in the other specimens distinct; transverse lines vague, formed by- 
increase of the dark sprinkling, tlie inner and outer, however, usually 
rendered more distinct by dark dots on the veins ; inner line from 
one-third costa to about two-fiftlis inner margin, oblique distad from 
costa to there bent (almost angled), and thence somewhat in¬ 
curved ; outer line starting (oblique distad) fi’om a rather distinct 
dark costal spot at about three-fourths, nearly parallel with termen 
from R2 to inner margin, but somewhat sinuous ; median line (shade) 
obsolescent in the type specimen, fairly distinct in the ^, where it 
is seen to be placed midway between the other lines, somewhat 
curved outside discal spot, and faintly sinuate basewards in sub¬ 
median area. Hiiidwing in the type without discal dot, which, 
however, is distinct in the other specimens ; two indistinct lines, 
the inner crossing discal spot (when this is present), the outer mid¬ 
way between this and termen. Terminal line of both wings dark, 
broadly interrupted at the vein-ends ; fringe pale, dark-spotted at 
the vein-ends. Underside without markings. 
Mendoza (foothills to Andes), type ($) and one ^ and $ 
in coll. L. B. Front, all taken February 8, 1903, by W. M. 
Bayne. Others in coll. A. F. Bayne, who describes it (in 
litt.) as “a fairly common species.” Not known from any 
other locality. 
In shape and general appearance, this species may be 
likened to Haracdia lotydata and its allies; but 
its small size and the weakness of the markings give much 
suggestion also of a species of Ptychopoda, with which it 
further agrees in the long-stalking of SC^ and in hind¬ 
wing. The insect may be somewhat variable, but un¬ 
fortunately none of the specimens are in very fresh condition. 
The general facies is pretty uniform, but in the $ the lines 
seem rather stronger, and are rather further apart, than in 
the ^s. In all the specimens there is some indication of 
darker shading in the distal area, but this is never very 
prominent, and perhaps sometimes tends to become more 
irregular, or concentrated towards the tornus, as in certain 
well-known species of both Kamalia and Ptychopoda.
