It has also been reported from Arctic America' (Walker); Great 

 Bear Lake' (Scudder); Labrador' (Packard); Canada (Bethune, Caul, 

 field, Fletcher) ; Quebec (Provancher) ; Mount Ktaadu, ]Maine( Packard); 

 New Jersey (Smith); Pennsylvania (De Geer); Ohio and West Vir- 

 ginia (Glover) ; Kentucky (Glover, Garmau ) ; Tennessee (De Haan), and 

 Wyoming (Thomas). Si)ecimens from Florida which I formerly referred 

 to this species probably belong to the next. 



It t)ierefore appears to inhabit the entire United States and tht set- 

 tled parts of Canada, excepting only Alaska and also the southeastern 

 United States (where it is replaced by the next species), and occurs 

 south of our border as far as central Mexico. 



The species described by me as M. interior vf an, based upon specimens 

 from Utah and other parts of the interior of the western country, which 

 seem to differ from those found elsewhere in having cerci which taper 

 more gradually and show less contrast in the width of the basal and 

 apical halves, and at tip are blunter and less manifestly truncate, in 

 which also tlie forks of the furcula are relatively longer and more 

 strictly parallel, the tegmina rather shorter and generally lacking any 

 maculatiou v tmte\er; the prosternal spine also is more frequently com- 

 pressed before the tumid tip; but on comparing a large series of speci- 

 mens from these western regions I tind it impossible to draw any line 

 of demarcation, some specimens having some but not other of these 

 characteristics, so that I can only regard the species as in a state of 

 tiux in this region, preparing, as it were, to divide into distinct races 

 not yet clearly enough defined to distinguish them. 



' The first three references are doubtful ; they probaMy belong to M. extremum.
