A New Variety of Chionobas. 



By Henry Skinner, M.D,, Philadelphia, Pa. 

 Chionobas alberta oslari n. var. 



Male expands 41 mm. and the female 45 mm. 



Male. — Primaries : Upperside smoky brown with a wide reddish 

 brown band crossing the wing from near the costa to the inner margin, 

 broken into quadrate spots by the nervures. On the first and third 

 of these are distinct black spots or points and sometimes a faint black 

 point on the central quadrate spot. 



Primaries. — Underside yellowish brown with the upper and lower 

 black point repeated ; a black line extends from the costa to the inner 

 margin, running parallel to the end of the discoidal cell, then bends 

 inwardly to the lower point of the cell and thence to the inner margin. 

 The outer end of the cell is black. 



Secondaries. — Above smoky brown with margins edged with fuscous 

 and a distinct black spot near anal angle. Below marbled with black 

 and white with two black parallel stripes or lines crossing the wing from 

 the costa to the inner margin ; they commence near the middle of the 

 costa about 5 mm. apart. The females are similar in markings to the 

 males. 



This variety is larger than any alberta I have seen. In color 

 and markings on the upper side it very much resembles C. 

 katalidin. On the under side it is the exact counterpart of C. 

 alberta. It probably expresses the relationship between a 

 mountain and a plains form. Described from two males and 

 two females taken by E. J. Oslar in Deer Creek Canyon, Colo- 

 rado, September 25, 1909. Types in collection of the Acad- 

 emy of Natural Sciences of Philadelphia. 



CoLiAS BEHRi. — From observations which I made, I am inclined to 

 believe that the natural haunts of these Alpine insects is in the high 

 Southern Sierras and that * * * ]\It. Lyell (Middle Sierras) is prac- 

 tically their northern range. They are not uncommon at altitudes 

 above 10,500 feet in the Southern Sierras (you can almost say that 

 you have reached this altitude by the abruptness with which they com- 

 mence there) and may be seen on pleasant days — the usual thing 

 there — in early July, flitting from place to place along the meadow-like 

 margins of the Alpine streams and lakes (no true meadows are there 

 — it has too recently recovered itself from the ice cap). I neglected to 

 trace a female to find the food plant, but believe that it must be a spe- 

 cies of alpine lupine, as that was the only leguminous plant there and 

 it was quite abundant. — Edwin C. VanDyke, San Francisco, Cali- 

 fornia.
