GrONiozTTs, Forster. 

 Three distinct species in this genus are in the collection and 

 may be thus tabulated : — 



The backward-directed branch of the basal 



nervure prolonged, joining the apex of the 



transverse medial nervure, and forming a 



small, closed, subtriangular discoidal cell. 



Coxae and femora black ; tibiae and tarsi 



honey-yellow G. nigrifemur, sp. n. 



Coxae and legs entirely honey-yellow G. Sancti-Vincenti, sp.n. 



The backward-directed branch of the basal 

 nervure ending abruptly, and not forming 

 a small discoidal cell. 

 Coxae and femora black ; trochanters, tibiae, 



and tarsi honey-yellow G. incompletus, sp. n.
