GENUS LYCi^NA 217 



352. Chysophanus Rubidus. 



Plate XXVIII ; Figures 352, b, g. 

 Fig. 352, Male, no data. 



b, Female, no data. 



c, Female, underside, no data. 



The male on upper side is very like Cupreus, though larger, and 

 the female is darker than the female of Cupreus, a peculiar white- 

 and-dusky color, without much red or yellow. It is set down in 

 the books as living in Oregon, Nevada and Montana, but all I can 

 say about that is that I have not ever seen one in any one of those 

 States. 



353. Chrysophanus Sirius. 



Plate XXVIII ; Figures 353, b. 

 Fig. 353, Male, from Western Colorado ; D. Bruce, 

 b. Female, from Western Colorado ; D. Bruce. 

 Sirius is said to inhabit some of the States of the Great Basin, 

 from Arizona to British America ; it ought to be found in Eastern 

 Oregon and Washington, east of the Cascades, but I have not 

 heard of any such habitat having been established. 



Genus LYCffiNA. 



A large genus, of world-wide distribution. "The Blues" are 

 everywhere, in the springtime, on plain and on mountain aHke, for 

 generally these little butterflies are in flight in the spring only, 

 although several are summer and autumn-flying species, so that 

 we have them with us at all times except during the cold months. 



All Lycsenas have the peculiar habit when at rest or when feed- 

 ing on flowers, of rubbing their wings up and down with a gen- 

 tle motion, which reminds us of the way flies have of rubbing their 

 feet together; the wings do not touch together, nor do they rub 

 against anything else, and it is unknown what the object of the 

 motion may be. If from any cause the butterfly becomes disturbed, 

 it at once stops the motion until the distrust is removed. All 

 Theclas also have the same habit. 



The eggs of all Lycaenas are nearly globular, greenish-white, 

 the egg itself being green, but covered with a white network or 

 film which can be peeled off.
