AKT. 5 GENERIC REVISION OF THE FOSSORL\L WASPS — PARKER 21 



and broader laterally than at midline ; fascia on tergite 1 very broad 

 laterally; continuous fascia on sixth tergite broad at midline and 

 narrow laterally ; continuous fasciae on sternites 2-5, broad laterally 

 and narrow medially ; legs, except line above on all femora and tibiae 

 and spot below on all trochanters and proximal ends of all femora ; 

 yellow. 



The flagellum, except the first and second segments, is more or less 

 reddish below ; above it is darker suffused with reddish basally. The 

 distal end of the apical segment is distinctly reddish. The flagel- 

 lum of the paratype shows but little of this reddish color except on 

 the apical segment. The wings are hyaline, narrow, and relatively 

 short. The pubescence is sparse and short, in fact, almost lacking. 

 The discal marks on the scutum and the lower part of the maculation 

 of the mesopleura show a tendency to the reddish color seen on the 

 flagellum. The male of the species is unknown. 



Length, 18 mm. Described from two specimens (including the 

 type) from Chapada, Brazil. 



Type and paratype. — In the Carnegie Museum in Pittsburgh, Pa.

Genotype. — Stiotia signata Linnaeus, designated by Parker in 

 1917. 



Wasps belonging to this genus have the ocelli completely obliter- 

 ated. The anterior cicatrice is circular in form but less than a com- 

 plete circle in extent and is not placed in a pit or upon a distinct 

 prominence or elevation. The middle of the vertex is depressed, is 

 distinctly lower than the level of the top of the eyes, whose inner 

 margins are somewhat divergent at the clypeus. The male has at the 

 apical end of the posterior border of the middle femur a distinct 

 notch and stout tooth. The sixth sternite of the male bears a con- 

 spicuous median area and the seventh tergite bears lateral spines and 

 its median part is emarginate at the apex.
