This is a very rare species, a young one, collected in Costa 

 Rica, was sent by Mr. Garcia to Mr. Lawrence, who described 

 the species. It was the only specimen known. When I went 

 to Costa-Rica, in 1877, I collected two hne specimens, male 

 and female, at Rancho redondo. I described the male in the 

 P.Z.S. 1878, p. 68, and now I describe the female. The 

 types of male and female are in my collection, and the type 

 of a young male or female in the New York Museum of 

 Natural History (Ex. Coll. Lawrence).
