204 LEPIDOPTERA. 



shining ; dorsal plate slightly greener ; raised dots white- 

 yellow, very minute. 



May and June on maple and sycamore, in loaves longi- 

 tudinally rolled. Kosslin says that it first feeds on the 

 flowers. 



Pupa pale yellow — of the same colour as the larva and imago 

 — wing-covers of a somewhat richer tint. Between the 

 halves of a folded leaf of the food plant in a shining white 

 silken cocoon. 



The moth is of a somewhat sluggish temperament ; sits 

 during the day often upon a leaf of maple or sycamore, from 

 which it may be boxed, or if disturbed flies down in a 

 curve but a very short distance. Not uncommon in gardens 

 in the London suburbs among sycamore. Moderately 

 common throughout the Southern counties of England, 

 though more particularly frequenting maple ; apparently 

 rare in the Midlands, but frequent in the Eastern and 

 Western counties, and in Yorkshire. Lancashire, Cumber- 

 land, Durham, and Northumberland, yet I find no satis- 

 factory record for Scotland or Ireland. In Wales I have 

 taken it in Pembrokeshire. Abroad it is found through the 

 greater part of Central Europe, and also in Livonia, Scandi- 

 navia, Italy, and Greece.
