the end of the cell; terminal dots black, nearly confluent; a narrow

 Bello, May, 1912 (Busck).

 upper angle of cell, 8-9 stalked, 10, 11 on the cell. Hind wing with 

 2 before the angle, median vein bifid, 4-5 stalked, cell short the cross- 

 vein not opposite 3, 6 at apex of cell, 7 and 8 separate, parallel. 

 Labial palpi upturned to vertex; maxillary palpi thickly fiUform, 

 bent inward; male antennse simple, very sUghtly thickened at base.

5. Trinidad Kiver, March, 1912 (Busck); Corozal, Canal Zone, 

 May, 1912 (Busck) and November, 1912 (C. P. Crafts); Porto Bello, 

 October, 1912 (G. F. Cleveland). 



Druce's characterization is insufficient to distinguish between the 

 three species before me, consequently I adopt Schaus's identification 

 of soraella in Costa Rican specimens, the male with a raised shining 

 black disk in the cell of hind wing below, adjoined by a hair tuft. 

 The specimens have very dark hind wings and do not agree well with 

 Druce's figure (Plate 101, fig. 28), which comes nearer to cinilixa. I 

 therefore suggest the alternative name drucella for this form. 



Type.— Male, No. 16373, U.S.N.M.; Porto Bello, October, 1912 

 (G. F. Cleveland). 



DRESCOMA CYRDIPSA, new species. 



Markmgs as in D. drucella Dyar and Megarthria peter seni Zeller, 

 rather larger than the former, smaller than the latter; distinguished 

 only by the male secondary character, an impressed pale fovea on 

 costa of hmd wing below, bending the veins into the cell, and followed 

 basally by a notched area of black scales. Expanse, 16 mm. 



Type.—MslQ, No. 16374, U.S.N.M.; La Chorrera, May, 1912 

 (Busck). Also five males and eight females, the latter presumably 

 of this species, with additional localities, Trinidad River, March and 

 June, 1912 (Busck); Porto Bello, May (Busck) and October, 1912 

 (G.F.Cleveland); Cabhna, May, 1911 (Busck); Corozal, Canal Zone, 

 February, 1911 (Busck); Tabernilla, Canal Zone, May, 1907 (Busck).
