ANTHOCHARIS II. 



pale gray hairs at top and sides ; antennse white above, yellowish below ; club 

 white above, yellow below and at tip. (Figs. 1, 2.) 



Female. — Expands 1.4 inches. 



Color of male on both surfaces, and similarly marked ; between the ends of 

 the apical bars are black scales in considerable number, suggesting a cross band, 

 and next apex are more such scales than in male. (Figs. 3, 4.) 



EosA was described from 3 s 3 ?, sent me by the late Jacob Boll, and taken 

 by him on one of his expeditions to the extreme west of Texas, in 1878. He 

 informed me, in answer to inquiry, that he took several more, and all were of 

 the same type, particularly having reference to the markings about the apices 

 of fore wings. The species is very near to Olympia, figured in Vol. II of this 

 work. In liosa the apical area is immaculate in the male, except for a few 

 loose scales next costal margin, a little distance from the apex. In the female 

 there are somewhat more of these scales, and a nebulous connection of the two 

 marginal bars. (In the Plate, Fig. 3, this last feature is a little too pronounced, 

 the flecking in the insect being no heavier in this than next the apex.) 



The first known examples of Olympia, 1 j 1 5, were taken a,t Coalburgh, W. 

 Va., April, 1871. The description soon after published in Transactions of the 

 American Entomological Society, HI, p. 266, mentions " a large gray patch at 

 apex, partly replaced by white," — that is, a gray patch with one or more in- 

 terior spots or patches of white. Nothing is said of a definite bar on either 

 margin. In the insects, which are now before me, the inner edges of the gray 

 patch are somewhat blacker than the rest, especially next the margins, but there 

 is nothing of a definite bar. The description in Volume II was rewritten, and 

 gives the apex as covered by a gray sub-triangular patch, " terminating on either 

 margin in a small spot of darker color ; " and the figure of the male accompany- 

 ing shows a pale patch filling the apical area limited on the margins by spots or 

 clusters of scales of darker color. 



Since 1871, Oh/mpia has been taken in all the States lying west of West Vir- 

 ginia, to Nebraska, and in Colorado. The species seems particularly abundant 

 at Whiting's, Lake County, Indiana, and I have seen many from that locality. 

 One of these is represented in Fig. 5, and all the Indiana examples which I have 

 seen have been near to this, showing a patch of solid pale black with a small 

 white interior patch next costa in the direction of the base. 



In both the descriptions of Olympia spoken of, I mentioned a single male as 

 being in the Museum of Comparative Anatomy, at Cambridge, Mass., also from 

 Te.xas, and by Mr. Boll. This was taken at Dallas, and I considered it to be the
