COLIAS IV. 



COLIAS CHRYSOMELAS, 1-9. 



CoUas Chrysomelas (Chry-som'-e-las), Henry Edwards, Pacific Coast Lepidoptera, Feb., 1877. 



Male. — Expands 2 to 2.4 inches. 



Upper side greenish-yellow, not much obscured at base ; the marginal border 

 of primaries very broad, black, more or less dusted with yellow scales, cut nearly 

 to the outer edge by the yellow nervules, usually even-edged within, or slightly 

 erose, but sometimes roughly dentated, curving roundly at the apex, but little 

 advanced on costal margin, and on inner margin projecting a rather long spur ; 

 discal spot small, sub-ovate, black. 



Secondaries also have a broad border, cut to the outer edge by the two median 

 nervules ; not dusted yellow ; the discal spot usually wanting, but sometimes 

 orange, or indicated by a slight orange tint ; fringes of both wings pink, yellow at 

 inner angle of primaries. 



Under side of primaries lemon-yellow, deeper colored along costal margin, and 

 orange-tinted over apical area, often deeply ; except on inner margin and to 

 middle of cell, thickly dusted with fine brown scales ; the discal spot repeated, a 

 slight oval ring with yellow or sometimes pink-tinted interior; costal edge pink; 

 submarginal patches are sometimes present in the median interspaces, a small 

 cluster of black scales to each, but oftener there is no trace of these. 



Secondaries entirely orange-yellow, thickly dusted ; the discal spot pearl-white, 

 or perhaps roseate throughout or about the edge, in a red-brown, broad ring ; at 

 base a small patch of pink ; at outer angle a cluster of brown scales, never large, 

 often a mere trace ; some examples have submarginal patches in the median 

 interspaces only. Body covered with greenish-yellow hairs, the collar dull pink ; 

 under side yellow ; legs pink ; palpi yellow, pink at tip ; antennae and club 

 brown above, elsewhere pink, except that the end of the club is ferruginous. 

 (Figs. 1, 2.) Very rarely examples are of a deep yellow, as Fig. 5, and the mar- 

 ginal borders narrow and as in Fig. 7.
