 sternum piceous ; clypeus, trophi, first two joints of antennae, tegulae, and 

 four anterior legs whitish ; abdomen shaped as in Limneria, piceous, 

 nearly black, with sutures i, 2, and 3 pale. 



Head transverse, much wider than thorax, three times as wide as thick 

 antero posteriorly ; eyes large, occupying the whole side of the head; 

 ocelli in a triangle, large, prominent, whitish or pale, the lateral nearer 

 to each other than to the eye; clypeus subtriangularly produced. Thorax

 ible from above ; mesonotum smooth, without furrows ; metathorax short, 

 obliquely declining and delicately areolated. Wings hyaline, iridescent, 

 with the stigma and nervures light brown; stigma narrow, acuminate ; 

 marginal cell narrow, acutely lanceolate, terminating much before the 

 apex of wing; first abscissa of radius straight, forming with the second 

 abscissa a right angle ; cubital nervure interstitial with the first branch 

 of radius, submedian cell a little shorter than the median. Legs long 

 and slender, the hind pair being much longer than the others, their coxae 

 long and cylindrical, and their tarsi thickened the basal joint being as

Types in National Museum. 



Originally described from specimens in Coll. National Museum, 

 labelled No". 124, July 28, " Coll. C. V. Riley," but no record of 

 its habitat or rearing could be found. Since this paper was read, 

 however, among some Hymenoptera sent me by Prof. F. M. 

 Webster for determination, was a single specimen bearing the 

 same number and date, and on writing to Prof. Webster about it 

 he informs me that all the specimens were bred by him at Loftier &% 



Indiana, from an Aphid. 

 This rearing is interesting and virtually substantiates and con- 

 rirms my views in regard to the position the gioup should occupy 

 in the family Braconidce.

 metathorax brown, the latter obsoletely areolated, rest of thorax smooth 

 polished. Wings hyaline, the stigma and venation brown; cubitus in
