C. Scudderi is known from Hudson's Bay, Lake Labache, 

 British Columbia and on the higher mountains of Colorado. 



C. Edwardsii from California, Oregon. Washington Territory, 

 Montana, Utah and Yellowstone. 



C. Alexandra from Kansas and Colorado, up to 11,000'. 



C. occidentalis from Washington Territory and Br. Columbia. 



C. Christina from Great Slave Lake and Athabaska. 



C. Harfordii from California, Washington Territory, Montana. 



C. Laurentina from Cape Breton, Nova Scotia and N. Maine. 



This species therefore goes through the whole continent from 

 the 45° to 55° ; in the Rocky Mountains it goes farther south to 

 Ft. Hays, Kansas, 2000'; in the north it goes perhaps mostly to 

 60°, and at least farther up to the Great Slave Lake. 



4. C. Palaeno. 



Yar. C. Pelidne, Boisd., Staudinger. 



C. Chippewa. 



If Scoresby's specimens belong here it reaches 70.30° on the 

 eastern coast of Greenland at the Scoresby's Sound. It is com- 

 mon in Labrador down to Caribou Island. Christoph quotes 

 Baring's Island 74° for C. Pelidne ; both forms are quoted from 

 Alaska, and C. Pelidne from Sitka and the Yukon River. 



C. Chippewa is quoted from the Mackenzie River and the 

 Great Slave Lake. The range of this species is from 54° to 64° 

 through the whole continent, with the exception of the two local- 

 ities quoted 70.30° and 74°. 



5. C. Meadii. 



Only on the higher mountains of Colorado. Strecker, N. A. 

 Macrol., p. 83, says : "So close to Hecla that I almost doubt its 

 being distinct." No C. Hecla is before me. Zeller after compar- 

 ing C. Meadii specimens determined by Mr. W. II. Edwards, and 

 communicated to him by the Museum, says, Stett. Ent. Zeit., Yol. 

 35, p. 437 : "The presence of the mealy spot just as in Myrmidone 

 makes the difference between both species somewhat doubtful. 

 I consider now only as a specific character the faint discal streak 

 of C. Meadii, instead of which C. Myrmidone has a considerable 

 spot. Should C. Meadii also appear with such a spot, which I 

 think to be very probable, I would recognize this species undoubt -
