Poritia, Moore, Proc. Zool. See. 1865, p. 775 ; Hewits. Ills. Diiirn. Lep., Lye. p. 213 (1878). 



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 

 smuated 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.t Posterior wings convex at base and suddenly oblique to apex ; posterior margin rounded 

 and convex. 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 long tuft 

 of hairs near the base of cell. 



* Mr. Scudder remarks (Proc. Am. Ac. Arts & Sei. vol. s. p, 256 (18751, "The name is, correctly speaking, preoccupied, 

 througli Porifcs (Lam. Pol. 1816)." The two names do not, however, appear sufficiently simUar to warrant the incouvcnience 

 incidental to the substitution of a new generic name. 



t Mr. Moore describes the subcostal nervules as four in number ; Mr. Hewitson corrects Moore, and says there are but 

 two ; according to my view there are three.
