Salius (Priocnemia) rufitarsus n. sp. 



9 • — Black ; antennae except five last joints, all the tarsi and fore 

 tibia?, reddish ; pubescence of head and thorax sparse, almost want- 

 ing ; clypeus rather large, fore margin broadly subtruncate, less than 

 three times broader than long ; front impressed ; eyes separated from 

 base of mandibles, space between them at top equal or greater than 

 length of antennal joints 2 and 3 ; space between hind ocelli less 

 than that between them and eyes ; antennae rather stout, the first 

 joint of flagellum nearly one-quarter longer than second; pronotuni 

 angulate behind ; middle segment short, rounded, with some trans- 

 verse folds, or rather transversely rugose, not impressed ; legs toler- 

 ably spinose, hind tibiae strongly serrated, its longer spur equal to 

 barely one-third the length of first hind tarsal joint; abdomen 

 clothed with pale hairs at apex, shortly subpetiolate ; wings sub- 

 hyaline, tips darker, crossed by two dark fasciae, second submarginal 

 narrowed about one-quarter above receiving the first recurrent vein 

 a little before middle, third submarginal much larger, narrowed 

 about one-third above, and receiving second recurrent vein in the 

 middle. Length 10 mm. 



Chapada (April). One example. 



Salius (Priocnemis) citricornis n. sp. 



9- — Black, with cinereous pile; head and thorax with rather 

 long sparse pale pubescence; flagellum except basal joints above, 

 pale yellow; tarsi rufo-testaceous ; clypeus broadly subtruncate, 

 scarcely three times as broad as long; front, not impressed ; eyes 

 not or scarcely converging above, reaching base of mandibles, the 

 space between them at top about equal to the length of antennal 

 joints 2 and 3 united ; space between hind ocelli less than that be- 

 tween them and eyes; antennae slender, first joint of flagellum about 

 one-sixth longer than second ; pronotum angulate behind, dorsulum 

 strongly convex ; middle segment subrounded, rather declining from 

 base to apex, not distinctly impressed ; legs tolerably spinose, the 

 serration of hind tibiae, however, not very distinct, the longer spur 

 of the latter nearly one-half as long as the first hind tarsal joint; 

 abdomen subpetiolate ; wings subhyaline, the tips of the anteriors 

 and two cross fasciae, fuscous, third submarginal cell nearly three 

 times the length of second, receiving the second recurrent vein be- 

 tween base and middle, second submarginal narrowed one-quarter 

 above, receiving first recurrent vein in middle. Length 8 mm.
