known to me, though coming nearer certain species of Osmodes 
than any others. 1 have therefore not hesitated to erect a new 
genus for its reception.

Hab, West Africa. Common in the valley of the Ogové. 
I have specimens determined by Mons. Mabille and compared 
with his type, which show that the form figured by Karsch in his 
excellent plate is identical.

Hab. Tropical West Africa. Common at Gaboon and on Congo ; 
Togoland (Aarsch). 
The female differs from the male in not having the extremity of 
the abdomen white and having the wings broader. The figure of 
G. cretacea given by Snellen exaggerates : slightly the pale markings 
on the underside of the secondaries, while that given by Karsch 
does not show them as they are commonly found. I have speci- 
mens, however, which agree nearly with both representations, and 
which reveal that there is considerable variation in the distinctness 
of these markings. My collection contains a series of forty 
specimens taken at different times and places.
