tion eiscwhere {antea, p. 17), 1 am inclined to believe that 

 the occurrence of this Butterfly in the Midland Counties is 

 less improbable than Mr. Barrett thinks. The form which is 

 found in the Canaries, and which has been supposed to be 

 identical with this, is now considered by Dr. Rebel to be a 

 distinct species, which he calls Thymelicus chrlsti. 



GENUS ERYNNIS. 

 Erynnis, Schrank, Fauna Boica, ii. (i) p. i57 (1801); Watson, 

 Proc. Zool. Soc. Lond. 1893, p. 99. 

 This genus and Aiigiades include larger species than Ado- 

 pcea, and the fore-wings are longer and more pointed, while the 

 bar of raised black scales on the fore-wings of the male is much 

 more conspicuous and strongly developed. The antennae are 

 hooked at the tips in both genera. There is but one European 

 species each of Erynnis and Aiigiades, both of which occur in 

 Britain. The present genus may be distinguished at once by 

 the distinct white spots on the under side of the hind-wings.
