1 have only actually taken mysclt in Uniario. Dorcas I have from 

 Xepigon on Lake Superior, the Bruce Peninsula and from Manitoba, west 

 of that the form, for it is hardly a variety, yArz/j, which is really only a 

 dimorpiuc form of /lel/oiiffs, occurs, and has, I think, sometimes been 

 recorded as epixanthf. The reference of florus to dorcm instead of 

 helhidfs as a variety, which was done by Dr. Hynr, has, in my opinim, 

 no reason in it at all." 



This is a mistake. Florus does not belong to helloides ; it is simply 

 a form of dorcas, and occurs only in the female sex. Why Dr. Fletcher 

 should have been in doubt as to the identification of fpixanthe is not 

 clear, unless he failed to see all the specimens, {ox four were reported as 

 captured, and it would seem as thouj'h some one of them would have been 

 recognizable. 



Epixixntlie was located in Dickinson County in at least two places, 

 and possibly in a third. It was first found at Tomahawk Lake (1*1. V, figs. 



2 and 3), a small lake of about ten acres extent, just west of Hrown Lake. 

 Surrounding the lake was a typical black spruce and tamarack bog, from 

 which the higher vegetation was largely removed by the fierce forest fires 

 of the preccdint; season, which had left only a few trees and a margin of 

 uiiburnt vegetation a few feet to forty or fifty feel wide at the water's edge. 

 \\ iihin this area grew a variety of bog plants antl a goodly amount of 

 cranberry. 



F.pixauthe was first detected in this bog on July 9th. It was in its 

 prime from about the 1.1 th to the 17th, on each of which dates and on the 

 15th a fair number were observed flying. .Males were always more 

 numerous than females, in the proportion of four or five to one. The last 

 seen at Tomahawk Lake were on the 3oih, when three or four worn males 

 and one female were observed. On August iSth a belated female was 

 met with near Tamarack Lake, about two miles south of I'rown Lake. A 

 brief search resulted in the finding of some cranberry nearby. The third 

 instance in which the species was probably detected was on July 24th, 

 when a small bulteilly, which I toik to be e/>i.\ant/ie, was Unshed out, but 

 not captured, in a cedar tam.irack swamp not far from I'.rown Lake ; 

 cranberry was also growing there. 



The buttei flics of epi.xixnihe were very uniform, and differed from 

 specimens from other localities only in a slight difference in the colour of 

 the under surface. 'This was a purer, chalky white, esjiecially on the hind 

 wings, than in sj)ecimens from Ottawa, Canada, and I^ikewood, New 

 |cr>;(y. c\ani|)lcs from the last named place bcini; docideillv yellowish.
