Ashanti {Broohing). 4 specimens. B.M. 



Not an uncommon species in Collections ; it seems gene- 

 rally to be considered as an extreme variety of R. Ceres, 

 but as no intermediates have yet appeared, this is a gra- 

 tuitous assumption and nothing more. 



18. Romalcosoma Permixtum, n. sp. 



^. Above like R. JanettaS, excepting that the yellow 

 band of primaries is converted into a subtriangular bifid 

 patch, the bases of all the wings are black, and the red 

 subcostal spot of secondaries is wanting : primaries below 

 as in R. Crocheri, excepting that there is a spot of reddish- 

 orange l)etween the two black spots forming the base of 

 the triangle in discoidal cell ; secondaries as in R. Cypa- 

 rissa, excepting that the basal i^atch is reddish-orange shot
