apex bluntly rounded. Harpe approximately rectangular; basal 

 process of costa somewhat produced but not strongly sclerotized, 

 fusing into membranous transtilla; saceulus folded upward toward 

 apex, not otherwise produced. Anellus consisting of ventral plate 

 and a more strongly sclerotized U-shaped dorsal band; dorsal margin 

 of ventral plate slightly concave ; dorsal band bearing a pair of very 

 long, stout spines. Aedeagus bent beyond middle; apical area ven- 

 trally compressed and slightly concave; the hind margin of this 

 concave area armed with short thornlike scobinations ; apex truncate.

/?e??i«.r7^.— Described from male type (Schaus, collector) and two 

 male paratypes (E. D. Jones, collector) from the type locality. In 

 addition to the above I have before me two small males belonging 

 to the British Museum and collected at Obydos, Brazil, by E. E. 

 Austin, February 2, 1896. They are smaller (18.5-20 mm) than 

 the type series, and their genitalia are about half the size of those 

 of typical carnigei^a. Otherwise there appears to be no difference. 

 Possibly they represent a race. On the other hand, they may be 

 merely stunted, aberrant specimens. Therefore I am not including 

 ihem among the paratypes. 



Female unknown.

Plate 26, Figures 13-13c 



Male. — Wings shining white. Fore wing with veins 11 and 12 

 approximate; -1 and 5 approximate. Hind wing Avith 4 and 5 con- 

 nate or very shortly stalked. Anal tuft white. 



Alar expanse, 36-38 mm. 



Genitalia with gnathos beaklike; lateral arms developed; lower 

 margin slightly convex; apical part stout, tapering to bluntly 

 pointed apex; apex upturned; inner surface with a weak, central, 

 longitudinal ridge. Uncus with basal part ovoid, produced back- 

 ■svard (cowllike), finely and densely scobinate; apical part stout 

 and but slightly tapered; apex bluntly pointed. Harpe with saceulus 

 produced at apex into a strongly sclerotized fold; basal projection 

 of costa produced, prominent; cucullus not narrowed, apex bluntly 

 rounded. Anellus consisting of ventral plate and a slightly rough- 

 ened dorsal membrane, ventral plate with upper margin concave, 

 lateral margins widely and deeply concave. Aedeagus with basal 

 part somewhat enlarged; apical half narrowing to blimt apex; 

 apex with lateral flange.
