N0.14S8. BUTTERFLIES OF BRITISH AMERICA— GARY. 437 



and a marked geographical variation was also exhibited, males from 

 Lake Athabaska being much more heavil}' suffused with orange than 

 Hudson Bay specimens. Doctor Fletcher records two examples which 

 Frederick Bell collected at Fort Simpson — a male, July IT, and a female, 

 July 25, 1SS8; and also lists the species from Fort Good Hope, where 

 William Ogilvie secured it August [July?] 11 of the same 5^ear." 

 E. christhui has its center of al)undance in the Saskatchewan region. 



EURYMUS PALAENO (Linnaeus). 



This species occurs in small luunbers from Fort Providence north- 

 ward, and is usually seen in grass\^ muskegs. 1 collected six speci- 

 mens in 1903, as follows: Fort Providence, July 8, four; Nahanni 

 Mountains, July 10, two. Mr. Preble did not meet with this butter- 

 tly on the lower Mackenzie Kiver in 1904. 



White records specimens secured b}^ llichardson at Fort Simpson 

 in 1848.* Edwards based his description of Coliax Iwlcna {=p(daeno 

 Linnanis) upon specimens "from Mackenzie's River, taken by Mrs. 

 Koss."'' Doctor Strecker mentions 25 specimens of E. palaeno in the 

 collection he received from Geffcken.'' Jt is probable that some of 

 the latter were taken within Athabaska district. 



EURYMUS ALEXANDRA var. EMILIA (Edwards). 



I found this large, handsome Eurytnus in small numbers at Fort 

 Providence early in July, 1903, and also saw one or two near the 

 mouth of the North Nahanni River a week or so later. Two males 

 taken at Fort Providence, July 8, were in excellent condition. This 

 l)utterliy was observed only in grassy muskegs. 



E. emllia is a western form, and has not been previously recorded 

 from the north. 



EURYMUS NASTES (Boisduval). 



Elwes records four males and two females from the Barren Grounds, 

 140- W., 67 40' N.' These specimens were taken l^y the Hanbury 

 expedition in 1902. Francis A. Heron, of the British Museum, has 

 kindly gone over these specimens for me, and refers them to the 

 variety known as rossii Guenee. 



E. nastt-s is another Arctic species which could not be expected to 

 occur in the forested regions west of Great Bear and Great Slave lakes.
