Brazil, Jan. 10, 1931"; three male paratypes: "(J. F. Ziran), No. 9, 

 Rio de Janeiro, 31-1-29, 1-3-27, 28-1-30." 



The species is related closely to the preceeding one, T. directrix; 

 however, the short ampulla expanded basally in the male genitalia 

 serves to distinguish T. whalleyi from all other species. 



The maculation distinction between the two species was described 

 in the remarks on T. directrix. 



I take great pleasure in naming this species for my friend and col- 

 league Mr. P. E. S. Whalley, lepidopterist at the British Museum 

 (Natural History), who has been of great aid in my study of the 

 family Stenomidae. 



Thioscelis lipara, new species 



Figures 9, 10; Plate 1 (Fig. 3); Map 1 



Alar expanse 53 mm. 



Antenna light brown. Head as for T. directrix. Legs as in T. 

 directrix except hind tibia with less pronounced dark brown lateral 

 line. Thorax and abdomen as for T. directrix. Forewing ochreous, 

 overlaid with light brown; a small, distinct S-shaped black spot on 

 median third near costa surrounded by a small patch of ill-defined 

 black dots; transverse sub terminal and terminal lines complete rather 

 than composed of dots as in previous two species, only slightly curved. 

 Cilia ochreous. Hindwing ochreous lightly overlaid with gray. 

 Cilia ochreous. 



Male genitalia (slide WDD 3658, type) : Uncus recurved, swollen 

 at apex, with distinct apical groove; apex of gnathos broad, acute; 

 harpe with apical region equal to or slightly shorter than ampulla, 

 ampulla falciform, outwardly curved. 



Female genitalia : Unknown. 



Type: In the British Museum (Natural History). 



Type-locality : Fonte Boa, Amazonas, Brazil. 



Distribution: Known only from the type-locality. 



Described from the male holotype (S. M. Klages), Fonte Boa, 

 Amazonas, May 1906. 



This species is distinguished easily by the falciform ampulla and 

 broad apex of the gnathos in the male genitalia. On maculation it 

 differs in having a small, distinct S-shaped black spot on the median 

 third of the forewing near the costa.

 face whitish; second segment of labial palpus light brown with dark
