Probably it is well known to you that the Hepialid^ie are a very 

 interesting group of the Lepidoptera — from a scientific point of 

 view- — possessing as they do certain affinities with the 

 Trichoptera ; the Hepialida; are not without interest from the 

 economic point of view also. I shall however, deal with the 

 former, 



A note of the distribution, so far as is known to me, may be 

 of interest. In Europe there are eight representatives all of the 

 genus Hepialus, five of these are British. I have no list from 

 America, nor any means of reference, but am acquainted with 

 several species. I do not believe them numerous, as recently, 

 Professor Dyar stated that not sufficient material has yet been 

 studied for the modifications of larval structure to be known 

 (Ento Record IX-137). This would hardly be so if the group 

 had numerous representatives in America. From Africa I have 

 no lists, but there is a fair number of species, and in that 

 country the same development of antennal appendages takes 

 place — as in Australia — in the imagines. From Asia I have no 

 lists, and have no reason to believe the group numerous. I have 

 received one species from Ceylon, but there are more. It is in
