 Acad. Nat. Sci. Phila. 



Discussion based on type and one other female, the latter in the 

 United States National Museum. 



Female. — Length 5.5 mm., antennae 4 mm., ovipositor two-thirds 

 the length of first tergite. Polished with propodeum posteriorly and 

 metapleura slightly roughened; propodeum areolated, only the ante- 

 rior transverse carina missing; first tergite much longer than wide, 

 longitudinally striate and with dorsal carinae strong to apex; following 

 tergites polished with deeply set-off rhomboidal areas, the furrows 

 more or less striate; malar furrow ]>resent, nearly as long as basal 

 width of mandible; temples slightly rounded, sharply sloping; radius 

 originating at middle of stigma; nervellus unbroken; nervulus post- 

 furcal; intercubitus nearly obliterated. 



Black with face, upper orbits, mouth, scape and pedicel beneath, 

 notauli, lateral margins of mesoscutum, margin of pronotum, tegulae, 

 spot below, scutellum, postscutellum, rhomboidal areas of tergites 

 except third, and legs (largely) white or wliitish; sterna and pleura of 

 mesothorax and metathorax red; hind femur with dark blotch above 

 near apex; articulations of trochanters blackish; hind tibia black 

 with broad white annulus; tarsi fuscous, the joints more or less

 in having the white of the head and thorax less extensive, the legs 

 more red, the metathorax entirely black, and tlie mesopleura and 

 sternum piceous with only a small red spot below on pleurum. 



Davis's type is from Florida, while the National Museum specimen 

 was taken at Rosslyn, Virginia, by R. C. Shannon. 



POLYSPHINCTA (ZATYPOTA) DICTYNAE Howard. 



Polysphincta dictynaellovff.nv, Ins. Life, vol. 1, 1888, p. 107, fig. 21, male. 



Type.— Csit. No. 2681, U.S.N.M. 

 Polysphincta minuta Davis, Trans. Amer. Ent. Soc, vol. 24,1897, p. 369, female, 



Type.—Acad. Nat. Sci. Phila. 



Discussion based on types of both names, a homotype of minuta, 

 and one other female. 



Originally described from a unique male, reared by J. H. Emerton, 

 from Dictyna voluins at Waltham, Massachusetts. The type is very 

 likely not fully colored, the darker colored portions of the body being 

 a rather pale brown, while in the females mentioned above they are 

 very dark brown to black. It was later redescribed in the female by 

 Davis from a specimen from Agricultural College, Michigan. 



Female. — Length 3.5 mm., antennae 2 mm.
