BIOLOGICAL PAPERS. 323 



triaogle; cheeks shining, distinctly punctured, the punctures well separated; 

 mandibles shaped like a cornucopia, the tips blunt and not touching, broader at 

 base than the malar space is high: antenca? thirty-two jointed, scape and pf di- 

 cellum together easily as long as the first two joints of the flagellum combined, 

 first joint of the flagellum nearly twice as long as wide, the two succeeding joints 

 longer than wide, the joints following theee, excepting the ultimate joint, wider 

 than long. Thorax shining and distinctly punctured; dorsulum with no parap- 

 sidal grooves whatever, most of the punctures well separated; mesopleura purc- 

 tured very like the doreulum, impressed above the middle along the posterior 

 margin, a faint indication of a cryptine groove on the anterior half of the scle- 

 rite close to where it joins the mesosternum; scutellum sparsely punctured, al- 

 most rigid laterally by the prolongation of a fold of the posterior lateral margin 

 of the mesonotum; the postscutellum more finely punctured than the scutel- 

 lum; metanotum closely, almost rugulosely punctuate; superior face of the 

 mesonotum bounded posteriorly by a rather sharp curved ridge, with a very 

 short basal area confluent with the lateral areas and with a spade-shaped areola, 

 the spiracles in the lateral areas very long and extending obliquely back- 

 ward and outward, the posterior face of the metathorax divided into three 

 areas by rather strong ridges, the petiolarea a little wider than the areola, 

 occupying the middle ;^ metapleura with well-separated distinct punctures on 

 a polished surface; wings faintly smoky, tinged with yellowish especially at 

 base; areolet pentagonal, the radial side on half the length of the trans- 

 verse cubitus, and equal to the length of the second side formed by the cu- 

 bitus, the first side formed by the cubitis and the transverse cubiti of equal 

 length ; the recurrent nervure broken a little below the middle by a short stump 

 of a vein externally; the diecocubital nervure broken by a ehort stump of a vein 

 a little before the middle; transverse median nervure interstitial with the basal 

 nervure; transverse median nervure of the posterior wings broken well below 

 the middle about at the junction of the basal third with the middle third; legs 

 very robust, the posterior cosa? rather pear-ebaped, nearly globular, the anterior 

 femora less than three times as long as broad, the middle femora about three 

 times as long as broad, the posterior femora a little more than three times as 

 long as broad, the tibia? of posterior legs normal at base or nearly, at apex nearly 

 as broad as the posterior femora in the middle. Abdomen distinctly punctured; 

 the petiole infundibulifoim, more than twice as wide at apex as at base, shining 

 and with well-separated punctures, laterally with a groove and with a ridge from 

 the spiracles to the posterior margin; the second, third and fourth segments 

 with smaller, closer punctures than the petiole, appearing dullish; the fifth 

 segment and beyond shining and indistinctly punctured or sculptured. Incon- 

 spicuously covered with silvery pubescence which is long and most apparent on 

 the clypeus, anterior margin of the labrum and the metathorax. Ferruginous; 

 sutures around the insertion of the wings laterally and posteriorly, around the 

 scutellum and postscutellum and more or less of the apical third of antennae 

 black; middle third of antennas more or less whitish above, brownish beneath, 

 basal third brownish above and below; mandibles with brown margins, claws 

 brown, tarsi brownish.

Phygadeuon (Pezoporus?) fungor Norton. 



This species has previously been placed in the Ichneumonicse, Pbseogenes, 

 but it has a distinct cryptine groove. Two specimens have the scutellum and 

 dorsulum entirely black, as in the type from New York state; in the third epeci-
