1912] Brazilian Ichneumonide and Braconide 217 
and rounded basally, separated from the lateral carine by a broad, 
smooth groove. Second segment four times as broad as long, the 
median field narrow, much attenuated behind. Third segment without 
median line or carina, the lateral angles separated by deep grooves; 
barely longer than the second medially and much shorter laterally, 
excluding the produced lateral angles. Third and fourth segments 
each divided by a transverse groove, the third with the lateral angles 
separated. Ovipositor fuscous, its sheaths black. Wings with the 
venation fuscous basally, black at the middle, and pale brown on the 
hyaline apical portion; second cubital cell half as long as the marginal, 
nearly one half longer below than above; recurrent nervure received 
almost at the apex of the first cubital cell, parallel with the first trans- 
verse cubitus. 
One female from Abunda, Rio Madeira, Brazil, Mann and 
Baker. 
This is a stout, heavy-set species with quite conspicuously 
pilose shining body and densely hairy legs. 
It resembles most closely two neotropical species, J. tristis 
and I. semialbus recently described by Szépligeti (Termes. 
Fuzetek., Vol. 24, p. 397, (1901) ), but may be easily distin- 
guished from the first by the form of the first abdominal seg- 
ment and the wing pattern, and from the second by the absence 
of a carina on the third segment and the different color of the 
wings. It isa very striking form, reminding one of a Reduviid 
bug in shape. 
Iphiaulax fortis sp. nov. 
Female. Length 12 mm., ovipositor 9 mm. Black, palpi pale; 
first four abdominal segments and base of the fifth ferruginous; coxz 
and femora, except base of four anterior ones, hind tarsi, and hind 
tibiz except bare inner edge, black; remainder of legs honey-yellow, 
except upper side of trochanters. Wings pale brownish-yellow, infus- 
cated at tips. A rather slender species, with the abdomen elongate, 
the head distinctly broader than thick and rounded off behind the eyes. 
Face confluently punctate, with the median depression between the low 
antennal tubercles extending down to the finely punctate, margined 
clypeus. Eyes oval, four times as long as the malar space. Antennz 
slightly longer than the body; scape twice as long as thick; first flagellar 
joint distinctly longer than the second; following about quadrate. 
Parapsidal furrows distinct anteriorly; scutellum with a line of square 
punctures across its base. Metanotum punctulate on the sides, thinly 
clothed with thin pale hairs, the lateral groove nearly divided by the 
oval spiracle. Abdomen sparsely and coarsely punctate except at base 
and apex. First abdominal segment with its median elevated portion 
somewhat narrowed and rounded anteriorly, but little narrowed behind, 
separated from the lateral carina by a coarsely crenulate groove; the 
segment about as long as broad behind. Second segment rugose-
