66 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 115 



ocherous blotch, mixed with buff yellow, nearly reaching costa and 

 separated from a smaller similarly colored outwardly oblique patch 

 by an arm of ground color; in outer patch, which extends to cell, two 

 blackish spots; in cell, at two-fifths, a black spot and at end of cell 

 a small white dot; at apical third of costa an elongate triangular 

 white spot edged with pink along inner margin; beyond this spot 

 a few whitish scales; cilia grayish fuscous except those along apical 

 thu-d white with faint pink tinge. Hind wing fuscous; ciha grayish 

 fuscous except those around apical half of wing tipped with pink- 

 tinged white. Legs silvery white; forefemur brown on inner side; 

 fore tibia and first tarsal segment tinged with reddish ocherous; 

 mid tibia blotched with brown; hind tibia tinged ocherous white. 

 Abdomen fuscous dorsally, white ventrally; anal tuft with violaceous 

 tint; fu'st sternum with strong, median, eversible scale tuft in male. 



Male genitalia: Harpe broadest slightly before middle, costal 

 margin slightly excavate before cucuUus; saccular margin with 

 slightly curved digitate process extending about one-third distance 

 across harpe ; clasper a long arm from middle of harpe, terminating in 

 a cluster of strong setae directed toward and reaching saccular margin. 

 Anellus rectangular, deeply incised posteriorly forming two long, 

 pointed processes; on each side an additional long, slender process. 

 Aedeagus stout, curved, distally depressed, tonguelike; cornuti 

 numerous, consisting of closely appressed elongate group and stout 

 dentate series. Vinculum narrow, rounded. Gnathos transverse, 

 oval, spined knob. Socii small fleshy lobes clothed with long fine 

 setae. Uncus bifurcate, base as long as lateral arms. 



Slides examined: cfcf, JFGC nos. 4630, 5098, 10116, 10121. 



Type: Peru, Tingo Maria (Nov. 25, 1949, H. A. Allard), USNM 

 66373. 



Described from the male type and three male para types as follows: 



Peru: 2cf cT, Callao (Mrs. M. J. Pusey); cT, Chanchamayo (Dognin Coll.). 



The Chanchamayo specimen bears a label "Hypercallia melobaphes 

 Wals." in Meyrick's handwriting. 



The superficial similarity between contrasta and vexillata is striking, 

 but the genitalia at once distinguish the two. The anellus of contrasta 

 exhibits long, slender lateral and terminal processes but vexillata lacks 

 them. Moreover, midway on the saccular margin of contrasta there 

 is a pronounced digitate process that is absent in vexillata. 



The anellus and aedeagus of contrasta place it nearer melobaphes 

 than to any other species of this group but the digitate saccular proc- 

 ess of contrasta, absent in melobaphes, and the arrangement of the 

 cornuti immediately distinguish the two. 



Females of contrasta and vexillata are unknown and no comparison 

 with melobaphes can be made.
