NOTES AND OBSERVATIONS. 



Darwin Medal of the Eoyal Society. — Our readers will be 

 interested to know that this year the " Darwin Medal " of the 

 Royal Society is presented to Mr. Roland Trimen, M.A., F.R.S., 

 F.E.S., in recognition of the services rendered by him to entomo- 

 logical science, especially in connection with the work of the author 

 of the ' Origin of Species.' As Mr. Trimen's labours have been concen- 

 trated almost wholly upon Lepidoptera, the honour besto\yed upon 

 him will be generally appreciated by Lepidopterists throughout the 

 United Kingdom. It may be observed, also, that the Entomological 

 Society of London, at their meeting on November 16th, unanimously 

 approved the despatch of a letter of congratulation to the recipient 

 of what is regarded as one of the highest distinctions in the gift of 

 the Royal Society. — H. R.-B. 



Entomological Society of London. — Mr. H. Rowland-Brown 

 asks us to state that he will not seek re-election as one of the 

 Honorary Secretaries of the Entomological Society of London at the 

 Annual General Meeting to be held on January 18th, 1911. His 

 successor-designate is the Rev. George Wheeler, M.A., known to 

 many of us as the author of that very useful handbook ' The Butter- 

 flies of Switzerland and the Alps of Central Europe,' and a valued 

 contributor to the pages of the ' Entomologist ' as a high authority on 

 the western palaearctic Melitaeids. 



Further Notes Regarding the Breeding of Chilosia 

 GROSSA. — In my note on the breeding of this dipteron, in the 

 ' Entomologist ' for November, line 3, p. 314, should read : " They 

 pupate in the hollow stem." But from my experience of this year it 

 appears that this is not invariably, or perhaps even generally, the 

 case. I found in August last a patch of Cniciis palustris, in which 

 were larvae of Chilosia grossa in some numbers. I took only about 

 half-a-dozen, intending to take the pupas later on in the hope of 

 breeding more specimens of the ichneumon for Mr. Morley. To-day, 

 November 5th, I visited the place, but only succeeded in finding one 

 pupa, though the working of the larvae was apparent in many of 

 the thistle stems. Most of the stems which had contained larvae
