men the scutellum is largely rufous and the dorsulum has a broad brownish 

 stripe down the middle. 



Three males from Douglas county, Kansas, 900 feet. June and July, 1892,

Ichneumon? (Stiboscopus?) oryxicornis, n. sp. 



Related to Ichneumon? honestus Cresson. 



Male. — Length, 11 mm. Head shining, the cheeks especially; face closely 

 punctured, space between clypeus and antennas moderately elevated; clypeus 

 not separated posteriorly by a groove, the anterior margin entire, straight; malar 

 space less than half the width of the mandibles at base; front punctured very 

 much like the face; vertex and cheeks similarly punctured, the punctures dis- 

 tinctly more separated than on the face; ocelli almost forming an equilateral tri- 

 angle, distance between the posterior ocelli distinctly greater than the distance 

 between lateral ocellus and nearest eye margin; antennge thirty-five jointed, 

 scape and pedicellum together about as long as the first joint of the flagellum or 

 a little shorter. Thorax almost uniformly shining, the dorsulum alone some- 

 what dullish; dorsulum with distinct, well-separated punctures and parapsidal 

 grooves, the parapsidal grooves moderately impressed and present only on the 

 anterior third of the sclerite; scutellum convex, sparsely punctured, and not 

 margined laterally; poetscutellum apparently impunctate; superior face of 

 metathorax with the basal area nearly crowded out and not defined laterally, 

 and with an areola that is little more than a semicircle, posterior face with three 

 areas; the petiolarea central, as wide as the areola, nearly parallel sided and 

 broadly, shallowly channeled, the spiracles occupying the upper portion of the 

 lateral area, near the metanotal-metapleural suture very narrow and long, di- 

 rected obliquely backward and outward; mesopleura with distinct, closely ar- 

 ranged punctures and a transverse impression across the middle of the posterior 

 half of the sclerite, the impression joining the posterior margin in a kind of pit, 

 the cryptine groove appears as a crenulate, impressed, narrow groove on the ante- 

 rior half of the mesosternum, close to and parallel with the junction between the 

 mesopleuron and mesosternum; metapleura more closely, regularly punctured 

 than the mesopleura; wings tinted rather moderately with brown, the nervures 

 dark brown, stigma pale brown; areolet pentagonal, nearly quadrangular, dis- 

 tinctly longer than the greatest width, the radial side of the areolet about as 

 long as the pedicellum is high and a little less than half the length of a trans- 

 verse cubitus, the first cubital side longer than the second which is a little more 

 than half the length of a transverse cubitus, discocubital nervure with a faint 

 trace of a stump of a vein near the middle, the transverse median nervure inter- 

 stitial, in the posterior wings the transverse median nervure is broken distinctly 

 below the middle, a little below the junction of the lower third with the middle 

 third. Abdomen dullish, except the petiole which is shining; sides of the petiole 

 with a groove bounded above by a ridge that is interrupted at the spiracles and 

 continues a little beyond the spiracles to the posterior margin ; the second seg- 

 ment polished at base and distinctly, sparsely punctured, remainder closely 

 punctured; succeeding segments closely, more or less distinctly punctured. 

 Covered with inconspicuous short pubescence which is to a great extent whitish, 

 tinted with golden on the dorsulum. Black; more or lese broad orbital line, all 

 of face below antennte. mandibles, except apical portion, superior border of 

 propleura and a transverse line below insertion of wings lemon yellow; antennae 

 brown below, black above, except joints 15, 16, 17, 18, 19, 20, which are more or 

 less cream color; palpi whitish; inferior margin of propleura, tegula?, oblique 

 line and spot on lower half of mesopleura, a large part of anterior and middle
