111 tlie Entomologists MdiithJij M((/ja:iliLc for 1887, Mr. E. 

 Meyrick recorded a specimen taken on September 1 of that 

 year in the mountains above Tenrhyn slate quarries, about 

 seven miles from Bangor. Although the sun was shining the 

 butterfly was sluggish and was easily caught. It was unknown 

 to the captor, a boy at Marlborough College, and was named 

 for him on his return to school. 



These two species of Parnassius are well-known inhabitants 

 of the Alps and Pyrenees, genuine mountain insects, extremely 

 local and sluggish, and by no means likely to migrate. 



Supposing there to be no cause for suspicion in the cases of 

 these two very circumstantial records, it can only be supposed 

 that the insects had been accidentally conveyed in the larva 

 or pupa state from their Continental homes among plants, 

 which, as is well known, are constantly forwarded in large 

 quantities to this country by tourists, for cultivation in 

 Alpineries. There is not a shadow of reason to suppose them 

 native, or that they would establish themselves with us.] 



[Thais rumina, Z.— A highly ornamental species- 

 yellow, with numerous black bauds and marginal crescents, 

 and some carmine spots scattered over the wings. 



In the Entovwlogists' Monthly Magazine for 1877, Mr. 

 Herbert Goss recorded the capture of a specimen in the 

 market at Brighton, but himself supplied its probable origin 

 from a pupa imported with fruit from the Medicerranean.]
