5. Paraiso, Canal Zone, January and February, 1911 (Busck); 

 Porto Bello, February, 1911 (Busck); Trinidad River, March, 1912 

 (Busck). 



RIFARGIA PRESBYTICA, new species. 



Light gray; at base of fore wing a curved black streak stained 

 with brown from base to inner margin at inner line; inner line double, 

 curved, dentate, cutting off a dark gray-filled blotch on costa; reni- 

 form constricted, with an inner appendage above; outer line double, 

 stained with brown, lunulate, followed by a row of round black 

 blotches, encircled by gray and clouded without the hne from costa 

 subapically and approxunate to outer line below; subterminal hnear, 

 black, dislocated into segments above and projected on the veins 

 below. Hind wing whitish at base, dark fuscous without; fringe 

 white. Expanse, 42 mm. 



Cotypes.—Thiee females, No. 15953, U.S.N.M.; Taboga Island, 

 Panama, February, 1912 (A, Busck); Sixola River, Costa Rica, 

 August, 1907 (W. Schaus). 



Closely allied to R. prxrupta Dognin from French Guiana, which, 

 however, lacks the basal arc and has the liind wing less whitish at 

 base. The Sixola River specimen is marked "-B. condita Schs. 

 fide B. M." but I can not associate it with the male type of condita, of 

 which we have no female. The Tuis specimen is marked "myconos 

 Schs. 9 " but the type of myconos from Peru is a female and clearly 

 distinct.

The type of clarH is a male with large black discal spots. The
