138 PROCEEDINGS OF THE NATIONAL MUSEUM vol. u4 



incorporates in the keys these 13 species as well as 6 more described 

 by Banks, Cresson, and Smith for the same region. 



The remainder of the species belong in the following genera 

 according to present-day classification : 



Ageniella: championi Cameron (Pseudagenia), collina Cameron 



(Pseudagenia), levipes Cresson (Pompilus), toUeca Cameron 



(Pseudagenia), utilis Cameron (Pseudagenia) 

 Allochares: azurea Cresson (Pompilus, Agenia) 



Calicurgus: calcaratus Cresson (Pompilus, Agenia), teapae Smith (Salius) 

 Dipogon: isthmica Cameron (Pseudagenia), melanocephala Cameron 



(Pseudagenia), nubifer Cresson (Pompilus) 

 Priocnemella: caerulipes Smith (Agenia), tabascoensis Cameron 



(Pseudagenia) 

 Priocnessus: cinciicornis Cresson (Priocnemis), orbiculata Smith (Agenia) 

 Priophanes: azteca Cameron (Pseudagenia) 



Banks ^ reported 17 South American species of this genus in his 

 key and papers, and there are two of Fox's types in the Carnegie 

 Museum in Pittsburgh which belong here. One of Bank's species, 

 auricoma, has an entirely different type of subgenital plate and 

 genitalia from the other species and is not included in this paper; it 

 probably should be placed in a new genus, as I have seen no other 

 genitalia or subgenital plate of its type. Twenty-five species are 

 described as new in the present paper, thus maldng 43 species from 

 South America in this genus. 



The species magdalenus, which I had tentatively placed in Auplopus, 

 does not belong here, as it has two basal hooldets at inside base of 

 volsellae; the genitalia is also distinctly different, as can be seen from 

 the photomicrographs in figures 52 and 53. It is therefore placed in 

 the genus Ageniella. 



The male of A. coerulosoma (Banks) was never described. There 

 is a male with this name at the American Museum of Natural History 

 in New York City. The specimen is not available at present so 

 could not be placed in the key. The photomicrographs of genitalia 

 and subgenital plate are shown in figures 60, 61.
