46 DK. BEACKENKIDGE CLEMENS' LETTERS. 



The number of workers at Micro-larvae in Europe has much 

 increased of late years, and I hope soon to have active correspon- 

 dents in the south of France and at Vienna, from both which 

 localities there is doubtless yet a good crop of observations to be 

 expected. 



In Italy I fear it will be some time before we see a native Micro- 

 Lepidopterist. Entomologists are far from numerous in Italy, and 

 I do not know of a single first-rate collection of Macro-Lepidoptera 

 there. 



I observe you are in correspondence with Mr. B. Walsh of 

 Rock Island. I had heard of him from Dr. Hagen, the great 

 Neuropterist, who seems to have a very high opinion of him, and 

 he had recommended me to write to him on the subject of N. A. 

 Micro-Lepidoptera. This I now see will not be necessary on my 

 part as he is already in correspondence with you, and I would 

 rather not attempt to divert the current of American captures, 

 but let them all pass, in the first instance, through your hands.
