leaves coming out. The snow and ashes were removed from the top of 

 the box on ist May, and the box opened. The card pill-boxes were 

 found very damp and mouldy, but the two larvae; were sound and healthy 

 in spite of the mould all about them, but were naturally somewhat 

 shrunken in size from their long fast. 



At midday, on 3rd May, as I found that they had moved from their 

 positions, I placed them very carefully upon the open buds of a sprig of 

 Vaccinium, arranged in water as previously. They soon crawled on to the 

 stem and rested, one head down, the other up. 



During the 4th they remained lethargic, in the same position, but by 

 the morning of the 5th the one which previously had its head up had 

 turned round and had its head down, and by the evening I found that 

 they had eaten a little. They now eat the entire leaf, which is young and 

 tender. 



On 9th May they moulted for second time. 



After 2nd moult. — Length, about 7 mm. Head green, slightly 

 roughened with minute brown points. Body green, with many minute 

 yellowish raised spots, each lipped with a minute brown hair or point. 

 Along the spiracular space there is a raised band like a fold, mottled with 

 white, pink and yellowish. 



On 1 2th May one passed 3rd moult about 3.30 p.m. while under 

 observation. When first seen the old face still adhered to the mouth- 

 parts of the new, but the skin had been worked more than half way to the 

 anal extremity. It only took a very few minutes to get clear of the old 

 skin, and then it proceeded to divest itself of the old face, which it soon 

 accomplished. 



After 3rd moult. — Length at rest, 8.6 mm. Head bright green, 

 roughened as before. Body darker green, shagreened with yellowish 

 raised spots, with short brown hairs or points. Spiracular fold as before, 

 whitish, with orange and yellowish patches and markings. 



The weather turned cold and wet, and the second larva was two or 

 three days later in moulting than the other, but the exact date was not 

 recorded. 



The species of Vaccinium that Mr. Fletcher supplied me with was 

 Canadense, but I had also received V. Vacillans from Mr. Jack. On the 

 17th a careless servant threw away my supply of V. Canadense, so I gave 

 the larv?e the V. Vacillans, but the following day I found they had "fefused 

 jt and had eaten nothing, so I offered them some of the sprigs that I had
