10. Median portion of hind margin of genital plate, as seen from rear (actual 



dorsal view), fused almost from the extreme edge with an internal 



median thickening (fig. 33) impressus Fabricius. 



Hind margin of genital plate, as seen from rear, forming a thin shelf, 

 with no thickening visible at all near the edge (fig. 32) 11 



11. Fourth and fifth veins of membrane of fore wing fused for some distance 



near base (a character variably present in impressus also) ; hind wall of 



hypopygium concave inwardly orbicularis Horvath. 



Fourth and fifth veins of membrane of fore wing not fused near base (fig. 

 20) ; hind wall of hypopygium distinctly convex inwardly__caesus Germar. 



12. Genital plates angularly produced at the middle of their hind margins, the 



projecting portions overlying and almost entirely concealing the accessory 



genital plates (fig. 37) impressus Fabricius. 



Genital plates not angularly produced, the accessory plates fully exposed- -13 



13. Inner margins of genital plates most elevated and broadest posteriorly, their 



posterior margins concave (fig. 36) ; fourth and fifth veins of membrane 

 of fore wing fused for some distance near base (a character of variable 



occurrence in impressus also) orbicularis Horvath. 



Inner margins of genital plates most elevated medianly, their posterior mar- 

 gins not concave (fig. 31) ; fourth and fith veins of membrane not united 

 near base caesus Germar.

 ment of antenna, ring segment (2) and apices of 3 and 4, testaceous.

 notum laevigate, indistinct punctures visible only along trans vei-se

CANOPUS GLOBOSUS Horvath 



Canopus glohosus Horvath, G., Analecta ad cognitionem Oydnidarum, 1919, 

 p. 207 [Mapiri, Bolivia; Pachitea, Peru]. 



Head, pronotum, and anterior disk of scutellum, highly polished, 

 no punctures evident; scutellum except anterior disk with scattered 

 subobsolete punctures; specimens may be with, or without, aeneous 



» There are seven as yet unidentified names available for species of Canoptia, six of tliem 

 based on nymphs ; if these ever become identifiable, the new names proposed in this paper 

 are very likely to pass into synonymy ; they are presented therefore in a provisional sense.
