WHAT HAS BECOME OF THE BEITISH SATYEIDiE ? 



By Prof. E. Meldola, D.Sc, F.E.S., F.E.S., &c. 



Among the reminiscences of my early collecting days some 

 forty odd years ago is the abundance of certain species of Satyrid 

 butterflies in the London district in localities from which they 

 have now disappeared altogether, or have become so scarce as 

 to appear notable when observed. It is not altogether a case of

 some wider cause than the spread of cities must be sought for. 

 It is noteworthy that the Satyridse should apparently be so 

 especially affected by adverse conditions. Let me, in the first
