the tail is broader and double the length of that of TI. falkensteinii. The solitary 

 female of U. falke7istemu in the Museum is from Lagos, and suggests a very white 

 form of the genus Azanus, while the female of U. delatormn presents merely a paler 

 tint of the colouring of its male. 



In the typical section of the genus Uranothauma the male sex-mark is a discal 

 subtriangular mass of raised black scales extending from vein 7 nearly to vein 2 of the 

 fore-wing, as in U. crawshayi, TI. cordatus, and U. imbifer. There is no sex-mark at 

 all in U. antinorii ; while in U. poggei, felotus, artemenes, falkensteinii, and delatorum 

 the sex-mark consists of internervular and intracellular streaks from vein 7 to vein 1, 

 except that in U. poggei there are no streaks in the cell. In JJ. delatorum these 

 linear raised streaks of black scales, which are thicker basally, occur in the spaces 6-1 ; 

 one to each space, except in 1, in which there are two streaks, extending almost from 

 the margin to the base, and indicating the probability that this cell has been produced 

 by the fusion of two cells. The streaks in 4 and o are continued across the discocellulars 

 almost to the base of the discoidal cell.
