MESOGONA ACETOSELL.E, Fab. 



The above figure represents a specimen of Mesogona ocetO' 

 sella taken at "sugar" by Mr. Thomas Salvage on the evening of 

 Saturday, 26th October last, in his garden at Arlington, Sussex, 

 and, so far as I am aware, it is the first recorded occurrence of 

 the species in Britain. 



In the earlier part of the present month I had an opportunity 

 of inspecting Mr. Salvage's captures of the present season, and 

 on looking through one of his boxes I detected an insect that 

 I could not identify with any of our British species, and which he 

 told me he had recently taken — in fact, had only removed it from 

 the setting-board that morning. He described its appearance at 

 the time of capture as resembling a strongly-marked Tceiiiocampa 

 stabills, but could not understand that species being on the win^^ 

 in the autumn. At my request he very kindly granted me the 

 loan of the specimen until the following day, and on my way 

 home, happening to meet my friend Mr. C. G. Barrett, I showed 

 it to him, and he at once recognized it as M. acetosellce. The 

 specimen is a female, and, with the exception of worn fringe, is 

 in fairly good condition, but from the appearance of the abdomen 

 had evidently parted with her ova before capture. 



On the European continent the species has a wide geographical 

 range, extending from Central Kussia, through Germany and 

 Switzerland to France, but is said to be somewhat local. The
