rugose-punctate and dull, bidentate ; tibiae constricted to beyond

 mandibles and antennae basally and frontal tubercles rufescent, a 

 curved red line round anterior ocellus and all legs more or less red. 

 Wings entirely hyaline.

Habitat: South Africa. Type in Nat. Hist. Mus., Berlin. 



This species may be best known by the rugose and dull temples, 

 the dense and irregular sculpture of pro- and meso-notum, dense

2 . Head large and globose, its longitudinal axis very elon- 

 gate, temples and occiput very long and convex. Frons arcuate 

 punctate ; all five frontal tubercles distinct ; vertex coarsely trans- 

 rugose ; occiput finely arcuate rugose, with distinct longitudinal 

 impression ; posterior margin of head sharply bordered. Basal 

 flagellar joints normal. Neck elongate, smooth, laterally obliquely 

 rugose ; semiannular trans-striate, posterior margin smooth. 

 Mesonotum strongly transrugose and punctate. Scutellum cen- 

 trally polished, laterally strongly punctate. Mesopleurse pubescent, 

 smooth, apical half diffusely punctate ; metapleurse alutaceous and 

 dull in front, coarsely punctate behind, separated from median
