HYMENITIS. 
Hymenitis, Hiibner, Verz. bek. Schm. p. 8 (1816). 
Lower discocellular of secondaries of male placed at right angles with the third sec- 
‘tion of the median nervure, and atrophied at its upper end; middle and upper disco- 
cellulars short but strong; upper radial strong, uniting with the subcostal close to its 
distal end; lower radial slender, sometimes atrophied at its proximal end. Tarsus of 
front leg of female with five joints, a pair of spurs on each of the first, second, and 
third joints. Female. Section a: secondaries with a long lower discocellular; middle 
discocellular absent ; upper discocellular very short, directed outwards; lower radial 
branching from the upper about halfway between the cell and the margin. Section 6: 
secondaries with lower discocellular curved near its upper end; middle discocellular 
meets the subcostal at an acute angle; upper discocellular absent ; lower radial distinct ; 
upper radial branches from the subcostal a little beyond the cell. 
(Species described: Section a, H. oto (Hew.); Section 6, H. sosunga, Reak.) 
The females of these two sections have very different structures in their secondary 
wings; and it may prove necessary to give them generic rank ; but as we have not yet 
been able to examine the South-American species with sufficient accuracy to enable 
us to ascertain the limits of each section, we prefer keeping them all under the name 
Hymenitis for the present. | 
The wing-structure of the secondaries of the males is the same in both sections, 
except that in H. ofo and its allies the radials are crowded closer to the subcostal than 
in the H.-sosunga group. 
The genus Hymenitis has a wide range in South America, being found in Southern 
Brazil, and throughout the eastern valleys of the Andes to Colombia, extending north- 
wards to Mexico, eight species being found within our limits.
