 and aedeagus removed; 45a, aedeagus. 



Male genitalia (slide 10679): Vesica armed with a group of four 

 long, slender cornuti arising from a common base, and a single, weak 

 cornutus dorsal to the group. Gnathos slender, about as long as 

 uncus. 



Type: Masafuera: La Correspondencia, 1150 m. (Jan. 28, 1955). 



Described from the unique type male. A distinct species resem- 

 bling North American forms. The genitalia are typical. S. dela can 

 be distinguished from matuta and pyraustoides, besides by the colora- 

 tion and markings, by the short gnathos which is equal in length to 

 the uncus. In the other two species the gnathos is appreciably 

 longer than the uncus. This species is further distinguished from 

 pyraustoides by the presence of cornuti which pyraustoides lacks ; from 

 matuta by the absence of the cluster of small, weak cornuti at the 

 base of the group of larger ones.
