184 E. T. CRESSON. 



sanguineous, incisures deeply impressed ; first segment yellow medially, disc 

 prominent and convex, a broad shallow depression on each side, with a longi- 

 tudinal carina between the median prominence and the lateral margin; second 

 segment very large, with a small triangular prominence on basal middle, on 

 each side of which is a large, broad, deeply impressed fovea, and a transverse, 

 deeply impressed line across the middle of the segment, broad on the disc and 

 furcate laterally; ovipositor longer than abdomen. Length .40 inch. 

 Two specimens. (Belfrage.) 



Bracoii riigiceps, n. sp. 



9. — Differs from epicus as follows: — Head smaller, less full behind the 

 eyes ; face opaque and coarsely rugose; scape simple ; a honey-yellow spot be- 

 neath each eye ; the disc of median prominence on first abdominal segment 

 with two elongate fovese ; the second segment has a flat rhomboidal promi- 

 nence on basal middle, the tip of which is carinate and prolonged posteriorly 

 nearly to the middle of the segment, with a deep fovea on each side and a deep 

 oblique line on each side of basal middle, ending in a deep fovea near lateral 

 margin; the transverse median line is furcate as in epicus. Length .40 inch. 

 Cue specimen. (Coll. Gr. W. Belfrage.) 



^ Bra<^on simplex, n. sp. 



9. — Black, smooth and polished; head very full behind the eyes; face 

 with a median tubercle below antennse and two deep foveje above clypeus, and 

 between them two longitudinal depressions, the two tubercles at base of an- 

 tennae very prominent and tinged with reddish, and the lateral carinse between 

 base of antennse and eyes also very prominent; excavations of vertex very 

 deep and separated by a sharp carina; upper anterior orbits and middle of 

 mandibles reddish; scape elongate-quadrate, both base and apex reflexed ; disc 

 of metathorax tinged with reddish; wings as in ejotcMS, except that they are 

 paler at tip, and the second cubital cell rather longer, with its basal nervure 

 more oblique; legs black, sericeous with pale hairs, apex of trochanters be- 

 neath sanguineous ; abdomen oblong-ovate, much narrower and more de- 

 pressed than that of e/)icMS, shining, pale sanguineous; first segment with a 

 deep longitudinal groove near lateral margin, the disc subconvex, orange-yel- 

 low, margined and carinate laterally; second segment with a large cuneiform 

 prominence on basal middle, the tip accuminate and prolonged posteriorly 

 nearly to the transverse groove, with a profound depression on each side, me- 

 dian transverse line very deep, subcrenulate and simple — not being forked 

 laterally, on each side near base a broad irregular shallow depression, and a 

 small lateral fovea behind the transverse groove; remaining segments smooth 

 and even, not incised, the terminal segment with a broad shallow depression ; 

 ovipositor as long as body. Length .45 inch. 



One specimen from Comal Co. Very distinct from the two preced- 

 ing species by the sculpture of the head and abdomen. 



-f Bracon orbitalis, n. sp. 



% 9 • — Black, smooth and shining ; head not unusually full behind the 

 eyes; face smooth, with an arcuated depressed line above orifice which is com- 

 pletely circular, vertex scarcely excavated; middle of mandibles reddish; or- 

 bits more or less reddish-yellow, dilated into a spot on each side of antennas
