Through the work too of Messrs. T. Ashton 

 LofthoLise, F. Elgee, W, Sachse, and others, we have 

 learned a good deal about the species occurring in Cleve- 

 land, an important area of our county, in which, except 

 in one or two localities, but little had been done 

 at the time of the publication of the former list. Mr. 

 B. Morley too, has done splendid work at Skelmanthorpe, 

 an outlying part of the Huddersfield district, but in many 

 respects different in character to the parts uf that district 

 which had for many years been worked so assiduously 

 and well. It is not surprising, therefore, that Mr. Morley 

 turned up a number of species which were rare, and some 

 which were altogether absent, even only several miles away, 

 notably Xanthia aurago and Eiiperia fiilvago, though as 

 the latter is evidently rapidly extending its range, it is likely 

 enough that it has only very recentl}- reached Skelman- 

 thorpe. 



The micro-lepidoptera have had two excellent workers in 

 the Rev. C. D. Ash and Mr. H. H. Corbett, but unfortu- 

 nately these gentlemen appear to be the only lepidopterists 

 who have done any systematic work in the group. They 

 have, however, had a good coadjutor in Mr. J. Sumner, 

 who, although not specially interested in micros himself, 

 took the trouble to set and get named such species as came 

 into his moth traps, and thereby did much valuable service. 

 By one or another, many old and single records have been 

 confirmed by captures in new localities ; but in the group 

 there is still very much to be done, and there is no doubt 

 whatever, that with more workers, many additional species 

 would still be added to our list ; and it is not too much to 

 expect they would include some new to Britain, and possibly 

 new to science.
