MESOSTENINI. 

 GLODIAIVUS gen. uov. 



Thorax more than three times longer than wide ; the parapsidal 

 furrows wide, stoutly transversely striated and extending close to 

 the base of the scutellura. Scutellum roundly convex, its sides not 

 keeled. Median segment, except at the base, distinctly closely trans- 

 versely striated and with one keel bordering the base of the striated 

 part ; the lateral spines are small, but distinct. Wings clear hyaline ; 

 the areolet small, closed at the apex ; the transverse median nervure 

 in the hind wings is broken well below the middle. The abdominal 

 petiole is long and slender, if anything longer than the 2nd segment 

 and is not much dilated towards the apex, the dilated part not form- 

 ing a post-petiole; its spiracles are closer to each other than to the 

 apex; the segments are smooth and shining. Metapleural keel ex- 

 tending close to the hinder coxae. 



The eyes are large and parallel ; the malar space is small ; the 

 front is depressed and is stoutly keeled in the middle ; the head is 

 nearly as wide as the mesothorax and is obliquely narrowed behind. 

 The face projects broadly in the middle and is clearly separted from 

 the clypeus by a curved furrow, which ends in the lateral fovese. 

 The antennae are long, ringed with white and slightly dilated towards 

 the apex; in the S they are serrate; the 1st joint of the flagellum 

 is longer than the second. 



In Ashmead's arrangement of the Mesostenini, this genus would 

 come in near Cnjptanura. 1 Bull. U. S. Museum, xxiii, p. 45.

 hinder femora and tibiae black, the hinder tarsi white, the extreme base and 

 apex black, the wings clear hyaline; the nervures and stigma black; the an- 

 tennae black, the flagellum broadly banded with white in the middle, f; %
