THE CANADIAN ENTOMOLOGIST. (iM 



rather heavily with black ; a little silver at the junctions of the nervures 

 at base, and along the shoulder and inner margins ; a small spot in cell in 

 black ring. 



Body concolored with the wings, thorax somewhat brown ; beneath, 

 abdomen yellow-buff, thorax same, but with many red hairs ; legs red on 

 upper sides, yellowish below ; palpi yellowish within, red without and at 

 tip ; antennae black above, fulvous below ; club black, tip ferruginous. 



Female. — Expands 2.8 to 3 inches. 



Color less bright, over secondaries decidedly reddish next base and on 

 disk, the bases much obscured ; the markings heavier ; the marginal lines 

 on both wings more or less confluent, and' on primaries making a broad 

 and solid border ; the spots on secondaries as in the male, the mesial band 

 being broken into a series of separated crescents. 



Under side of primaries fiery-red, the outer corner of cell and next 

 interspaces yellow-buff ; the silver spots limited to the upper half wing, the 

 serrations below these sharp and black. 



Secondaries deep ferruginous, mottled a little with reddish buff; the 

 band encroached on as in the male ; the spots scarcely larger, and all 

 well-silvered. 



Found from Arizona to Montana. Taken in Colorado in 187 1 by 

 Mr. Mead ; by Mr. Morrison, in his trips to So. Colorado and to Arizona ; 

 by Mr. Nash and Mr. Bruce in Colorado. It seems to be an abundant 

 species in the latter State. From the time I received examples from Mr. 

 Mead this form was a puzzle to me. It looked a good deal like Aphro- 

 dite, but yet was considerably unlike the Atlantic Aphrodite. When 

 A/cestis was separated, this Rocky Mountain form seemed still more like 

 that, but was manifestly distinct from it. In 1884, I received eggs from 

 Mr. Nash, Pueblo, Col , and the females that laid them. From these I 

 bred the larvse and got three imagos, one male and two females, in 1885. 

 I had not felt sure before that this form of male belonged to these 

 females. The larvae of Aphrodite and A/cestis I am well acquainted with. 

 Both ar^ brown-black when mature, with no other colors than what is 

 present at the base of the tubercles, yellow or orange. In the present 

 species the larvae showed marked differences from those mentioned before 

 they were half grown, and the mature larva is quite another affair, largely 

 yellow, mottled black and yellow. As I shall figure the species and these 

 stages in Vol. 3, Butterflies N. A., now begun, I will not describe the 

 preparatory stages here. This is the species by mistake spoken of as
