NOTES AND OBSERVATIONS. 



LiNNEAN Society's Gold Medal. — Entomologists will congratu- 

 late warmly Dr. F. DuCane Godman, F.R.S., the recipient this year 

 of the Linnean Society's gold medal. The award is made in recog- 

 nition of Dr. Godman's monumental contribution to science, the 

 ■' Biologia Central! Americana,' conceived many years ago by himself 

 and the late Mr. Osbert Salvin, F.R.S., covering all branches of 

 the Central American fauna, including Lepidoptera and Arach- 

 nida, as well as the regional flora, to which alone five volumes are 

 devoted. Mr. Salvin died in 1898. Happily, Mr. Godman has sur- 

 vived to see the completion of his magnificent work. Honour to 

 whom honour is due. 



Celastrina argiolus in London. — While walking in Piccadilly 

 this morning at 12.45 I saw C. argiolus flying over the tall iron rails 

 in front of Lord Rothschild's house. — G. 0. Sloper ; Badminton 

 Club, 100, Piccadilly, W. 1, May 19th, 1918. 



NoMiADEs semiargus IN BERKSHIRE. — You may be glad to hear of 

 a capture which has just come to my knowledge. Mr. L. Matthews, 

 an enthusiastic young collector, recently asked me to confirm his 

 identification of a butterfly taken by a friend of his in July 1908. 

 This proved to be a male of Nomiades semiargus (acis), and the locality 

 given is Mortimer, near Reading. I have shown this butterfly to 

 Mr. A. E. Hudd, who took six examples in South Wales in 1871. 

 Barrett speaks of these as captured at Llantrissant, but Mr. Hudd 

 tells me that two only were taken at that place, and four near Penarth. 

 He also recalls, what I had previously heard from the late Mr. J. W. 

 Clarke, that on one occasion, when the Bristol entomologists visited 

 Llantrissant, Mr. Evan John had the edges of one of his fields mown 

 so that they might have a better chance. Now that this new record 

 brings the capture of British species up to ten years ago only, it seems 

 quite possible that a small number of semiargus may still survive in 

 this country. — George C. Griffiths ; Penhurst, 3, Leigh Road, 

 Clifton, Bristol. 



[Mr. Griffiths has kindly given me permission to pubhsh the 

 above notice in the ' Entomologist.' There is a passage in Mr. 

 Hudd's interesting reminiscence of the visit to Mr. Evan John's 

 fields, which conceivably explains the disappearance of the butterfly 

 from that particular locality. It is possible that, by clearing the field 

 edges, Mr. Evan John actually destroyed the larvae or pupae of the 

 " Mazarine Blue." I think Dr. Chapman has suggested that the dis-
