31. POLYCYRTUS (POLYCYRTUS) CIRCUMFLUENS, new species 



Female. — Length 12 mm. 



Closely related to ci/reolaris Cushman, from the foregoing descrip- 

 tion of which it differs only as follows : Eyes more strongly conver- 

 gent below ; propodeum weakly longitudinally impressed, without a 

 defined basal area, carina nearly straight; abdomen more slender, 

 second tergite fully three times as long as broad at base. 



Propodeum without piceous markings; second tergite with an 

 elongate oval subbasal white spot. 



Male. — Essentially like female. Annulus embracing flagellar 

 joints 8-16 (broken at this point). 



Type-locality. — Cayenne, French Guiana. 



Type. — Female in Paris Museum. 



Allotype.— C2it. No. 42195, U.S.N.M. 



One of each sex collected by E.. Benoist in 1914. 



32. POLYCYRTUS (POLYCYRTUS) MANNI, new species 



Female. — Length 12 mm. 



Vertex in front view shallowly concave ; f rons with scrobes poorly 

 defined, horn stout conical; eyes rather weakly convergent below, 

 inner margins faintly concavely arcuate; face impressed on each 

 side of middle, punctate above; malar space distinctly shorter than 

 basal width of mandible, not constricted, mouth fully as broad as 

 narrowest width of face; temples in side view rather narrow, oc- 

 cipital carina nearly parallel with posterior margin of eye, reaching 

 the hypostomal carina and without a distinct notch next to hyposto- 

 mal carina; temples from above oblique, flat, a little more than a 

 fourth as long as short dismeter of eye; diameter of ocellus two- 

 thirds as long as ocell-ocular line and only a little longer than post- 

 ocellar line; basal joint of flagellum hardly eight times as long as 

 thick. Thorax polished; pronotum longitudinally striate in mid- 

 dle of posterior edge; anterior lateral carina prominent, epomia 

 strong, angulating the weltlike humeral margin; prescutum rather 

 high; lateral lobes subsulcate; mesopleurum rugulose in upper ante- 

 rior angle, subalar tubercle not carinate, both prepectal and meso- 

 j)leural furrows f oveolate ; metapleurum coarsely punctate in middle ; 

 propodeum weakly impressed in basal middle, with a narrow median 

 groove from carina backward to a point between the apophyses, 

 carina arched sharply forward medially, spiracles broadly oval, 

 apophyses moderately long, slender and weakly curved, much nearer 

 to carina than to apex ; hind femur hardly twice as thick in middle 

 as at apex, inner calcarium two-fifths as long as basitarsus; areolet 

 large, recurrent and nervulus antefurcal, postnervulus broken slightly 

 above middle, nervellus at lower fourth. Abdomen stout, second
