NEOTROPICAL MICROLEPIDOPTERA, VII — OBRAZTSOV 225 



Female genitalia: Erectile sacs (?osmeteria) on sides of postsegmen- 

 tal membrane of eighth segment, shaped as two large, coniform bags. 

 Apophyses anteriores and posteriores slightly dilated and rounded at 

 tips. Area around ostium bursae membranous, with weak sclerites 

 on sides. Antrum as mde as adjacent portion of corpus bursae; 

 ventral side of caudal portion of bursa copulatrix with a strongly 

 sclerotized area; signum shaped as an elongate, moderately broad, 

 slightly crescent plate. 



Type: Holotype, male (genitalia on slide 5797), Volcan de Chiriqui, 

 Chiriqui, Panama, 2000-3000 ft., 1881-1882 (G. C. Champion; 66559); 

 British Museum (Natural History). 



Other specimen examined: One female (genitalia on slide 14-Obr., 

 1963), Volcan Santa Maria, Quezaltenango, Guatemala, June; U.S. 

 National Museum. 



Remarks: The external characters of the specimen from Guatemala 

 indicate that it represents a female at cordigera which was described on 

 the basis of a male from Panama. Both specimens have similar 

 markings of the forewing; the narrow projection of the basal blotch 

 almost reaches the point of origin of the curved, subterminal fascia. 

 As yet, this feature has been known in cordigera only.
