A form of great size, $ 9 often 2J inches in expanse ; the <^ is 

 sometimes partially suffused with orange, like Eurytheme, as in 

 the examples figured by Edwds., which were taken at Slave 

 River, B. C. Jn the examples from N. S. Wales, B. C., the 

 males are lemon yellow, like the typical Labrador form ; the 

 females are both yellow and white, the latter greatly in ex- 

 cess of the former. Above Lake Athabasca both the orange 

 and yellow $, and the yellow and white 9 forms occur. All 

 four exceed in size those from N. E. Labrador.
