170 TJie Insects of Cambridgeshire 



noteworthy is Argyrolepia schreberiana, Frol., which \\.-is 

 plentiful near Ely station fifteen years ago, but has not been 

 found for some years. 



Among this, the last and most numerous family of Lepi- 

 doptera, we find a considerable number of species, especially 

 among the Gelechiidae, which are exclusively Fen-dwellers. 

 Dasystoma salicella, Hb., which generally occurs sparingly in 

 hawthorn hedges, the writer once saw flying in large numbers 

 on Hills Road. Tinea pallescentella, Sta., at one time con- 

 sidered a scarce insect, is very plentiful in some Cambridge 

 houses. Micropteryx calthella, L. is common throughout the 

 Fens, and M. thunbergella, Fb., at Chippenham. NemopJiora 

 metaxella, Hb., a very local species, is plentiful in the Fens. 



The beautiful species of Adelidae, Adela croesella, Scop., 

 and A. degeerella, L., occur at Chippenham, Nematois cupria- 

 cellus, Hb., occasionally at Fulbourn and other localities, and 

 JW. fasciellus, Fb., sometimes in fair numbers at Burwell. The 

 two local and pretty species Anesychia Junerella, Fb., and A. 

 decemguttella, Hb., are found commonly in the Fens, the former 

 in Wicken and surrounding Fens, the latter at Chippenham. 

 The genus Depressaria is well represented, especially in the 

 Fens; the most noteworthy species are D. costosa, Haw., D. 

 flavella, Hb., D. pallor ella, Zell., -D. umbellana, St., the w/r. 

 rhodocrella, H.-S. of D. subpropinquella, Sta., D. purpurea, 

 Haw., D. liturella, Hb., D. co?iterminella, Zel., D. angelicella, 

 Hb., D. yeatiana, Fb., D. ciliella, Sta., and D. chaerophylli, 

 Zell. Among the remaining genera of the Gelechiidae are to 

 be found the greatest number of purely fen species of all the 

 Lepidoptera with the exception perhaps of the Leucaniidae. 

 Of these mention may be made of Gelechia muscosella, Zell., 

 G. divisella, Doug., and G. rhombella, Schiff. ; Brachmia 

 lathyrella, Sta. ; Bryotropha umbrosella, Zell., and B. basalti-
