Family Ichneumonid.e. 

 Phygadeuon ( Bathymetis) spinicoxus, n. sp. 



Very conspicuous on account of the spined posterior coxse. 



Female. — Length, G.5 mm. Head shining, somewhat dull; face rather 

 sparsely punctured, elevated between the insertion of the antennje and clypeus; 

 clypeus sparsely punctured, not separated from the face posteriorly by a groove; 

 malar space about as high as half the width of the mandibles at base ; mandibles 

 distinctly bidentate, the lower tooth distinctly shorter than the upper tooth; 

 ocelli forming a low triangle, distance between posterior pair a little greater than 

 the distance between lateral ocellus and nearest eye margin ; front, vertex and 

 cheeks almost uniformly punctured, the punctures thereon well separated; 

 antennae twenty-eight jointed, second joint of the flagellum apparently a little 

 longer than the first, and about as long as the scape or a little shorter. Thorax 

 shining; dorsulum with well-separated punctures, parapsidal grooves present 

 and distinct only on the anterior fourth of the segtnent; ecutellum sparsely 

 punctured, polished; superior face of the metathorax with the basal area prac- 

 tically crowded out and the areola more than a semicircle, posterior with three 

 areas, the petiolarea defined by moderate raised lines, below transversely 

 wrinkled, forming a shallow, broad channel that is as wide as the areola at base 

 and apex and not much wider in the middle, the raised lines or ridges bounding 

 the posterior face nearly produced into sharp angles a little below the middle of 

 the segment, spiracles circular and nearer to the raised line separating the lat- 

 eral areas than to the suture between metanotum and metapleura, connected 

 with the lateral suture by a straight raised line ; metapleura sculptured very 

 much like the mesopleura; posterior coxiv with a strong tooth below near the 

 apical end, pointed inward and backward, posterior femora a little more than 

 three times as long as broad, the posterior tibiaj not much dilated at apex; 

 wings tinted with smoky, the stigma and nervures very dark brown, nearly 

 black: areolet pantangular, the sides nearly of equal length, the discocubital 

 nervure not broken, the transverse median nervure interstitial; the transverse 

 median nervure in the posterior wings broken a little below the junction of the 

 basal with the middle third. Abdomen shining, indistinctly punctured; the 

 second segment with a transverse impressed line in the middle and at base a 

 transverse groove or channel; ridge of the petiole not extending uninterrupted 

 to the apex of the segment. Inconspicuously covered with short, silvery pubes- 

 cence which is longest and most apparent on the metathorax. Ferruginous; 

 sutures of the thorax more or less black; mandibles brown at apex, edge of an- 

 tennal foveas dark brown; antennaj with the first ten joints brownish testaceous, 

 joints 11, 12 and 13 more or less whitish, the joints beyond dark brown; four an- 

 terior legs more or less testaceous. 



Type: University of Kansas. Type locality: Magdalena mountains, New 

 Mexico. August, 1894, F. H. Snow. 



Paniscus geminatus Say. 



Female, with the lateral transverse carinte near apex of metanotum wanting 

 and the transverse strife of the metanotum obsolescent. 



Willow Park, Colo., 7500 to 8000 feet; June, July, 1892, V. L. Keilogg.
