BOTYS ASINALIS. 135 



pupae, with the antennae and wing-cases reaching far 

 down the abdomen, and ending in a projecting knob. 



On the 31st of August and two following days 

 there emerged five imagos, rather under-sized, but 

 very perfect; I suppose that in nature this species 

 cannot be double-brooded. 



Mr. Hudd has kindly supplied me with the following 

 dates of its appearance : 



This year he took the moths at the beginning of 

 July, and could see no more after the middle of the 

 month ; however, within the last day or two he has 

 found in his garden (on madder growing there) two 

 very young larvae, and the eggs whence these emerged 

 could not have been laid earlier than the 20th of 

 August ; in 1864 he took the moth on the 14th of 

 August ; and he tells me that he once knew it taken 

 at ivy so late as the end of September, but it was then 

 in a very worn condition. (John Hellins, 6th Sep- 

 tember, 1865 ; E.M.M., November, 1865, II, 135.) 



On the 11th of May, 1876, I received through the 

 kindness of Mr. A. E. Hudd, of Clifton, Bristol, half-a- 

 dozen larvae of this species. 



Two of them were full-grown, and were an inch 

 and an eighth in length ; the middle segments were 

 plump and round, but each becomes smaller than its 

 predecessor from the middle to the extremities, 

 giving the body a strongly attenuated appearance. 

 The head is broad when seen from above, but narrow 

 when viewed from the sides ; the lobes are rather 

 rounded and polished. The body is irregularly 

 cylindrical, each segment tapering towards its edges, 

 and thus rendering the divisions very conspicuous ; 

 each segment is also further divided into two parts 

 by a central transverse groove. The skin is soft and 

 semi-translucent, clothed with a few short hairs. 

 The last pair of prolegs is extended in a >-like form 

 beyond the anal segment. The ground-colour is dull 

 pinkish-brown, brighter in young specimens ; the 

 head is straw colour, marked with darker brown ; the
