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 ambulation 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-
