 CHARAXES. III. (Nymphalis a. 



CHARAXES CACUTHIS. 10. 13. 



Upperside. Male black, vrith several white spots, and a broad common band 

 of pale blue. Anterior wing with nine white spots, and a transverse band which 

 commences in a spot between the second and third median nervvdes and continue 

 the anal angle of the posterior wing, marked on the posterior wing by two white 

 spots. Posterior wing with two tads ; some white spots near the outer margin 

 submarginal band, rufous and obscurely marked between the apex and the first tail, 

 blue or green between the tail and the anal angle. 



Underside as in C. Etheta. 



Female dark brown, with a common broad band of white. Anterior wing with 

 several rufous spots : two of these spots, between the median nervules, large ; the 

 lowest spot forming part of the transverse band which ends at the middle of the 

 abdominal fold of the posterior wing ; on the underside it does not differ from the 

 male. 



Expan. S 3 in. ; ? 3 -f^ in. Hab. Madagascar. 



In the Collection of W. C. Hewitson. 



Although very closely allied to C. Etheta. this butterfly has. I think, the characters of a dist 

 species. The blue band on the posterior wing of C. Etheta is composed of well-defined spots. • 

 could scarcely be converted into the broad band of C. Cacuthis. The double baud of white spc 

 the anterior wing of C Etheta are also much further apart than they are in C. Cacuthis ; these same 

 spots also differ in colour in the female. On the underside the two species scarcely diner, t 

 the case with other species of the genus Charaxes. 



I find that I have been led into error in following what Mr. Westwood has done in " Doubleday 

 and Hewitson's Genera of Diurnal Lepidoptera," he having there adopted Nymphalis as the name of 

 this genus. Charaxes has the right of priority, aud must therefore be used.
