224 BRITISH LEPIDOPTERA. 



Manual. It is, however, a trifle larger, and the tone of the colouring 

 is not quite so deep ; but the character that serves at once to dis- 

 tinguish it is the black head, that of N. reijiella being red. The larva, 

 mine, and food-plant are also quite different, and it is, besides, a single- 

 brooded species, the mines occurring in July (Wood). 



EGG-LAYING. The egg is laid on the under-side of a leaf of Pynis 

 torminalis, in an interspace between the ribs. 



MINE. The mine begins as a fine, straight gallery, then becomes 

 wide and twisting, almost widening into a blotch before its termination ; 

 the frass collected into a narrow central line. 



LARVA. Pale yellowish. Head blackish, sockets in which the 

 posterior lobes work, black, appearing as a pair of black spots behind 

 the head ; a row of linear brown marks down the middle of the 

 ventral surface, not noticeable when In the mine. 



COCOON. The cocoon is spun on the surface of dead leaves, etc., 

 lying on the ground. The shape of the cocoon reminds one of an 

 almond, and the resemblance is somewhat increased, when the cocoon 

 is examined under a two-thirds lens, by the loose, flossy, silken 

 covering by which the cocoon proper is surrounded. The end of the 

 cocoon from which the pupa emerges is much broader than its nadir. 

 In colour it is of a rather bright orange-brown tint, with a considerable 

 range of variation, some being more inclined to brown, others to 

 orange. The main structure is fairly closely woven, and moderately 

 smooth, but with a loose, flossy, silken outer covering enveloping it. 

 This loose silk is particularly abundant on the upper surface, where it 

 sometimes forms a conspicuous bunch. The empty pupa-case projects 

 from the cocoon to about the 4th or 5th abdominal segment. 

 [Described June 9th, under a two-thirds lens, from cocoons sent by 

 Dr. Wood.] 



PUPA. The chitin of the pupa-case is exceedingly delicate and 

 fragile, transparent, slightly amber in tint, but colourless on the raised 

 portions of the appendages and segments. 



FOOD-PLANT. Pynis torminalis. 



TIME OF APPEARANCE. The species is single-brooded, the imagines 

 appearing in May and the beginning of June, from larvae collected 

 the previous July. 



LOCALITIES. HEREFORD : Tarrington, confined to a small corner of one 

 wood, where it is fairly common, nearly every bush of its food-plant having a few 

 tenanted leaves, with occasionally two or even three mines in a leaf (Wood).
