1. Neoglaphyroptera nitens, n. sp. (PL VIIL, fig. 13, 



wing.) 



(^ , $ . Mesonotum shining black ; wings infuscated. Length 

 4 mm. 



Front black or blackish, yellow on the lower part. Face yellow. 

 Antennae blackish, the basal joints yellowish, about as long as the 

 thorax. Mesonotum, scutellum, and metanotum shining black, the 

 bristles of the same colour. Pleurae yellow in front ; reddish- 

 brown behind. Abdomen slender ; shining black or deep brown, 

 the proximal segments in front yellow or yellowish ; venter yellow. 

 Tuberculum of halteres black. Coxae yellow ; femora nearly of the

 tarsi of nearly equal length. Wings infuscated, the apex tinged 

 with blackish ; a brown spot at the origin of the cross- vein. 

 Middle and hind tibiae with stout spurs. 



Six specimens. 1000-1500 feet. In some of the 

 specimens the face is brown, the front wholly black, the
