LOBOPHORA VIRETATA. 57 



the cage to itself, introducing no other larvae, but one 

 day, about the middle of August, he looked into it to 

 see that all was right, when he was astonished to 

 discover two perfect specimens of Lobophora viretata 

 evidently just out, and a day or two afterwards to 

 find a third specimen, and thus became aware of the 

 identity of the little larvae he had been previously 

 throwing away. With both of us, therefore, Lobophora 

 viretata proved double-brooded in confinement ; that 

 it is double-brooded also in nature I obtained evidence 

 on the 8th of September, 1875, when a friend, who 

 was with me helping to search for larvae of Lycxna 

 argiolus, found a very different larva sitting in the 

 midst of a small umbel of blossom-buds of Hedera 

 helix, which was surrounded with a very thin and 

 transparent open-meshed web ; several of the buds 

 were eaten out and a few grains of frass were clinging 

 to part of the web. I felt a little puzzled for a few 

 hours about this larva, which then had no marking, 

 and was like the ivy-buds in colour when first found; 

 but a subsequent examination convinced me that it 

 was Lobophora viretata; it moulted on the 13th, and 

 continued to feed well on ivy-buds until the 21st of 

 September, when it burrowed into the earth, and the 

 moth, a fine male, appeared early in the morning and 

 was flying round its cage in the afternoon of the 6th 

 of May, 1876. 



The full-grown larva is about half an inch in 

 length, or a trifle more when stretched out, thick and 

 stumpy in aspect, the head fitting partly within the 

 second segment, which is smaller than the third and 

 fourth, they being tumid both above and at the sides ; 

 the last two segments a little taper to the end, which 

 has two minute anal points ; all the segments are 

 plump, yet having two or three transverse wrinkles at 

 each end, though not very noticeable till the larva is 

 full-fed ; the minute tubercles are warty ; when the 

 larva is at rest, and often while feeding, the head is 

 tucked under the thoracic segments, which are arched
