AUGUST. 143 



while on the hill, in the centre of the pit, the larvae 

 of Arctia villica may be obtained plentifully in the 

 spring months by raking them out from the roots 

 of the Hieracium ; while the hanging wood contains 

 many fine old trees, together with a good undergrowth. 

 Here the beautiful Cocky lis dipoltana was first taken, 

 and here too Gelechia acuminatella occurs, together 

 with Depressaria nanatella and Parasia Metzne- 

 riella, while among broom we shall find Trifurcula 

 immundella and T. squamatella. 



Among grass we shall find Elacltista Megerlella 

 and E. obscurella — while among the common reed 

 (Antndo phragmites) in the Greenwich marshes Ela- 

 chista cerusella occurs, together with its larvae mining 

 in its leaves. 



But to leave Charlton and its Sand Pit, and to dis- 

 course of the species generally to be found this month. 



Among Atriplex, Coleophora annulatella occurs ; 

 while among Helianthemum vidgare we shall find 

 Ltrcerna Staintoni; and among Epilobium hirsutum, 

 Laverna Epilobiella and Anybia langiella occur. 



In the leaves of willows, sallows and poplars, roll- 

 ing the leaves into cones, we shall find the larvae of 

 Gracilaria stigmatella; while in rolled-up leaves of 

 alders the larvae of Gracilaria elongella occur, together 

 with the larvae of Pklfeodes frutetana, and the dark- 

 coloured and sluggish larvae of Ypsipetes impluviaria; 

 it is desirable to keep the larvae of Y. impluviaria by 

 themselves, as, should the vegetable pabulum become 

 distasteful to them, they make no ceremony in appro- 

 priating the Gracilaria larvae to the purposes of nutri- 

 tion.
