162 The Insects of Cambridgeshire 



Gamlingay; A. aglia, L. was common in Bottisham and the 

 adjacent fens, up to thirty years ago, and Melitaea <mrini>i, 

 Rott. also occurred in various parts of the fens, but has not 

 been recently recorded. Of the genus Vanessa, V. C-album, 

 L. was not uncommon at Shelford about 1840, and F. antiopa, 

 L. has been frequently taken in the county ; the remaining 

 species are all more or less common. 



Thecla w-album, Enoch, occurs at Madingley and other 

 localities in the west. Mr P. T. Gardner finds it plentiful, 

 sometimes abundant, at Conington; it is doubtful whether 

 any other species of this genus now occurs in the county. 

 Polyommatus dispar, Haw. had probably ceased to exist in 

 Cambridgeshire long before it finally disappeared from the 

 Huntingdonshire Fens, but Mr "Wagstaff took a specimen on 

 Bottisham Fen in 1851, the year Whittlesea Mere was 

 drained. 



Lycaena acis, Schiff., now extinct, occurred plentifully 

 around Cambridge up to fifty years ago; L. argiolus, L. 

 which was hardly known in the county previous to 1900, 

 turned up then in several localities near Cambridge, and it 

 has occurred regularly since, not only in and near the town, 

 but at Shelford and the Gogmagogs, and in the extreme 

 west of the county. The common Hesperidae, including 

 Hesperia comma, L., are all plentiful; Hesperia lineola, only 

 noticed as occurring in Britain ten or twelve years ago, is 

 common in Burwell and the adjacent Fens, also in the 

 extreme west, and in the south. 



HETEROCERA. 



Sphinges. 



With the HETEROCERA it becomes necessary, in order not 

 to exceed the space allotted to this article, to refer only to 

 species of exceptional local interest. 



Among the Spkingidae, all of which are plentiful, witli 

 the exception of the occasional migrants, Aclwrontia atropos,
