1912] Brazilian Ichneumonide and Braconide 207 
iorly; very finely so posteriorly; rounded behind. The apical opening 
oval twice as broad as high. Pleurz rugose-reticulate, more coarsely 
so behind. Legs very stout, especially the hind pair. Stigma broadly 
oval, over half as broad as long, emitting the radius just beyond its 
middle; parastigma distinct, fuscous. Radial cell short, the postmar- 
ginal vein no longer than the stigma; length of first, second and third 
sections of the radial vein in the proportions of 2,3 and 7. Submedian 
cell longer than the median by the length of the first section of the 
radius; recurrent nervure interstitial with the first transverse cubitus 
which it equals in length; discoidal vein broken near its lower end. 
Natal, Brazil. One specimen collected by Mr. W. M. Mann. 
This is the first South American species to be described. 
There are two other specimens, somewhat smaller and with 
darker legs, from Independencia, which may possibly represent 
another species, but structurally, there are only slight differences.

wing; spot before tip of all femora; anterior and middle tibiz, except 
base; extreme base and apical third of posterior tibia. Wings yellowish 
at base with yellow veins and stigma; apically subhyaline, with fuscous 
veins, stigma slightly mottled with fuscous. Head one half broader 
than thick, arcuately rounded behind the prominent eyes; vertex finely 
rugose, the ocelli close together, the hind ones five times as far from the 
eye as from one another. Front just above the antenne with a mar- 
gined depression which includes the anterior ocellus and bears a fine 
raised median line that extends halfway down the face; face finely 
rugose. Antenne: 23-jointed, tapering; as long as the body; scape 
almost cylindrical, as long as the first flagellar joint which is four times 
as long as thick; following gradually growing shorter, at middle of anten- 
na three times as long as thick. Eyes bare, cheeks with an indistinct 
malar groove half as long as the diameter of the eye. Head behind

parapsidal furrows. Scutellum triangular, longitudinally rugulose, 
the thoracic dorsum longitudinally striated on each side of the scutel- 
lum. Metanotum rugulose, exareolated, the upper hind angles pro- 
duced into short blunt teeth. Abdomen as long as the thorax; three 
segmented, the third segment longest; first a little shorter and second
