MIANA LITEROSA. 101 



The first egg hatched September 9th. The young 

 larva was rather slender in proportion, its colour pale 

 brownish flesh-colour, and very highly polished ; the 

 head dark blackish-brown, a paler dark brown plate 

 on the second segment, and another on the anal flap. 

 (W. B., Note Book I, 133.) 



On the 1st of June, 1880, five larvse from Mr. J. 

 Gardner, of Hartlepool, came ; they were in the stems 

 of Dactylis glomerata and some other grass. The 

 sign of the presence of a larva in a stem is that the 

 stem turns white and shows conspicuously amongst 

 the sound green stems. The full-grown larva is from 

 three-quarters to seven-eighths of an inch in length, 

 stoutest at the fourth segment, tapering thence to the 

 head, and also very gradually to the anal segment. 



On the 7th of June, 1880, I received from the Rev. 

 Charles R. Digby, of Studland Rectory, parts of an 

 immature flowering stem with flower end of Iris 

 foetidissima, in which a larva, seven-eighths of an inch 

 long, of literosa was feeding, a second larva having 

 escaped from the holes made in the box. 



The ground colour of this individual was light 

 ochreous-yellow, with scarcely any tinge of greenish ; 

 the space between the dorsal and subdorsal lines was 

 brighter pink than usual, forming two broad stripes 

 of that colour. When the larva was walking the 

 wrinkles on the back would open and show off the 

 ground colour, but on contraction they would shrink 

 together, and thus form a darker pink on the pink 

 parts. The plate on the second segment was light 

 brown, edged in front with darker brown. 



This larva spun up within the shrivelling remains 

 of the flower bud it had eaten out, in a thin silken 

 cocoon, and the moth emerged on the 24th of July. 



The pupa, half an inch long, was decidedly stout 

 in proportion, the thorax and wing-covers well deve- 

 loped, tapering a little towards the anal tip, which was 

 furnished with two slightly diverging points, and sur- 

 rounded with four very minute curly -topped bristles ;
