 few additional species taken in Platte Canon, in July, 1878. 



LEPIDOPTERA RHOPALOCERA. 



PapUio ZolicaoH Bdl. A single specimen was taken in Platte Canon at an alti- 

 tude of 8,000 feet. 



Papilio Eurymedoa Bdl. Found in considerable numbers iit an elevation of 8,000 

 to 10,000 feet, about the summits of rocky peaks. 



Papilio Rutulus Bdl. Taken in open woods along the Ute Pass road — 7,000 to 9,000 

 feet. 



Papilio DaumiH Edwards. Not uncommon in Engelmann's Canon and other 

 canons, at an altitude of 6,000 to 8,000 feet. This species is very swift in flight, and 

 exceedingly difficult to capture. 



Paniassius Sviintliem Doub. Found at all elevations from 7,000 to 13,000 feet. 

 Specimens from above timber line on Pike's Peak, have the wings nearly trans- 

 parent. One or two examples of var. Belirii Edw., were captured on Pike's Peak. 



Pieris Protodice Bdl.-Lec. Common at Colorado Springs, in Engelmann's Canon, 

 and at other low elevations. 



Pieris oleracea Bdl. Only two or three specimens were seen — these being at an 

 elevation of 9,000 feet. 



Nathalis lole Boisd. Taken occasionally at low elevations. 



Colias Eurytheme Bdl. Taken at all elevations below 10,000 feet. Yar. Keewaydin 

 Edw , also occurred. 



Colias Meadii Edw. Abundant above timber line on Pike's Peak — altitude 13,000 

 feet. 



Colias Alexandra Edw. Taken idong the Upper Arkansas, also in Platte Carion, 

 near Dome Rock, at an altitude of 7,500 feet. 



Colias Philodicc Godart. Specimens of this species differ somewhat from the 

 Eastern form, and are considered by Mr. W. H. Edwards to constitute a distinct 

 species. 



Terms Mexicana Bdl. Taken in Jones's Park, along the Signal Service Trail to 

 Pike's Peak, also near Dome Rock in Platte Canon. 



Danais Archippus Fab. Found at all elevations up to timber line. 



Euptoieta Claudia Cramei'. Found abundantly at same elevations with the last 

 species. 



Argyanis Aphrodite Fab. var. Alcestia Edw. Common in Engelmann's Caiion, and 

 Platte Caflon, at middle elevations.

 sas valley. 



Argyn?iis Helena Edw. Found at high elevations, extending above the timber 

 line nearly to the summit of Pike's Peak, 14,000 feet above the sea. 



MeliUea nuhigena Behr. Taken at all elevations from 7,000 feet to timber line. I 

 am unable to detect any specific difference between this species and M. Anicia Doub. 



Melitoia Oabbii Behr. This species had not previously been taken in Colorado. 

 Only one specimen was secured — below timber line on Pike's Peak. 



Melitcea mmuta Edw. Not before taken in Colorado. Several specimens were 

 obtained by our party in the South Park.
