44. POLYCYRTUS (POLYCYRTUS) NEGLECTUS Cushman 



Polycyrtus neglectus Cushman, Proc. U. S. Nat. Mus., vol. 67, art. 23, 

 1926, p. 5. 



Much smaller than either lituratus or collinus but very similar in 

 structure and color, especially to the latter. The pleura are dis- 

 tinctly reddish and lack the black markings along the posterior mar- 

 gin and in sternauli and prepectus ; the legs are ferruginous without 

 black markings; the orbital white ring is sometimes complete and 

 sometimes interrupted; the arrangement of color on dorsum of 

 thorax, propodeum, and abdomen is as in collinus; the metapleurum 

 and propodeum vary from distinctly rugose to almost without 

 sculpture. 



In addition to the large type series I have examined five more 

 females and six more males from Connecticut, Pennsylvania, and 

 the environs of Washington, D. C.

Figures 7, 8 



Polycyrtus rufipleuris Szepligeti, Ann. Mus. Nat. Hung., vol. 14, 1916, p. 

 272, female. 



As I have identified this species it differs from all others known 

 to me in its convex but not prominent clypeus (fig. 7) ; the entire 

 lack of a carina along the anterior lateral margin of pronotum; 

 low, broad, uncompressed scutellum; rounded and noncarinate tu- 

 berculiform apophyses (at least in male) ; and short, thick, strongly 

 decurved first abdominal segment with spiracles only about three- 

 fifths of the distance from base to apex (fig. 8). The species is 

 known to me only from a single male specimen in the Paris Museum 

 and taken at an altitude of 1,000 meters in the Serra des Orgaos, 

 Province of Rio Janeiro, Brazil, by E. E.. Wagner. 



Male. — Temples from above strongly oblique, slightly convex, 

 nearly half as long as short diameter of eye; frons with shallow 

 scrobes, horn short, stout conical; vertex in front view slightly 

 convex; eyes weakly convergent below, comprising much less than 

 two-thirds total width of head; face minutely punctate and very 

 weakly impressed on each side of middle; clypeus very sparsely 

 punctate, convex, not elevated, rounded at apex; malar space much 

 shorter than basal width of mandible, cheeks in front view convex, 

 mouth broader than narrowest width of face; temples in side view 

 broad, occipital carina parallel with posterior margin of eye, sub- 

 prominent below, recurved and joining hypostomal carina behind 

 middle, latter low. Thorax polished; pronotum without either 

 anterior lateral carinae or epomia and with its anterior lateral
