Bnrmeister describes (Handb. d. Ent., il, p. 858, No. 60) both male aud female of 



BaiK/iiiiieo from Madras. Kambur says that he has described only the male [of "nan- 



ffuhtea Burm."] from Senegal. Baron de Selys states 



(?. c.,p. Ixiv) that sujuala Kamb. (Nevr., p. 117, only the 



female, locality unknown) is synonymous with sdiK/ii'niea 



Burm. If su/nata Ramb. and naiujtthiea Kamb. are difi'er- 



ent species, as seems probable, ftanfimnca Ranib. may be 



a varietj' of edivardsii, or founded on younger specimens 



thereof. It should be noted moreover, that exhvarihii p\^^\' ,.\ , , •■
