line crossing the fuscous patch which is placed at the apex of the 

 cell, and the outer line being nearly continuous with the oblique 

 apical streak. In between these two lines there are at most 

 faint traces of two or three other lines parallel with them. In 

 sovialicum, on the other hand, the three additional lines are 

 quite distinct, the first and second additional lines being in 

 the male nearly, and in the female fully, as well marked as the 

 proximal line. In this character H. r. somalicum represents 

 an ancestral stage. 



The genitalia do not appear to differ from those of II. r. 

 roseipennis.
