brown, with one or more orange spots towards the anal angle 

 of the hind-wings beneath, and with white lines on the under 

 side, which has given rise to the name, " Hair-streaks," by 

 which they are popularly known. They have also a filiform 

 tail on the hind-wings. They are small Butterflies, measuring 

 from an inch to nearly an inch and a quarter across the wings. 

 The genus obtains its maximum of development in Tropical 

 America, but is not represented in the tropics of the Old 

 World. 



The antennas are more or less distinctly clubbed, the eyes 

 are naked and finely hairy, and the palpi are rather long. 

 The fore-wings are short, broad, and triangular, with the sub- 

 costal nervure three-branched, the first two branches rising 

 before the end of the cell, and the third running to the rather 

 pointed tip of the wing. The hind-wings are rounded and 

 generally tailed. The Inrvre generally feed on trees and shrubs; 

 and the Butterflies are usually to be found flying about their 

 food-plants, or frequenting brambles and other flowers growing 

 in bushy places.
