that Armathwaite has always yielded the larvse of this insect, as 

 I found many delicate tubes amongst the grey lichen on the 

 rocks, tenanted by light green larvae with black heads. As I 

 cannot find anywhere a description of the larva of this species, 

 this must be considered a mere conjecture, hazarded with the 

 view of extracting information from anyone who may know. 

 Elachista huniiliella. — This insect puzzles me. Can it be 

 the male of Elachista perplexella '} The ' Manual ' says of it, 

 "male unknown." Now in Brockholes Wood, near Preston, I 

 take yellow larvae feeding in Aira ccespitosa, which produce both 

 the dark males and the females with more distinct spots ; and 

 these, I venture to say, are probably respectively E. humiliella and 

 E. perplexella, thus reducing the two species into one, whichever 

 name may have the priority. Mr. Murray, of Carnforth, was last 

 year most fortunate in his captures at Witherslack amongst the 

 Micros. He took, and kindly gave to me, a male of Psyche 

 opacella and one of P. calvella, and it will be curious if we cannot 

 this year turn up these insects again. — J. H. Threlfall ;

Hymenoptera in Dorsetshire. — While searching for spiders 

 among heather, coarse herbage and debris, I have on various 

 occasions met with the following, mostly apterous, Hyme- 

 noptera. I am indebted for the names of these little insects to 

 Dr. Capron, of Shere, near Guildford, and Mr. Bridgman, of 

 Norwich, who have kindly examined the specimens. Pezomachus 

 micrurus, Foerst., appears to be new to Britain. I should add 

 that one of the examples of Hemimachus fasciatus, Fabr., male, 

 was bred from the egg-sac of a species of Theridion. Methoca
