260 BRITISH LEPlDOPTERA. 



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

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

 misst unter 2'" . Es hat eine griine Korperfarbe, einen griinlich- 

 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. prunetorum with those 

 of N. plagicolella.— The larva of N. plaf/icolella is yellow, and 

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

 prunetorum 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. — Primus spinosa. Primus avium (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.
