Wings short and broad. Anterior wings with the costal margin slightly concave about centre ; 

 outer margin oblique, nearly straight or slightly rounded ; inner margin slightly concave at base and then 

 ainuated to outer angle (prominently in the male and obscurely in the female); first subcostal nervule 

 emitted at about one -third from end of cell, second near end of cell, third emitted a short distance from 

 apex of second.* Posterior wings convex at base and suddenly oblique to apex ; posterior margin rounded 

 and eonvcx. Eyes naked ; palpi long, the apical joint slender and pointed at apex ; legs stout, femora 

 pilose beneath ; antenna? gradually increasing in thickness from the base, and terminating in a somewhat 

 long and moderately thickened club ; thorax robust. Posterior wings in the male provided with a Jong tuft 

 of hairs near the base of cell, 



* Mr. Scudder remarks (Froc. Am. Ac. Arts & Sci. vol. X. p. 256 (1875)* "The name is* correctly spanking, preoccupied, 

 through l'oriice (Lam. Pol. 181(3)." The two namee do not, however, appear sufficiently similar to warrant the inconvenience 

 incidental to the substitution of a new generic natm\ 



f Mr. Moore deseribeB the subcostal nervules as four in number; Mr. Hewiwon corrects Moore, and sayB there are but 

 two ; according to my view there are three.
