reaching mandibles, not converging, the space between them at top 

 not equal to length of first flagellum joint; space between hind 

 ocelli equalling that between them and eyes; front with faint im- 

 pressed line, and with the vertex distinctly striato-punctate ; first 

 joint of flagellum nearly one-third longer than the second ; pronotum 

 subangulate behind ; middle segment rounded, not impressed, the 

 posterior portion slightly depressed ; legs rather strongly spinose, 

 tarsal comb fairly well developed, claws with a sharp median tooth, 

 spurs reddish ; the inner one of hind tibiee fully two-thirds as long 

 as the first hind tarsal joint; abdomen with cinereous pile, apical 

 segments with sparse long hairs ; wings dark fuscous with bluish- 

 purple reflection, second submax-ginal twice the width of third at 

 top. Length 16 mm. 



Chapada (March). One specimen. 



Pompilus deceptus n. sp. PI. IV, f. 5. 



9 . — Similar to partitus as to coloration ; anterior margin of cly- 

 peus incurved ; front smooth or finely punctured, not striate ; space 

 between hind ocelli less than that separating them from eyes, space 

 between eyes at top equal to length of first flagellum joint ; legs as 

 in partitus, but the inner spur of hind tibiae equalling but little more 

 than half the length of first hind tarsal joint ; wings as in partitus, 

 except that the third submarginal is narrower at top, equalling less 

 than one-half the corresponding portion of second. Length 14-17 

 mm. 



$. — Colored like 9 , the thorax with faint purplish reflection; 

 face with pale pubescence; eyes not reaching base of mandibles; 

 antenna? stout, longer than head and thorax, joints of flagellum 

 rounded out beneath, its first and second joints nearly equal in 

 length, the first perhaps longer ; legs strongly spinose, longer spur 

 of hind tibiee four-fifths the length of first hind tarsal joint, claws 

 bifid, the inner process the shorter and truncate ; second submargi- 

 nal cell larger than third, which is much narrowed above, the mar- 

 ginal cell rather short and broad; abdomen depressed. Length 12 

 -13 mm. 



Chapada (February, April, September). Five specimens. Has 

 a superficial resemblance to partitus, but is distinguished by smooth 

 front, etc. 



Pompilus angusticeps n. sp. " 



$ . — Head, thorax and legs black ; abdominal segments 1-3 red- 

 dish, the remainder black ; face, scape beneath, sides of thorax
