112 ACENTROPUS NIVEUS. 



and in a day or two I found it bad spun itself up in 

 the axil of a stem of Pot. crispus and had drawn a 

 couple of leaves around it. The web was very white, 

 and on the day following I could see through the web 

 close to the stem-axil the head of the larva busily 

 spinning more silk from side to side at that part 

 within the cocoon. On the 28th I found the smaller 

 larva had also spun up between two leaves of Pot. 

 pertinatus, but only for moulting, and this was got 

 over by the 3rd of September, when it reappeared and 

 was feeding well and making many pellets of green 

 frass daily ; its situation when hidden from view 

 amongst the leaves of Pot. crispus could be readily 

 ascertained by the presence of a small air-bubble 

 floating near, and an air-bubble constantly floated in 

 attendance near by the cocoon ; and between the dates 

 of the 8th and 16th of September the moth — a 

 male specimen — was bred from it. On removing the 

 gauze cover to change the water in the pot on the 

 17th I found the moth floating near the side, and, of 

 course, dead ; and from my having neglected to pro- 

 vide a twig for the insect to ascend and develop its 

 wings, they were rather crippled, from its inability to 

 crawl up the slippery side of the pot. At the above 

 date the other larva was still feeding, as proved by 

 the little pellets of frass dropped at intervals in the 

 fresh water. (William Buckler, 17th September, 1881 ;

Hitherto the early stages of this species have re- 

 mained in profound obscurity, and now that I have 

 become familiar with them I can understand why the 

 larva, from its mode of life, had never been detected ; 

 therefore my pleasure is all the greater in being able 

 to render an account of it, which I owe to the discern-
