BRUES: PARASITIC HYMENOPTERA. 105 



ovate, the radius originating from just before its middle, its first section two- 

 thirds as long as the second, the two meeting at a very distinct angle; second 

 cubital cell twice as long on the radius as it is high at the apex; recurrent 

 nervure inserted just before the apex of the first cubital cell; median and 

 submedian cells of equal length in both fore and hind wings. 



Seven specimens, type Coll. Amer. Mus. Nat. Hist. A72, others: 

 A31, A35, A128-129, A41; also Nos. 2367-2368, M. C. Z., Florissant, 

 Col. (Nos. 6147 and 8602, S. H. Scudder Coll.). All are well pre- 

 served, and there are several others not so perfect which are probably 

 this species, Nos. 2369-2372 M. C. Z., Florissant, Col. (Nos. 1707, 

 3640, 5032, 6338, S. H. Scudder Coll.). Professor Cockerell's speci- 

 mens are from Stations 14 and 17. 



This is a small species, very similar to the recent Bracon dorsator 

 Say and its allies in general habitus. 



Bracon abstractus, sp. nov. 



Female. Length 8.5 mm. Dark colored, the abdomen lighter, reddish 

 except at the base; legs dark; wings hyaline. Antennae long and slender, 

 with many joints (about 40), very gradually attenuated toward the tips; 

 apical joints small, quadrate; those near the middle about twice as long as 

 thick; basal ones still more elongate, three or more times as long as thick; 

 abdomen as long as the head and thorax together, oval, roughly tuberculate 

 on the basal two or three segments and less plainly so on the apical ones. 

 Ovipositor exserted, but only a short basal part is preserved. Legs stout. 

 Wings hyaline, the stigma and veins strongly colored ; . stigma small, narrowly 

 ovate, very indistinctly angled below, the radius originating at or slightly 

 beyond its middle. Radial cell long and narrow, pointed at the tip, its second 

 section a little more than twice as long as the first; second cubital cell long, 

 nearly twice as long as high at the apex. 



Type.— No. 2373, M. C. Z., Florissant, Col. (No. 9276, S. H. 

 Scudder Coll.). 



This is similar to the preceding species in wing venation, but is 

 much larger and has hyaline wings. 



Bracon resurrectus, sp. nov. (Fig. 87.) 



Female. Length 12 mm. Ovipositor 12.5 mm. Apparently entirely 

 light yellowish, the femora and tibiae of the posterior legs darker and the 

 antennae brownish ; head above and part of the dorsum of the thorax black-
