372 PTEROPHORUS MICRODACTYLIA. 



The colour of the shining head is light yellowish- 

 brown, tinged with deeper brown on the crown of each 

 lobe, the ocelli and mouth darker brown again; the 

 body is of a slightly livid flesh-colour, becoming a 

 trifle paler and yellower on the three or four hinder 

 segments ; a distinctly paler dorsal line is visible, and 

 bisects both the bands of blackish rough poiuts, and 

 the anterior plate of them, though on this last it is a 

 mere fine thread ; the skin generally is smooth, and 

 glistens a little ; the spiracles are circular, a trifle 

 raised, wart-like, brown in colour, with a whitish 

 centre; above each spiracle is a wart-like tubercular 

 slight eminence ; on the sloping surface, in front of 

 the segments, are a pair of transversely-elongate oval 

 black-brown rough spots; the anal tip is dark brown. 



On the 2nd of August, I opened a stem and found 

 the pupa lying in a small cleared space just above the 

 middle of the mine, its head uppermost in a slanting 

 direction towards the entrance, its tail steadied by a 

 few threads spun on some frass, of which the mine 

 below was full; there was some also above, and a 

 little about the entrance, dry and mixed with silk. 



The pupa itself was a quarter of an inch long, 

 rather slender ; the thorax was rounded and well 

 defined, emitting a few bristly hairs, the head and 

 eyes rather prominent, the wing-covers long, the leg- 

 cases reaching to the penultimate abdominal ring, 

 from which they hung free ; on the abdomen were 

 subdorsal, lateral, and subspiracular rows of blunt 

 hook-like processes, in pairs, those on the last ring 

 the most projecting ; the whole surface is rather 

 glistening, and the colour a dark bronzy-green.
