apical sides. First abdominal segment long, nearly romid, slightly 

 broadening from spiracles to apex, postpetiole smooth and polished, 

 its disk slightly convex and with three minute foveae forming a tri- 

 angle between the spiracles; abdomen beyond smooth and jDolished, 

 second abdominal segment one-half as wide at base as at apex, Avith 

 an oblique groove laterally at base ; third abdominal segment slightly 

 wider at base than at apex, subequal in length to the second. Legs of 

 medium length, hind basitarsus equal in length to the four following 

 joints combined. Stigma triangular, radius at middle, length of 

 marginal cell on metacarpus twice the stigma, nervulus interstitial, 

 postnervulus broken at middle, areolet open behind; nervellus ver- 

 tical, broken below the middle, the first abscissa of radiella equal 

 to the first abscissa of cubit ella in length, first abscissa of mediella 

 strongly curved, obliterated at base. 



Black; palpi whitish; mandibles brownish; abdomen beyond the 

 spiracles of the first segment ferruginous; legs black, front femora 

 and base of middle femora brownish; front and middle tibiae and

POLYSPHINCTA (POLYSPHINCTA) VENATEIX, new species 



A robust species. In color and sculpture of propodeum near to 

 P. hurgessi Cresson, but distinct from that species in its larger 

 eyes and ocelli, shorter malar space, and sculptured abdomen. 



Female. — Length 9 mm, ovipositor 3 mm, anterior wings 5.05 

 mm. Head transverse, smooth, and sparsely punctate, clothed 

 with long hairs on the sides of face and mandibles. Face longer 

 than wide, produced below antennae; clypeus convex, rounded at 

 apex, its anterior edge somewhat depressed ; f oveo-ocular line longer 

 than the malar space, which is one-third as long as basal width of 

 mandibles; eyes large, slightly converging toward clypeus, slightly 

 emarginate opposite the antennae; temples rounded, their width 

 equal to about two-thirds of the short diameter of the eye; diam- 

 eter of a lateral ocellus greater than ocellocular line, which is about 

 equal to postocellar line and about one-half the ocelloccipital line; 

 occipital and hypostomal carinae well developed; notauli distinct, 

 subparallel, ending in a subquadrate, punctate area at middle of 

 mesoscutum; scutellum convex, margined at base only; mesopleura 

 smooth and impunctate, the furrow very wide, punctiform at base; 

 propodeum rugulose, the median carinae defined and ending at the 

 top of the posterior declivity; a short, strong median carina at
