 men red without blackish infusion; ovipositor pale red, sheaths 

 black, length 3 mm. 



Male. — ^Appears to resemble the female very closely, except that 

 the median ridges of the propodeum converge steadily from behind 

 forward forming an elongate isoceles triangle; while the spiracle is 

 more truly oval than in the female.

 collected by Robertson, the other labeled "Minn.," and from two 

 males, the allotype from "Ks" (Kansas) 2138, coll. C, F. Baker, the 

 remaining paratype from Lexington, Kentucky.

BRACON CALIFORNICUS, new species. 



Large, fossa of mesopleurae crenulate, curved upward, toward the

 67; height of eye, 32; malar space, 30; width between eyes, 37; 

 width at base of beak, 24 ; profile of face very slightly concave to a 

 little below the eyes, then slightly concave on another angle to the 

 apices of the interantennal plates; marginal ridges of antennal pits 

 well developed and extending to the lateral ocelli, most prominent 

 opposite the median ocellus, and nearly obsolete above this; inter- 

 antennal plates fairly well developed; head smooth, shining, sparsely 

 punctured and hairy, the hairs whitish; ocelli arranged in a triangle, 

 the lateral ocelli nearer to the median than to each other, each sur-

 the last which is nearly cylindrical; labial palpi more than half the 

 length of the maxillary palpi. 



Thorax. — Elongated, honey -yellow, propodeum black, caudal half of 

 metapleurae black, dark dull reddish in center, pronotum shining,
