This widely spread species may readily be known by the blue of the basal part of 
the primaries and by the two distinct submarginal fulvous bands of the same wings. 
These are well represented in Cramer’s figure 1, which is otherwise rather exaggerated, 
a much more accurate representation of it being given by Hiibner 4. 
C. ilioneus only just comes into our fauna at Panama, where M‘Leannan captured a 
few specimens”. Dr. Boisduval states that it occurs in Guatemala?; but this assertion 
requires confirmation. 
c. Blue of upper surface restricted to secondary wings; central area of primaries much 
| paler than the margin. 
4. Caligo memnon. (Tab. XIV. figg. 1, 4.) 
Pavonia memnon, Feld. Reise d. Nov. Lep. p. 454*. 
Caligo memnon, Butl. & Druce, P. Z. S. 1874, p. 3897. 
Alis fuscis, marginibus late nigricantibus ; anticis medialiter et linea submarginali griseo-ochraceis ; posticis 
dimidio basali purpurascenti-cyaneo ; subtus fere ut in C. altoneo, area anticarum mediana ochrascente 
maculis et lineis obscuris obsoletioribus.

Veraguas (Arcé).— VENEZUELA. 
In his description of this species Dr. Felder very properly compares it with C. teucer, 
with which it is very closely allied, the chief, if not the only trustworthy, point of 
difference being the greater extent of the greyish-buff patch on the primaries and the 
more indistinct marks on the central portion of the primaries beneath—not very salient 
characters. 
How far it can be distinguished from C. taramela (Godt.), of Brazil, we are unable
