tends from centre of costa to end of discoidal space, turning there toward 
inner margin, and ending one third inch above anal angle. The outer portion 
of the wing duplicates the fore wing except that the spots are only five in 
number and are much more prominent. 
Taken in May, 1899. 
Caligo gerhardi sp. nov. 
Habitat: Bolivia, Cochabamba district. | Expanse: 4.40 inches. 
Head and collar dark fulvous. Eyes brown. Palpi and legs fulvous. An- 
tennae dark fulvous, lighter beneath with a slight black annulation at base of 
each joint. Thorax dark mouse color above, fulvous beneath. Abdomen the 
same, but whitish on the sides. 
The general ground color of the upper surface is a rich regal purple. 
Costa of fore wing dark mouse color, generously covered with fulvous scales. 
Hind margin bordered with fulvous, a quarter inch deep at apex and lessening 
downward, disappearing at fourth median nervule. Within this the border is 
dark mouse color, three eighths of an inch wide, edged toward base with a 
broad jagged line of slightly lighter hue. At apex are three small white spots. 
The rest of the wing is regal purple, except a portion near base which is dark 
mouse color. 
The hind wing is the same. The hind marginal space, to the third median 
nervule, is light grayish brown, and bordering this nervule, half an inch above 
anal angle, is an elongated dead yellow spot about one third of an inch long. 
The dark mouse-colored space near base is covered with long nearly black hairs. 
The under side, owing to many irregular jagged black lines, etc., is difficult 
to describe. 
The under side of fore wing has a broad light fulvous border, nearly half 
an inch wide. In the centre of this, extending from apex to lower angle, are 
two jagged black or brownish lines one eighth of an inch apart, bordered on 
outer side with a bit of fulvous a shade lighter than the ground color. The 
costa is mouse color, covered generously with light fulvous scales. On inner 
edge of the marginal border the three apical white spots appear, bordered on 
marginal side with a dash of rich brown, which is black, however, at upper spot. 
In the space below is a small oblong ocellus, having four minute white dots on 
a black ground and all surrounded by a line of light fulvous. In the space be- 
low this is another smaller ocellus, one sixteenth of an inch in diameter, of 
similar coloring. These ocelli do not show on upper side. Inside of the 
light fulvous border is a space of varying width, one third to one half inch, 
with a linear border of blackish brown, transversely crossed by a mass of ful-
