N0 - 3620 MICROLEPIDOPTERA, XV — DUCKWORTH 5 



occasionally may be forked; apex of gnathos slender, acute; harpe 

 with apical region equal or slightly longer than ampulla, ampulla 

 large, clublike with tendency for slight counterclockwise twist at 

 apical half. 



Female genitalia: Unknown. 



Type: In the British Museum (Natural History). 



Type-locality: El Porvenir, Peru. 



Distribution: Peru: El Porvenir, south Peru, 3300 ft. (no date) 

 Sani Beni, Lima (August); north Peru (no date); Peru (no date) 

 Huancabamba, east Peru, 6000-10,000 ft. (no date). Bolivia 

 Chimate, 760 m. (September). Costa Rica: Tuis (May, June). 



This species is recognized easily by the large clublike ampulla in 

 the male genitalia. In maculation it is very similar to the following 

 species T. whalleyi, the principle difference being the more pronounced 

 outward curviture of the sub terminal line on the fore wing. 



Walsingham (1912, p. 153) listed T. directrix as occurring in Central 

 America on the basis of a specimen in the U.S. National Museum 

 determined by A. Busck. Meyrick (1932, p. 288) questioned this 

 record, stating: "Walsingham (Biol. C.-Am. iv, 153) records T. 

 directrix from Costa Rica, on the authority of Mr. Busck; it is more 

 probable geographically that the species intended is geranomor'pha" 

 I have studied the specimen in question and compared it with the 

 types of both T. directrix and T. geranomorpha and find that Busck's 

 determination was correct. The distribution pattern this produces 

 is not uncommon in the family and actually is more feasible geo- 

 graphically than that suggested by Meyrick.
