274 THE ENTOMOLOGIST. 
spiracle forms the centre of a nearly circular black spot; the 
nine spiracles thus surrounded form the third spiracular 
series ; the medio-ventral line, already described, is dilated into 
a black blotch between each pair of abdominal claspers; the 
legs are black and shining: the claspers are pale green, with 
black, curved and prehensile ciliz ; each has a black spot on 
its outer side, This larva was found in Alderney, feeding on 
the leaves of the large bindweed, Convolvulus sepium. The 
specimen buried itself on the 14th of October, and so remains. 
I will now say a few words about a pupa of the same species, 
dug up in a potato-field at Deptford, and now before me. 
This is two inches and an eighth in length, and of propor- 
tionate thickness: the case containing the maxille is trans- 
versely marked, as if with rings; itis perfectly detached from 
the body, except at its insertion; it is parallel with the body 
for two-thirds of its length, and then, after nearly touching 
the leg-cases, is bent inwards and upwards, and terminates in 
a blunt extremity ; the anal extremity of the pupa is obtuse 
and scabrous. 
The extraordinary abundance in which this species has 
appeared this year, as recorded in the pages of the ‘ Ento- 
mologist, is only equalled by the records in the ‘ Zoologist’ 
for 1846, when it appeared throughout the length and 
breadth of the kingdom. Taking the records alphabetically, we 
find it occurred at Aylsham, Blackheath, Bridlington, Cam- 
berwell, Carlisle, Chipping Norton, Chelmsford, Clonmel, 
Dunmow, Faversham, Hackney, Hessle-on-Humber, Hull, 
Huddersfield, Hythe, Kingsbury, and a variety of other 
places in the vicinity of London, Leyton, Leicester, Norwich, 
Nottingham, Preston, Reading, Sudbury, Tooting, Tunbridge, 
Uppingham, Winchester, York, and Yarmouth: in the last- 
named locality it is reported to have occurred “in immense 
quantities,” one person having taken fifty-seven, and enormous 
numbers having been seen on Caistor Marrams, a sandy 
district by the sea-shore. The interval of twenty-nine years, 
between 1846 and 1875, did not pass without the occurrence of 
Convolvuli being occasionally noticed ; and I find captures of 
the insect recorded in almost every volume of the ‘ Zoologist’ 
or ‘Entomologist’ until this year. In 1868 it appeared in 
abundance on the Norfolk and Suffolk coast, more particu- 
larly at Aldeburgh, as recorded in the ‘ Field’ newspaper. Its
