Discussion: Through the courtesy of Dr. Irving Fox, of the 

 University of Puerto Rico, v^e have examined the holotype of castillae 

 Fox and find that it is the same species described in 1952 by Wirth as 

 gibsoni and by Ortiz as flochabonnenci. It is evident upon close 

 examination of the type slide that the fourth pale spot in cell R5 

 figured by Fox, the spot lying proximad next to vein Mi, is actually 

 a small hole torn in the wing. The single hind femur on the type 

 slide is dark at the apex. A close comparison of our material of 

 castillae and the excellent descriptions and figures of flochabonnenci 

 given by Ortiz convinces us that one species is involved. This 

 species was very numerous in the light trap collections from Lancetilla, 

 Honduras, and at Almirante, Panama, but occurs much more sparingly 

 in the vicinity of the Canal Zone. A remarkable feature of the female 

 of this species is the presence of sensoria on segment xi in addition 

 to those which are more commonly present in other species on iii 

 and viii-x.
