EMMELESIA UNIEASCIATA. 11 



carefully as possible, found it stowed away in one of 

 them ; but, instead of being increased in bulk, look- 

 ing shrivelled, and much thinner than when last seen. 

 This was disappointing; but, taking comfort at the 

 thought that more tender diet might suit it better, I 

 asked Mr. Buckler to get some of the greenest pods he 

 could find, and soon discovered that they were just 

 what was wanted. On the 16th of October I found 

 my larva in the act of moulting within a seed-pod, 

 and after this, its last moult, a great change took 

 place in its appearance and manner of life. 



About this time, too, Mr. Bryant, having at Mr. 

 Buckler's instigation searched carefully the Bartsla 

 plants in his locality, found several larvae feeding at 

 large ; and, as those which he kindly sent to Mr. 

 Buckler exactly corresponded with the one I had 

 reared, there was no difficulty in identifying their 

 species ; and from these, together with my own soli- 

 tary specimen, the following account and descriptions 

 have been drawn up. 



The egg is laid in August, and the larva soon 

 hatched. 



Perhaps it feeds first inside the flowers of the 

 Bartsla, but, at all events, we know that, whilst 

 young, it lives within the unripe seed-pods, which it 

 enters by a hole in the side, remaining hidden until 

 all the seeds are consumed, the frass at the entrance 

 hole alone showing its whereabouts. After its last 

 moult it no longer hides itself, and seems to have no 

 difficulty with the ripening capsules and seeds, still 

 making a hole as before in the side, and inserting its 

 head and front segments as far as it finds it 

 necessary to get at the seeds, all the while holding 

 on with its prolegs to the stem outside. It seems 

 to become full-fed towards the end of October, 

 and goes just under the surface of the ground for 

 pupation. 



The simultaneous change of habit and ornamenta- 

 tion at the last moult is very interesting, but I will
