ing to orange near the apex. Fringes lemon yellow. This outer half 

 contains a small black spot on the discal vein, and a submarginal row 

 of three larger black spots. The first of these lies across the interspace 

 above the ist median nervule ; the second across the 4th median nerv- 

 ule, and the third on the submedian vein close to the outer margin. 

 There is besides a very narrow marginal spot about the middle of the 

 outer margin. 



Beneath, the markings are reproduced, those on the primaries,, 

 especially near the apex, being broader and more diffuse ; all the light 

 portion of the primaries except near the apex are suffused with crim- 

 son, this color being most intense near the base and along the subcostal 

 vein. The secondaries ar^e somewhat paler and there is a crimson 

 streak on the basal third of the costa which does not appear above. 



Expanse of wings, 1.75 inches ; leitgth 0/ body, 0.80 inch.

This species, without exception the most beautiful of the American 

 Arctians, cannot be mistaken for any other. It belongs to the section 

 in which the veins are not clearly marked with a distinctive color. 

 The body reminds one of Epicallia virginalis, Boisd., the under wings 

 suggest the ? variety of Nemeophila plantaginis with red secondaries, 

 while the ornamentation of the primaries recalls E. caja. It is so un- 

 like any of our other species of the genus that further comparison is 

 unnecessary. It is with wuch pleasure that I dedicate this beautiful 

 insect to Dr. Yarrow, who was connected with the U. S. Exploring 

 Expedition in Arizona, and to whom 1 am indebted for many kind- 

 nesses.
