Local : 1 ^ Spridlington, Lincolnshire ( WoUaston) ; 1 ^J from 

 Mr. Or. E-. Crotch's collection, without note of locality ; $ taken 

 in some number by Dr. Power, in June, under leaves on a hedge- 

 bank, at Highgate Wood ; afterwards ^ and ? taken by us at the 

 same place, several pairs being seen in cop., thus confirming the 

 observations, as to the sexes, of Herr Tieffenbach (' Berl. Ent. Zeits.' 

 1861). In Germany the species is found in the nests of ants; but 

 in our experience, although there were ants on the bank, the 

 Myrmedobia were not associated with them. The ^ is extremely 

 active, and instantly takes flight ; the ? , at first sight, is very like the 

 coleopterous Alexia pilifera, which was found with it.
