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 ciliae ; each has a black spot on 

 its outer side. This larva was found in Alderney, feeding on 

 the leaves of the large bindweed, Convolvulus sepiura. The 

 specimen buried itself on the 14th of October, and so remains. 

 1 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 maxillae is trans- 

 versely marked, as if with rings ; it is 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, Hylhe, Kingsbury, and a variety of other 

 places in the vicinity of London, Leytou, 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
