punctured and sparsely pubescent, strigose at the sides behind, 

 the sutural and two discal costae strongly elevated and smooth; 

 the basal half of the lateral margin, a small discal spot just 

 before the middle, a lateral interruj^ted fascia just behind the

I am indebted to M. Oberthlir for this very pretty and distinct 

 species ; it belongs to the first section of the genus with the 

 " mesosternal process long and incurved," although in coloration 

 and pubescent upper-surface, it more nearly resembles G. liiita,

 also a male, from Dr. Candeze, it was taken in the Upper Congo 

 district, and only differs from the type in having the Avhite 

 markings somewhat effaced.
