REVISION OF MOTHS OF CARPOSINIDAE 63 



Female genitalia (figs. 82, 100). — Lamella antevaginalis rela- 

 tively narrow at ostium, becoming broader anteriorally; posterior 

 margin simple, slightly curved inwards. Posterior third of ductus 

 bursae with papillae reduced, walls membranous except at sides near 

 juncture with lamella antevaginalis; anterior two-thirds of ductus 

 partly papillose, with papillae arranged in two broad bands extending 

 to corpus. Corpus bursae expanded and ovoid, with a pair of slender 

 furcate signa. 



Host. — Unknown. 



Distribution (map 5). — Presently reported only from Costa Rica. 



Discussion. — This unnamed species agrees in venation with C. 

 phycitana as described by Walsingham and may actually represent the 

 female of that species; however, largely due to the poor condition of 

 C. phycitana, a more precise comparison cannot be made, and any 

 further discussion will have to await the collecting of additional 

 material. 



Material examined. — One female: Costa rica: Orosi, 1500 

 m. [?], 1 9, (VNM). 



Carposina species, no. 2 



Figures 24, 32; Map 5 



Adult (fig. 24). — Wing expanse: 9, 19 mm. 



Head: Whitish with a pale suffusion of tawny along front (an- 

 tennae and labial palpi damaged) . 



Thorax: Collar and tegulae whitish; dorsum stramineous; venter 

 whitish. Legs whitish to tawny; tarsal segments indistinctly tipped 

 with white. Forewings stramineous, faintly marked with a few scattered 

 patches of brownish scales present mainly along costal margin, 

 termen, and at apex of discal cell. Veins 10 and 11 connate (fig. 32); 

 8 and 9 stalked one- third their length; all other veins arising separate 

 from cell. Hind wings pale gray; veins 3 and 4 slightly separate. 



Abdomen: Missing. 



Host. — Unknown. 



Distribution (map 5). — Known only from Volcan Sta. Maria, 

 Guatemala, which is situated in the Central American Volcanic 

 Upland. 



Discussion. — This species, represented by only one imperfect 

 specimen, is mentioned largely because of its superficial resemblance 

 to C. phycitana and its rather peculiar venation, which immediately 

 distinguishes it from Walsingham's insect. The forking of veins 8 

 and 9 in the primaries is similar to the condition present in the sub- 

 genus Epipremna, whereas the origins of 10 and 11 are most similar 

 to that found in the subgenus Trepsitypa. Because the origin of 

 these particular veins is believed to be relatively constant in this group
