CLEVELAND LEPIDOPTERA IN 1904. 



The weather prevailing during this year was a great improve- 

 ment on the past two or three years and much more likely to be 

 favourable for insect life, but notwithstanding the favourable 

 weather the macro ledidoptera were, if anything, even scarcer than 

 during the past years, this result no doubt being attributable in 

 a great measure to tbe cold, wet and sunless weather prevailing 

 during the past two or three summers having proved very 

 destructive to insect life in the earlier stages. Another factor 

 which probably militated to a great extent against " sugar " 

 which proved a total failure throughout the season, was the great 

 abundance of "honeydew" wbich prevailed as a result of the 

 fine, dry weathi r, which we had for the most part of the summer. 



Owing to the scarcity of the larger insects, I devoted my atten- 

 tion more to the micros than usual with the result that I have 

 been enabled to add a good many new species to our local list, 

 and one of which proves to be an addition to Mr. Porritt's list of 

 Yorkshire Lepidoptera. 



I am indebted to Mr. Jno. Gardner, of Hartlepool, and Mr. 

 Eustace Bankes. of Corfe Castle, for assistance in naming most 

 of the micros recorded below.
