1912] Brazilian Ichneumonide and Braconide 195 
one-third the length of the basal nervure; discoidal vein arising at the 
lower third of the second discoidal cell; transverse median vein of hind 
wing broken almost at its extreme apex. 
One male collected by Mann and Baker, at Kete Purange, 
near Manaos, Brazil. 
This species is related to J. annulata Brullé from Guiana 
from which it differs in structure and slightly in color, although 
of quite similar color-pattern. 
Subfamily CRYPTINE 
Megaplectes branneri sp. nov. 
Male. Length 16 mm. Ferruginous, the head and anterior part 
of the thorax black with yellowish white markings. The entire face 
and mouthparts are pale, as well as the inner orbits above the antenna, 
those behind the upper part of the eye, and the cheeks. The prothorax 
is also lined above and below, the mesopleura at its anterior upper angle, 
the scutellum on its sides and behind, and the whole postscutellum and 
the tegule pale. Antennze black, with broad whitish annulus near the 
apex. Legs pale yellow, the four posterior ones ferruginous to the tips 
of the femora. Fore femora along the lower edge, last two joints of 
fore tarsi, a streak apically below on the middle femur, the middle 
tibial spurs, last three tarsal joints; second trochanter of hind leg, tip of 
femur, inner side of tibia and its spurs piceous or black. Wings pale 
ferruginous, stigma and veins black. Head smooth, impunctate, face 
with a longitudinal depression each side of the median line terminated 
below by the large clypeal foveze; anterior edge of clypeus truncate, 
very faintly produced at the middle. Antennz about as long as the 
body, slender and tapering, the first joint of the flagellum four times as 
long as thick, following decreasing in length; those toward the middle 
of the flagellum twice as long as thick; all except a few basal joints 
slightly nodosely thickened near their tips as in certain genera of Jop- 
pini although not so distinctly. Maxillary palpi with the second joint 
triangularly enlarged, the fifth joint very slender, nearly as long as the 
two preceding; labial palpi simple. Mesonotum finely, confluently 
punctate, without parapsidal furrows; scutellum more coarsely and 
sparsely punctate. Metathorax armed with a pair of unusually large 
and stout erect lateral spines; incompletely areolated; pleural carinz 
complete, very strongly and evenly curved; basal pleural areas complete, 
sparsely punctate; basal median one smooth medially; hexagonal in 
position, but open behind, as its sides are prolonged as parallel carine 
the entire length of the metanotum; surface behind the areas trans- 
versely rugose, most roughly so behind the lateral spines. All pleure 
shining, more or less punctulate. Metathoracic spiracles elongate, 
four times as long as broad. Mesoépisternal groove distinct only in 
front. Abdominal petiole smooth and shining, with a very few scattered 
punctures on the sides of the post-petiole. Second segment with deep 
gastrocceli, smooth at the very base; densely finely punctate elsewhere; 
third segment similarly punctate except at tip; following segments
