Salius (Priocnemie) congruus n. sp. 



9 . — Head and thorax black ; legs and abdomen steel-blue, an- 

 tennal joints 8-12, fulvous, last joint dark at tip, scape and base of 

 flagellum beneath testaceous ; head large, much broader than thorax, 

 somewhat subquadrate ; clypeus rather flat, broadly truncate, three 

 times or more broader than long; front faintly impressed; eyes 

 almost reaching base of mandibles, slightly, if anything, converging 

 above, at which point they are separated by a distance greater than 

 the combined length of antennal joints 2 and 3 ; space between hind 

 ocelli much less than that between them and eyes; antenna? long, 

 setaceous, first joint of flagellum but little longer than second ; 

 pronotum angulate behind ; middle segment sloping gradually from 

 base to apex, slightly convex, slightly depressed in middle before 

 apex ; legs scarcely spinose, the serration of hind tibia? exceedingly 

 delicate, and indistinct, longer spur of hind tibia? about equal to 

 half the length of first hind tarsal joint; abdomen shortly subpetio- 

 late ; wings subhyaline, the tips and two cross fascia? of the anteriors, 

 dark, second submarginal cell subquadrate, scarcely half the size of 

 third, and receives the recurrent vein between middle and apex, 

 third submarginal narrowed about one-third to marginal, long, re- 

 ceiving the second recurrent vein between base and middle. Length 

 11 mm. 



Santarem. Two specimens. The thorax beneath, postscutellum 

 and apex of middle segment, more or less with silvery pubescence. 



Salius (Priocnemw) clypeatus n. sp. 



9 . — Black, with obscure steel-blue reflection ; flagellum beneath 

 and joints 4-7 entirely, yellowish apical joints black ; face, clypeus, 

 thorax beneath, postscutellum and apex of middle segment with 

 silvery pubescence ; head transverse, not much wider than thorax ; 

 clypeus subtriangular, its fore margin acute in the middle ; front 

 faintly impressed ; eyes almost reaching base of mandibles, converg- 

 ing above, the space between them at that point equal to less than 

 the combined length of antennal joints 2 and 3 ; distance between 

 hind ocelli less than that between them and eyes ; antenna? long, first 

 joint of flagellum longer than second ; pronotum subangulate behind ; 

 middle segment rather short, convex, depressed posteriorly, indis- 

 tinctly impressed ; legs scarcely spinose, serration of hind tibia? 

 delicate and indistinct, the longer spur equal to somewhat less than 

 half the length of first hind tarsal joint; abdomen shortly subpetio- 

 late ; wings subhyaline, the tips and two cross fasica? of anteriors,
