TERIAS MEXICANA BDV. IN NORTHERN COLORADO. While mounting 

 some Lepidoptera collected by Mr. G. M. Kite and myself in the north- 

 ern part of Boulder County, Colorado, I came across three specimens of 

 Terias mexicana Bdv. They were collected by Mr. Hite in Copeland 

 Park, on the North St. Vrain Creek, September 6, 1907. Copeland Park 

 is in the lower part of the Hudsonian Life Zone, and has the altitude of 

 about 10,300 feet. 



The specimens agree in every detail with the figure of this species in 

 Wright's Butterflies of the West Coast, except that the secondaries in 

 one specimen are a trifle yellower. They are all males. The wings are 

 somewhat broken on the outer margin as if they had flown a long 

 distance. 



Mr. W. G. Wright (Butterflies of the West Coast) says that, as far as he 

 knows, T. mexicana has been found no place north of the Mexican bor- 

 der except in Arizona. Dr. Holland (Butterfly Book) says it is common 

 in Arizona and very abundant in Mexico. Dr. H. G. Dyar (Bui. 52, U. 

 S. Nat. Mus.), gives it from the Mississippi Valley and Mexico. Dr. 

 Skinner (Cat. N. Am. Rhopalocera)* gives it from Mexico, and Missis- 

 sippi and Colorado occasionally. Prof. T. D. A. Cockerell says it is 

 somewhat common in New Mexico and that he has seen it at high alti- 

 tudes. These localities have been given for New Mexico, Water Canon 

 (Snow), Mesilla Valley (Ckll.), La Cueva (Townsend), Pecos (Ckll.), 

 and top of Las Vegas Range, 11,000 feet. (Ckll. Psyche, Nov., 1901, 

 p. 272). Prof. D. T. A. Cockerell made this note in the Univ. of Colo. 

 Card Catalogue: "Terias mexicana Bdv. (1836). This is not in Gil- 

 lette's Colo, list, but I saw a light yellow Terias in Boulder Canon, 7,340 

 feet, September 22, 1907. It could not have been anything else." From 

 these two records from Boulder Co., in 1907, we may assume that a 

 goodly number of this species migrated northward along the eastern 

 foothill region of the Rocky Mts., or that they have come westward from 

 the Mississippi Valley. To me the first seem more probable. At any 

 rate the finding of this Sonoran butterfly in boreal, northern Colorado is 

 a matter of no little interest. S. A. ROHMER, Boulder, Colo. 



THECLA LOKI, SKINNER. This new species was discovered by me and 

 a party of enthusiastic collectors July 5th, 1906, on the road between 

 Jacumba and Mountain Springs, about 80 miles east of San Diego. 

 The country about is practically a desert. The vegetation is composed 

 of the common greasewood and cactus, with a little bunch of grass 

 scattered about. There is also quite a growth of Juniper on the hills, 

 and it is here that loki is to be found. He is a shy bird and keeps well 

 to the tops of the bushes; he is swift of flight, too. and owing to the 

 similarity of his color to that of the Juniper, cnnvspcmdingly hard to 

 take. At the time we were there it was probably late, as we only
