his experiments. Of M. Oberthiir's descriptions, with the 

 exquisite ilhistrations attached, we can only add that they bring 

 to bear upon the facts corroborative evidence of the highest im- 

 portance. Many of us during our wanderings abroad have col- 

 lected ample material to test for ourselves the accuracy, if not the 

 finality, of these respective conclusions. Our cabinets and store- 

 boxes teem with unnamed or wrongly-named Hesperiidse, whose 

 proper identification we have either shirked altogether, or given 

 up as a hopeless task with the text-books at our disposal. In 

 the long winter evenings, furnished with this new information, 

 we may hope to reduce chaos to order before once more betaking 

 ourselves to the mountains and flowery lowlands which are our 

 own particular happy hunting-grounds across the Channel.
