Head large, with the front very full, bulging out much more than 

 usual. Palpi small and slender, not reaching to the front. Antennae either 

 pectinated, the branches fine, slender; or short and stout, ciliated, or simply 

 ciliated. Fore wings short and broad, triangular, the costa being much arched 

 toward the apex, which is much rounded, especially in the male; outer edge as 

 long as the inner in the male, shorter in the female. Hind wings large, long, 

 and rounded, extending far beyond the end of the abdomen. Venation much 

 as in Glaucopferyx, but the venules, especially the second and third subcostal, 

 are much shorter; the posterior discal venule very oblique, and not bent, 

 while there is hut one subcostal cell. Hind tarsus a little shorter than the 

 tibia. Abdomen long and slender, with a very slight anal tuft. The colora- 

 tion is peculiar, but very uniform in the different species. They are whitish- 

 gray, with about a dozen wavy, darker lines, somewhat broken between the 

 veins. The origin of the first and second median venule is black.
