582 PROCEEDINGS OF THE NATIONAL MUSEUM vol. ns 



Hindwing subtrapezoidal, slightly narrower than or as broad 

 as forewing; costa almost straight or slightly undulate; apex rotundate; 

 termen flat or slightly sinuate; tornus broadly rotundate; dorsum 

 very slightly convex, strongly curved basally. Eight veins; Sc 

 almost straight; R and Mi more or less approximated in basal third, 

 then diverging; M2 and M3 parallel; M3 and Cui connate or slightly 

 separate at lower angle of discal cell; Cu2 from three-fourths of discal 

 cell; all three of anal veins present. No cubital pecten. 



Male genitalia. — Eighth abdominal segment with large lateral 

 coremata bearing clusters of long hairs. Uncus moderately long, 

 elongate-scaphiform, flatly calathiform or somewhat obcordate, in 

 last two cases on a narrow stalk, or equally broad, slightly flattened 

 dorsoventrad, and with a transverse, ventral carina; tip of a scaphiform 

 or calathiform uncus generally with an apical thorn directed ventrad 

 and often with a small papilla at base of this thorn; middle process of 

 gnathos short; socius weak, haired, more or less dilated, pendant, 

 and with a broad base. Tegumen rather broad with narrow pedunculi. 

 Valva in folded position rotundate-foliaceus, oblong; costa sometimes 

 strengthened, especially at base, occasionally with a rudimentary 

 harpe; sacculus generally somewhat dilated at base. Fidtura superior 

 as a simple, transverse bar; vallum penis generally with a more or less 

 large, finely spinose lamina praeputialis; fultm'a inferior rather high. 

 Aedeagus generally thick and somewhat stout, occasionally rather 

 slender, in both cases with a process at tip, and in distal portion 

 sometimes with little scobination; caulis practically absent; coecum 

 penis rather rudimentary; a strong generally conriform cornutus, 

 sometimes also a cuneus of minute, more or less numerous thorns. 



Female Genitalia. — Papillae anales pelmifonn, oblong, soft, and 

 haired. Sinus vaginalis wide, more or less infundibidar. Antrum 

 shortly tubular, as wide as sinus vaginalis or narrower, generally with 

 lateral colliculi, one on each side of antrum; no separate ductus bursae; 

 corpus bursae elongate, sometimes very long; cervix bursae not 

 difTerentiated, united with corpus bursae, generally stronger sclerotized 

 than latter and sculptured, and merely perceptible morphologically 

 as receiving ductus seminalis; in subgenus Pseudatteria cervical section 

 of corpus bursae broader than antrum, in remaining subgenera only 

 as broad as antrum, and fused with it; cestum generally present, 

 located in cervical section of corpus bursae, generally shaped as a 

 strongly sclerotized, elongate plate, as a rule with serrate margins and 

 a narrow, longitudinal carina; signum (if present) shaped as a rather 

 small, generally scobinate plate or an indistinctly outlined area with 

 or without a transverse carina. 



Remarks. — Among the Neotropical Tortricidae the species of the 

 genus Pseudatteria are the most striking moths, which, with their
