NYTHOBIA MINUTA, new species.

Kims to Zaporus in Schmiedeknecht's ^ key as well as in Foerster's 

 and Ashmead's. In the first it runs, because of the broad temples, 

 almost equally as well to NythoMa, although the costulae are dis- 

 tinct. Because of its very close similarity to the genotype of 

 NythoMa, 1 refer it to this genus.

 very shallowly emarginate opposite antennae; face very nearly as 

 broad as frons, together with clypeus slightly longer than wide; 

 malar space two-thirds as long as basal width of mandible ; antennae
