specimens of Microlepidoptera in the British Museum (Natural History) 

 described by Edward Meyrick, vol. 4, p. 42, pi. 20, figs. 2-2c. 



Adult (fig. 14). — Wing expanse: 9, 11-13 mm. 



Head: Whitish to light brown. Antennae unicolorous, light brown 

 to pale fuscous. Labial palpi fuscous, slightly irrorated with light 

 brown; dorsal scales and extreme apices of second and third segments 

 light brown; inner surface of second segment mostly whitish to light 

 brown. 



Thorax: Whitish to light brown, scale apices often of a lighter 

 color than base; venter of thorax paler, usually whitish. Pro- and 

 mesothoracic legs fuscous ; apices of tibial and tarsal segments whitish 

 to light brown; metathoracic legs whitish, faintly irrorated with pale 

 brown. Forewings mottled with various shades of brown; basal trans- 

 verse band of fuscous present; five fuscous spots usually distinguish- 

 able along costa; a rather large, elongate, fuscous spot covering outer 

 half of discal cell usually distinct even in rubbed specimens; marginal 

 fringe fuscous, scales tipped with light brown to dusky white. Hind- 

 wings grayish at base, becoming darker toward outer margin. 



Abdomen: Light brown to tawny above, more whitish beneath. 



Female genitalia (figs. 81, 99). — LameUa antevaginalis lightly 

 sclerotized, variable in outline, roughly triangular; posterior margin 

 usually sinuate, with a slight median depression, nearly truncate in 

 some forms and more projected posteriorally in others. Ductus 

 bursae and antrum indistinguishable, of approximately same diameter 

 throughout length, becoming slightly enlarged toward corpus; walls 

 heavily reticulate. Corpus bursae abruptly enlarged, spherical; junc- 

 ture with ductus bursae sharply delineated by abrupt termination 

 of thickened walls of ductus; furcate arms of signa relatively short; 

 one arm of each signum frequently subdivided to form a short second- 

 ary fork. Inception of ductus seminalis below middle of ductus bursae. 



Type. — ^Holotype, 9; in the British Museum (Natural History). 



Type-locality. — Bartica, Guyana. 



Host. — Unknown. 



Distribution (map 4). — Present records, although scattered, 

 suggest this neotropical species to be rather \\'idely distributed. It 

 is known to occur from the Dominican Repubfic south through the 

 Lesser Antilles to Guyana; it has also been found in Peru. The largest 

 series of Carposina bullata collected thus far is from Dominica where 

 it is found over much of the wetter parts of the island from near sea 

 level to elevations exceeding 2,000 feet. 



Discussion. — The female genitalia of this species appears quite 

 different from that of the other members of the genus. After the 

 male is discovered and more information thus made available, it may 

 become necessary to recognize this taxon as a separate genus. The
