 Island, 1 9 . 



The only macropterous individual is a female from Alright 

 Island, in which the tegmina extend slightly beyond the apices of 

 the hind femora. In the other specimens from the Magdalen 

 Islands the tegmina reach about the end of the abdomen in the 

 males and in one of the females; in the others they are somewhat 

 shorter. The specimens from this group of islands are large, and 

 are, for the most part, dark and heavily banded. Six characteristic 

 specimens (3 cf , 3 9 ) from Alright Island measure as follows: —

The female from Grosse Island bears a marked resemblance to 

 M. altitiidinum in the large size, nearly uniform speckling of the 

 tegmina and broken piceous band on the lateral lobes of the pro- 

 notum.

The specimens from the Magdalen Islands are remarkable for 

 their extremely large size, while those from Bic and Prince Edward 

 Island are rather small.
