ART. 19. MOTHS OF THE GENUS DIATEAEA DYAR AND HEINRICH 5 



Genitalia figured from specimens from Lakeland, Fla. (male) , and 

 Orlanda, Fla. (female). 



Types. — In National Collection. 



Type localities. — Dade City, Fla. {lisetta) ; Corozal, Canal Zone, 

 Panama {camcellalis) ; Teapa, Tabasco, Mexico (adulcia). 



lESTA MOROBE Dyar 



Figure 46 , 1 



lesta moi-ohe Dyab, Proc. U. S. Nat. Mus., vol. 51, 1916, p. 37. 



Only the female type is before us, differing from guapilella in the 

 presence of a distinct outer line. 



Male, larva and life history unknown. This may prove to be a 

 varietal form of guapilella with which it agrees in genitalia. 



Genitalia of type figured. 



Type. — In National Collection. 



Type locality. — Teapa, Tabasco, Mexico. 



lESTA GUAPILELLA (Schaus) 



Diatraerupa guapilella SchaUvS, Ann. Mag. Nat. Hist., ser. 8, vol. 11, 1913, 

 p. 240. 



Only the female type is before us. 

 Male, larva and life history unknown. 



Female genitalia similar to those of lisetta except for a stronger 

 chitinization of the ductus and neck of bursa. 

 Type. — In National Collection. 

 Type loccdity. — Guapiles, Costa Rica. 



TRINIDADIA, new genus 



Front slightly bulging, smooth. Labial palpi porrect and down- 

 curved, extending over twice the length of the head. No ocelli. Maxil- 

 lary palpi triangularly dilated with scales. Antennae long, pectinate- 

 pubescent in the male, filiform in the female. Fore wing with vein 3 

 from well before end of cell; 4 and 5 stalked; 6 well below apex of 

 cell; 7 from apex of cell; 8 and 9 long stalked from apex; 10 from 

 before the apex; 11 anastomosing with 12. Hind wing with vein 3 

 from well before end of cell ; 4—5 long stalked ; 6 from apex of cell ; 

 7 anastomosing with 8. 



The genitalia show no characters to distinguish the genus from 

 Diatraea or lesta. The genitalia of the type, however, easily dis- 

 tinguish it specifically from anything in either of these genera; 

 and the hind wing venation and strongly pectinate antennae readily 

 separate the genus. 



Genotype. — Diatraea mininiifacta Dyar.
