136 Tryon Reakirt on Coloradian Butterflies. 



Mr. Ridings informs me that this is common in the mountains, from 

 the beginning of July to the middle of August, having taken it all 

 the way from Golden Gate to Empire City : he observed that its flight 

 was straight forward, and not so much in starts as in the allied species, 

 settling but seldom. 



From the examination of a large number of specimens, I should 

 not be at all surprised if the 9 var. described by Mr. Edwards, 

 should prove to be the normal form, as I have not only found them to 

 be the most abundant, but also as in that case, it would be pursuing 

 but the usual analogous type of coloration, iu this instance peculiarly 

 generic. 

 Colias Scudderi, Reakirt. 



Sab. — Empire City, Colorado Territory. (Coll. Tryon Reakirt, and 

 Ent. Soc.) 

 Colias Eurytheme, Boisd. 



Hub. — Empire City, Colorado Territory; California (Coll. Tryon 

 Reakirt). 



Texas, California, Nebraska, Mississippi, (Coll. W. H. Edwards). 



" Mexico, California," (Rev. J. G. Morris). 



A species of wide distribution, as will be seen from the localities 

 given, and presenting little or no variation. 



Very common in August, over the plains, and through the moun- 

 tains ; flight very similar to Philodice ; the wild Sunflower (Ilelian- 

 thus, sp.) is a common food plant. 



On page 10, Appendix VIII, Cat. Brit. Mus. following Callidri/as 

 Gorgophone, is a Colias? from the Reeky Mountains, this may prob- 

 ably be referred to either Alexandra or Scudderi. 



Euptoieta Claudia, Cramer, sp. 



lhih. — Rocky Mts., Colorado Territory; Schooley's Mt., N. J.; 

 Philadelphia; Honduras. (Coll. Tryon Reakirt.) 



Also a species of wide geographical distribution, nearly constant in 

 all its area. 



It is very common in the mountains, and enclosed valleys; of very 

 quick, but not an high flight; is as partial to the Helianthi as the pro- 

 ceeding, and may be taken from June till August.
