tapering out on the sides; venter shining, more thickly punctured 

 and hairy than the pleurae; metanotum with a small, transverse, 

 almost triangular arched plate in its middle, followed by a very short 

 longitudinal ridge; metapleurae strongly crenulate around the borders, 

 except in front, with a prominent ridge above the msertion of the 

 hind coxae, this ridge meeting the outside ridge of the propodeum 

 above to form a blunt tooth; most of the surface of the metapleurae 

 shining and sparsely punctured and hairy, the lower border duller 

 and coarsely rugose; propodeum in profile nearly horizontal above, 

 the hinder face very sharply declivious, almost vertical, the two faces 

 forming almost a right angle, coarsely areolate, with three well- 

 defined longitudinal ridges on each side, the two median forming an 

 elongate isoceles triangle with its apex pointing forward, and with 

 about 7 transverse ridges between the two; the spaces between the 

 first and second and the second and third ridges on each side coarsely 

 and more or less regularly wrinkled; spiracles elliptical, almost slit- 

 like, the inner side more flattened than the outer. 



Wings.— Length, fore 10.5 mm., hind 8 mm.; very dark fuliginous, 

 with a pale streak behind the costa and another in front of the anal 

 nervure, with a translucent spot immediately below the base of the 

 stigma, another just beyond the branching of the discoidial and the 

 first recurrent nervure, and the usual breaks in the cubital veins; 

 venation typical of the genus. 



Legs. — ^Fore and middle legs black, hind coxae and femora red, 

 hind trochanters red with a blackish tinge, hind tibiae dark, almost 

 black at base, dark red near the middle, and black at apex, hind tarsi 

 black; all tibial spurs lighter at tip; apical segments of fore and 

 middle tarsi lighter, dark reddish-brown; all tarsal claws cleft; middle 

 tibiae without spines on the outer surface near the apex; hind tibiae 

 with two apical spines above the smaller apical spur. 



Abdomen.— Elong&te, shining, red, sometimes irregularly blotched 

 with blackish infusion; length, 5.5 mm.; spiracles of the first abdom- 

 inal segment placed on small tubercles; ovipositor pale red, the 

 sheaths black, length 3 mm. 

 Male. — Not known. 



This species is described from two female specimens, collected at 

 "Biscay Bay, Fla.," presumably by ^Ii-s. A. T. Slosson, as Ashmead 

 has given the specimens the manuscript name used above. These 

 specimens, the type and paratype, Cat. No. 20476, are deposited in 

 the collection of the United States National Museum. 



The species is very distinct, and departs in many ways from the 

 typical Bracon.
