150 LEMIODES PULVERALTS. 



On the 17th I observed that they had taken to the 

 under-sides of the leaves of the mint {Mentha hirsuta, 

 of which Mr. Webb had previously sent me a plant to 

 pot, in readiness for them), and had acquired a light 

 greenish tinge rather inclining to drab, but quite 

 translucent. They were eating out little hollows from 

 the under surface, and leaving little heaps of black 

 frass. 



On the 26th, after their second moult, their heads 

 and plates were light brown and shining, their 

 bodies brownish and semi-transparent beneath, though 

 without gloss. 



On the 29th only two were alive, one of which lay 

 in a small silken hammock-like web spun beneath the 

 hairs of a leaf (on the under-side), and the larva seemed 

 to be an eighth of an inch long, and apparently 

 preparing for its third moult; the other, about the 

 same size, was actively crawling. 



On the 31st only one larva survived, having 

 apparently moulted for the third time. It was of a 

 pale drab brownish colour, with pale brownish 

 glittering head and plate ; the spots on the body, now 

 just visible, are about the same colour as the body, 

 but are shining, while the surrounding skin is dull. 



At this point the history of Lemiodes pulveralis 

 abruptly ends. There are various observations in my 

 Note Book down to pupation on the 16th October, 

 but I believe that a young changeling larva, unper- 

 ceived, was accidentally introduced, and devoured the 

 L. pulveralis, taking its place in my observations from 

 the 31st of August. 



On the 19th of July, 1881, Mr. Sydney Webb 

 kindly sent me another batch of eggs of L. pulveralis, 

 laid in a glass-topped box on the 16th by the parent 

 moth captured on the 14th. At 11.50 on the night of 

 the 26th they began to hatch to the number of five, 

 and these were placed on Mentha, hirsuta, potted for 

 them a week before. Next morning about thirty, 

 more or less, were hatched and placed on the leaves of
