This insect is very closely allied to G. miopteryx, from Peru ; but it is smaller in 

 size and the mediastinal vein of the elytra bears only one branch, instead of three 

 branches as in the latter. Nevertheless, it may be a small variety of the same species. 



G. forticeps, Sauss., from Brazil, is also an allied species of pale colour, perhaps a 

 variety of G. miopteryx.
