Paratypes. — Puerto Rico: Same locality as holotype, 5 cf , Jan. 

 11-17, 1963, coll. P. J. Spangler (USNM). Described from a total 

 of six males. 



Host. — Unknown. 



Distribution (map 5). — Known only from the type-locality. 



Discussion. — Superfically this species may be distinquished from 

 the other members of Carposina by its predominantly whitish color. 

 The male genitalia show many diagnostic features, particularly in 

 the unique structure of the valvae and gnathos. In addition, the 

 stalking of both 3 + 4 and 8 + 9 in the primaries can be utilized as a 

 specific character as well as a subgeneric one. The venation 

 of all six specimens was examined and no variation was observed. 



The discovery of C. cretata now establishes the presence of at least 

 two species of Carposinidae in Puerto Rico, the other species being 

 C. bullata. 



Subgenus Epiprenina, new subgenus 



Type-species. — Carposina dominicae, new species. 



Adult. — Forewing (fig. 31) with vein 10 arising from discal cell 

 nearer to 11 than to 9; all veins separate except 8 and 9 which are 

 stalked one-third their length. Hindwings with only a vestige of 6 

 present at outer margin of cell; 3 and 4 usually connate; sometimes 

 sUghtly separate; discal cell relatively shortened; sUghtly less than 

 half the length of wing; 2 arising from outer fifth of cell very near 3. 



Male genitalia. — Uncus present, but reduced in size. Tegumen 

 relatively broad. Lateral arms of gnathos widely separated, elongate 

 and stout. Transtilla reduced to a thin band across middle; broader 

 laterally; a pair of digitate processes present near juncture with 

 valvae. Valvae relatively simple; ampulla absent. Vinculum rather 

 weak, expanding ventrally to form broad, indistinct saccus. Juxta 

 strongly bilobed. Aedeagus with apical haK expanded; a single, dense 

 cluster of cornuti present near apex; juncture of ejaculatory duct 

 above middle. 



Female genitalia. — Ovipositor relatively short; posterior apo- 

 physes approximately 1.5 X length of anterior pair. Lamella ante- 

 vaginalis relatively simple, reduced. Antrum distinct, walls densely 

 papillose. Ductus bursas slender, gradually enlarging to form long, 

 narrow corpus. Corpus bursae membranous, without signa. 



Discussion. — On the basis of venation, particularly in regard to 

 the stalking of 8+9 and the separation of all other veins of both wings, 

 this taxon can be easily distinguished from the remaining subgenera 

 of Carposina and from most other Carposinidae. It is probably closest 

 to Meridarchis with regard to venation, but differs from the type of 

 that genus in several features of the secondaries, such as: the near
