The example first obtained is somewhat shattered and worn ; it 

 represents the greatest expanse of wing and is the palest specimen 

 of the three. 



At first I imagined that this species might be the male of Karsch's 

 Pettigramma spiculata ; but a careful study of his description has 

 satisfied me that his insect is the female of Walker's Salcujena 

 transversa, from Sierra Leone. Salagena differs chiefly from Arhela 

 in the upright hair on the anal segment instead of spatulate hair- 

 scales.
