CUPIDA GROUP 



Hairless apical margin of clypeus usually moderately wide; meso- 

 pleuron with or without a short carina extending obliquely down- 

 ward and backward from the front end of its transverse groove; 

 propodeum without erect hair, only with pubescence; brush on inner 

 side of hind tibia continuous to the apex; subgenital plate of male 

 ligulate or narrowly tectate, the apex rounded. 



Tibial spurs and face of both sexes blackish. 



The species included are the Nearctic obscura, euphorbiae, vogeli, 

 cwpida, submetallica, evansi, norata, and neglecta; and the Neotropic 

 Agenia argenteosignata Spinola 1851, Pompilus violaceipes Cresson 

 1867, Priocnemis (Priocnemella) wheeleri Banks 1925, Priocnemis 

 (Calicurgus) molinoi Banks 1925, Pseudagenia bruesi Banks 1928, 

 Ageniella purpuripes Banks 1938, and Priocnemella domingensis Banks 

 1944. Except for purpuripes, the Neotropic species have not before 

 been referred to Ageniella. The species obscura occurs in both the 

 Nearctic and Neotropic regions. 



6. Ageniella (Ageniella) obscura Banks 



Male: Forewing 4.0 to 4.5 mm. long; clypeus with a small blunt 

 median apical tooth, or sometimes the tooth absent; apical hairless 

 margin of clypeus very narrow and indistinct, or subobsolete (in the 

 other species of the cupida group, this margin is of appreciable width 

 and set ojff from the rest of the clypeus by a small groove); temple 

 without long hairs; mesopleuron without an oblique carina at the front 

 end of its transverse suture; third cubital cell about 1.45 as long as 

 high, receiving the second recurrent vein at its center; seventh sternite 

 narrowly tectate, without erect hairs. 



Female: Forewing 4.5 to 5.5 mm. long; clypeus with a small, 

 usually acute, median apical tooth; apical hau-less margin of clypeus 

 narrower than in other species of the cupida group and separated by 

 only a weak impression ; temple without long erect hairs ; mesopleuron 

 without an oblique carina at the front end of its transverse groove; 

 propodeum without wrinkles. 



This species is represented by the two subspecies below, dis- 

 tinguished by the color of the abdomen of the male and of the legs in 

 both sexes.
