47. Addendum to Mr. Bird's communication at p. 39. — Sir, In 



looking at my contribution to the volume of the Entomological 



Magazine completed with the present number, poor as the 



contribution is, it may be worth while to correct what is wrong, 



and to add something to it. — P. 42, line 1. " Those which 



I do not take by the lamp." I intended to limit this to the 



class, LejjidojJtera. — P. 43. In the list of Coleoptera, Callistus 



lunatus should be omitted ; I take it at Caversham, seven miles 



off, on chalk. In the list oi Diptera, I ought to have inserted 



Chironomus cestivus. $ During the present year, I have added 



to the Burghfield insects Tipula nigra? Notodonta perfusca, 



Clostera reclusa, Sesia Bombyliformis, and Nonagria crassi- 



cornis. I have taken a few specimens of Grammesia bilinea, 



Argyrolepia Turionella and Sargus Reaumuri. Cynthia 



Cardui has been very common here. We have seen a few 



specimens of Colias Electra.,

 convolvulus about the middle of the ninth month (September),

 Celerio was taken on a heap of stones early in the tenth month 

 (October), and brought to me alive. Four specimens of Colias 

 Hyale have been taken here this autumn by different col- 

 lectors.
