Its distinctive differences from Cora, and indeed from the 

 whole legion Thore of de Selys (1869), are the unbranched

 between Cm and Cu2, and of only a single row between Cu2 

 and the hind maro^in of the wing. 



Fig. I.— Venation of Miocora peraltica cf , Peralta, Costa Rica, August 8, 1909 From 

 photograph by Mr. H. A. Walters. See text for an explanation concerning the 

 front wing. 



The venation is displayed in the accompanying figure where, 

 owing to the longitudinal folding of the front wing, ^Ii-3 and 

 AIi-2 for a short distance distal to the separation of M3 is 

 not shown as distinct from R, as it actually is in both front 

 and hind wings, and as shown in our figure of the hind wing.
