

 underwood. On un- 

 rolling the cases 

 on the dates men- 

 tioned, a single egg was found in each case 

 spherical body, of an orange colour. 



The perfect beetle (fig. 66) is about 6 mm. long, of a bright 

 rufous-brown colour ; thorax and elytra smooth ; legs all black 

 and shining; antennae, black and 12- 

 jointed ; head black, and eyes of a 

 chocolate colour. 



DEPOUAtJS BETULtE (L.) 



This species of leaf-rolling beetle is 

 abundant in many parts of the country, 

 but I have found it most plentifully at 

 Kielder, Northumberland. The leaves 

 (of birch) are cut much in the same 

 manner as by the preceding species, but 

 the case is rolled lengthwise instead 

 of in a globular form (fig. 67). The 

 rolled portion somewhat resembles a 

 kind of paper bag used by grocers or 

 confectioners, and made by rolling a square-cut piece of paper round 

 the hand. The chief injuries are done by the female insect : she 

 interferes only with the vitality of a certain portion of the leaf. She 

 begins rolling operations by making an incision on the outer edge of
