GENUS PTEROCON. 



Froserpinus^ Hiibner, Verz. bek. Schmett., p. 132 (1822?); 



Walker, List Lepid. Ins. Brit. Mus., viii., p. 97 (1856).

This genus resembles Macroglossa in shape, except that the 

 hind margins of the wings are excavated and angulated ; the 

 antennae are strongly thickened, and the abdomen but slightly 

 tufted. 



The type is P. proserpiiia (Pallas), a European moth, which 

 the late Mr. H. T. Stainton considered to be the most 

 beautiful of the SphiugidiC. We have figured an allied North 

 American species, and shall refer to F. prosetpimi again.
