basal two-thirds of marginal, the second and third subrnarginal, and 

 part of third discoidal cells, apex of anteriors narrowly, that of pos- 

 teriors more broadly, faintly fuscous, marginal cell long aud lanceo- 

 late, second subrnarginal rhomboidal, receiving first recurrent vein 

 near apex, third subrnarginal large, narrowed more than one-half 

 above, at which place it is slightly narrower than the corresponding 

 portion of second, nervures dark testaceous. Length 17 mm. 



Santarem (February). One specimen. Has a superficial resem- 

 blance to nob ills Fabr. 



Pompilus manifestatus Sua. (=Agenia mani/estata Sin.). 



Santarem. The only specimen represented agrees with the descrip- 

 tion of Agenia manifestata Smith, but it is not an Agsnia. 



Pompilus scrupulus n. sp. PL IV, f. 12. 



$ . — Black, clothed with silvery pile which is visible in certain 

 lights; clypeus short, more than three times broader than long, its 

 fore margin shining and broadly truncate ; front smooth, opaque, not 

 impressed; eyes reaching mandibles, converging above, at which 

 point they are separated by a distance about equal to the length of 

 the first flagellum joint; this latter not quite twice as long as the 

 second joint ; space between hind ocelli much less than that between 

 them and eyes; pronotum angulate behind, transversely bi-tumid ; 

 middle segment smooth, rounded behind, with a longitudinal medial 

 impressed line ; legs tending to brownish, rather strongly spinose, no 

 tarsal comb, claws bifid, calcaria short, the longer spur of hind tibiae 

 about equal to one-third the length of first hind tarsal joint ; abdo- 

 men ovate, testaceous at apex ; wings subhyaline, the anteriors 

 crossed by two fuscous fascia, which are separated from each other 

 by a yellow fascia, tips slightly fuscous, second subrnarginal cell 

 rhomboidal, scarcely half size of third, which at the top is not one- 

 third wider than the second. Length 11-12 mm. 



Santarem. Nine specimens. While the hind tibia? are not ser- 

 rated, yet this species is otherwise so close to some species of Salius 

 (Cyphononyx) that I am not certain but that it should be referred 

 to the latter genus. 



Pompilus regius Fabr. 



Chapada (December, January, April) ; Santarem. Twenty-five 

 specimens. 



Pompilus scutellatus n. sp. 



$ . — Black ; tegulse and anterior tibise and tarsi testaceous ; hind 

 margin of pronotum, base of abdominal segments 1-3, and calcaria,
