THE GENUS PHILOBIA DUPONCHEL, AND SOME 



REPRESENTATIVES IN OUR FAUNA. 



(LEP., GEOM.) 



By Richard F. Pearsall, 



Brooklyn, N. Y. 



The genus Philobia was established by Duponchel in 1829, having 

 notafa Linn., a European species, as its type. Curtis, in 1826, pub- 

 lished his genus Macaria, of which liturafa (Clerck.), also a European 

 species, is type. The most obvious difference between these types is 

 presented in the structure of the hind legs of the male. In nofata the 

 tibia is but slightly swollen, with a small external pencil of hairs, and 

 the long tarsi equal about two thirds its length, while in Utiirata the
