Figure 90 



Tyfe (male). — Black: labrum; mandibles, except tips; clypeus; 

 scape below ; area between antennae extended upward ; pair of spots 

 below anterior ocellus; broad anterior orbits shortened above; pos- 

 terior orbits narrowed and shortened above; posterior border of 

 pronotum; sides of prothorax, except large irregular spot in front 

 of tubercle connected with black of pronotum; short, lateral lines 

 above tegulae on scutum ; pair of conspicuous lateral spots on scutel- 

 lum; narrow, interrupted fasciae on metanotum; irregular spot on 

 lateral angles of propodeum; metapleura; larger spot above and 

 smaller spot below on mesopleura; broad fasciae on tergites 1-7; 

 fasciae on tergites 1 and 5 narrowly interrupted at midline; fasciae 

 on tergites 2-4 biemarginate on anterior dorsal border and deeply 

 notched at midline on posterior border; lateral spots on sternites 

 2-5; greater part of femora; tibiae; and tarsi; yello'W or white. 

 Maculations on posterior border of pronotum and on scutellum and 

 metanotum are white ; elsewhere they are light yellow. 



The clypeus is strongly and roundly arched and is scarcely carinate 

 at the base. The f rons is wide and between the antennae is weakly 

 carinate. The inner eye-margins are parallel. The flagellum is 

 black above, testaceous below, and none of its segments are spinose 

 or excavated. The anterior metatarsus bears six spines and the 

 middle femora are neither serrate nor dentate. The second sternite 

 bears a small, thin, laterally compressed process and the sixth a nar- 

 row, triangular, sharply pointed process. The seventh sternite bears 

 a median longitudinal carina that terminates at the apex of the 

 sternite in a process much resembling that on the second sternite. 

 The apex of the seventh tergite, is broadly triangular and roundly 

 pointed. The pubescence is normal and the wings are hyaline. 



Length 15 mm. Described from a single male (the type) bearing 

 the label, " Bahia Blanca, Argentina."

I have before me two females that have been referred to this species.
