260 BRITISH LEPIDOPTERA. 



a little darker; head dull green, the mouth and two lines receding 

 from it reddish-brown (Stainton). Frey writes: "Das Biiupchen 

 misst unter 2'" . Es hat eine grime Korperfarbe, einen grunlich- 

 braunen Kopf, braunrothe Mundtheile und davon ausgehend zwei 

 gleichfarbige Linien iiber das Kopfchen " (Linn. Ent., xi., p. 434). 

 The larva mines with the dorsum uppermost (Wood). 



COMPARISON OF THE LARVA AND MINE OF N. PRUNETORTJM WITH THOSE 

 OF N. PLAGICOLELLA. The larva of N. plat/icolella is yellow, and 

 makes a clear whitish blotch preceded by a slender gallery ; that of N. 

 prunetonun is green, and its mine is coiled like a watch-spring, after- 

 wards extending round the edge of the leaf. The frass fills up the 

 gallery, and makes it light brown (Threlfall). 



COCOON. The cocoon is pale or dark ochreous, not flossy, of rather 

 irregular oval form ; the pupa protrudes its anterior segments from the 

 cocoon previous to the appearance of the perfect insect (Stainton). 

 Frey says : " Der Cocon ist blass gelbroth, ganz flach und ziemlich 

 eckig." 



FOOD-PLANTS. Prunus spinosa. Prunus aviuiu (Frey), P. cerasus 

 (Hering). 



TIME OF APPEARANCE. The species is recorded as being only single- 

 brooded. Imagines emerged freely from June 5th-12th, 1882, from 

 larvae collected September 20th, 1881, at Witherslack ; larvae obtained 

 in same locality September 2nd, 1886 (Threlfall). Peyerimhoff says 

 that in Alsace the imago appears in April, from October larvae.
