The genus Salus will here, as is indicated by the sketch of the 
synonym given above, be taken in a wider sense than even Dahl- 
bom’s genus Priocnemis. I hold that the variation in the form of the 
claws on which was founded, for example, Dahlbom’s genera Cyphononya 
and Hemipepsis can only be considered useful for the establishment 
of groups of species all under one natural genus. Under Salzus then 
the following groups can be made :-— 
Ist Group (Subgen. Cyphononyz). 
Claws furnished with one obtuse arched appendix on their inferior 
edges, the length of which makes them appear to be double. The 
middle segment with an obtuse tubercle always placed before the 
stigmata. In the inner angle of the Ist discoidal cell a wing spot is 
indicated, but never clearly engraved (Cyphonony#, Dhlb.) 
np Group (Subgen. Priocnemis). 
Claws with one tooth on their inferior edges. No wing-spot in the 
inner angle of the Ist discoidal cell or at most only an indication of 
such (Priocnemis, pt. Schioedte, Dhlb,, Schenck, Taschenb ; Priocnemis, 
Thoms.). 
3rp Group (Subgen. Hemipepsis). 
Claws with two teeth on their inferior edges, The basal tooth is in 
many species, especially in the males, rudimentary and undetermined 
(in this approaching the genus Priocnemis). The inner angle of the 
Ist discoidal cell as in Pepsis, Macromeris, and Notocyphus engraved 
with a very dark wing-spot formed through the upper concave discoi- 
dal line. Middle segment mostly with an obtuse tubercle placed close 
before the stigmata as in the species of Pepsis (Hemépepsis, Dhlb.; 
Pallosoma, Pel.; Mygnimia, Smith). | 
4TH GROUP. 
Claws with many teeth ; on the inferior edges of the claws close to 
the strong curved apex spring a number of closely arranged cilia 
which have their apices going backwards to the claw ends. For the - 
rest the characters as in Hemipepsis. (Type : Hemipepsis heros, Gué- 
rin, Voy. Abyss., Lefeb., VI, p. 35, 4, T. 7, Fig. 9, 9.)
