the apex similar to that of L. hauxwelli* The male is also like 

 liauxwelli in having the inferior appendages undeveloped. Fulgida 

 therefore belongs to the same group of species as hauxwelli and should 

 be so transferred in de Selys' synopsis of the genus, /. c, p. li. Like 

 guttifera, devillei* and doubtless other species, the young males of 

 fulgida have the apical brown spot of the hind wing not yet distinctly 

 developed.

The wings of young males are brown without any red (except the 

 apices which remain uncolored throughout life). Subsequently, red 

 appears in the midst of the brown and gradually occupies the whole of 

 the previously brown area. 



The wings of the female remain brownish throughout life, although 

 this color occupies a smaller area than in the male.
