15. Caligo saltus, sp. n. (PI. XVII, figs. 1—1/) 

 Allied to Caligo ilioneus but easily sejaarable by the much moi'e 



steely-blue colour of both fore- and hind-wings. Fore-wing steely- 

 blue beyond the cell and just touching it at the lower angle a broad 

 pale-yellow band runs from the costa to just beyond nervure 1 b. 

 This band is rather paler than the equivalent in G. ilioneus and is 

 much less clearly defined in its edges being more obsolescent. Be- 

 yond the yellow band the colour is rich brown inclining to black. 

 A white dot is situated between nervures 8, 9 close to the costa. 

 Only rarely are two dots present as in G. ilioneus. The submarginal 

 brownish band is very obsolescent in the ,^ and in the $ is much 

 less well defined than in G. ilioneus. Hind-wing with the basal 

 half of wing steely-blue shot with rich purplish-blue. The mar- 

 ginal half of wing brownish-black. The blue colour of the basal 

 portion of the wing does not extend so far towards anal angle of 

 wing as in its near ally. Under-side very variable and in the same 

 direction as G. ilioneus. 

 Expanse 150 — 158 mm. 



Not rare about cocoa estates but much less common 

 than the following, and is to be found amongst denser 

 undergrowth, as a rule.
