This species, named in honor of the savant who has communicated 

 the type specimen, and who has undertaken the preparation of a Cata- 

 logue of Ecuadorian Odonata, is perhaps related more nearly to G. ? 

 annectens Selys than to any other known species. Annectens is a 

 larger species, with 3-celled discoidal triangles on all the wings, a 

 longer pterostigma, and differently shaped superior appendages, the 

 latter having a strong triangular tooth, apparently replacing the stout 

 inferior spine of camposi, and the details at the apex are different. 



G. camposi will fall under rubric F with G. suasa in the synopsis 

 of Mexican and Central American species in Biol. Centr.-Amer. 

 Neuropt., p. 154.
