black spot. The usual Exartema scroll-work is almost obliterated in this species. 

 There are three olivaceous patches, one on fold at inner fourth, one below fold just 

 beyond middle, and the third before anal angle; beyond the third is a patch of 

 whitish shining scales with reddish and brown strigulse, involving the anal angle 

 and forming the inner boundary for the red apical triangle. There is a paler streak 

 from inner fourth of dorsal margin to outer fourth of costa. The inner half of costa 

 is dotted with cream and black; in the middle of costa is a quadrate spot of red 

 and black scales; beyond this to apex the costal dashes are red and white, with a 

 black dusting in the red; at the outer third the costal dashes send down leaden 

 metallic lines which curve outward and run into the pale patch at anal angle, similar 

 lines rise from the costal dots before apex, join together and run to middle of outer 

 margin through the red patch and outside of the black spot. A small red and black 

 spot on the middle of the wing at the end of cell. Cilia shining pink, with a nearly 

 black patch at apex and three or four blackish scales between apex and anal angle. 



Hind wing smoky brown, cilia white; underside gray white, with a streak of 

 smoky brown below the cell and in the apex; cilia white. Underside of fore wing 

 smoky brown, except along costa and termen which are creamy yellow. 



Forty specimens: Black Mountains, N. Car., Valley, June 12; New 

 Brighton, Pa., ^ J una 3 to Aug. 12, F. A. Merrick; Algonquin, 111., July 8 

 to 13, Dr. Nason; Iowa City, Iowa, June 29, Prof. Wickham; Chicopee, 

 Mass., F. Knab; Pittsburg, Pa., Henry Engel. 



Nearest to E. corylanum Fern., but the latter is smaller and the promi- 

 nent dark triangle in apex is absent. 



— Exartema versicoloranum Clem. 



One specimen, bred from larva on black oak, issued June 5. Ten 

 other specimens captured in valley between June 2 to 26. 



Olethreutes nimbatana, var. montanana var. nov. 

 Plate VIII, Fig. 3. 



One 9 specimen, Mt. Graybeard, June 9. Larger and darker than 

 nivihatana, the outer edge of the dark area nearly vertical, not curving 

 inward as in nimbatana. The apex and extreme termen is much more 

 heavily overlaid with dark scales and .streaks. 



Hind wing very dark smoky fuscous, cilia broadly paler. Expanse 

 20 mm. 



Eucosma obfuscana Riley. . 



One specimen. Valley, June 11. I quite agree with Dr. Dyar in separat- 

 ing this from E. scudderiana Clem.-^
