1912] Brazilian Ichneumonide and Braconide 225 
coxa. Abdomen as long as the head and thorax together; ovate- 
lanceolate; first segment twice as long as broad at tip, with a somewhat 
raised median space bounded by carine converging from the anterior 
angles, but not very clearly differentiated from the irregular longitud- 
inal aciculations which cover the segment. Second segment nearly as 
long as broad at tip; aciculated on its basal two-thirds; crossed just 
before the middle by a crenulate impressed line, and at its posterior 
third by a broad, shallow groove; third to sixth segments smooth and 
shining. Legs scarcely thickened, sparsely beset with pale hairs. 
Wings subhyaline; stigma and veins dilute fuscous; the former, very 
narrowly triangular, emitting the radius somewhat before the middle; 
first section of radius two-thirds as long as the second; cubitus arising 
a little above the middle of the basal vein; first transverse cubitus 
wanting, second weak, but distinct; submedian cell a little longer than 
the median, the transverse median vein very short, almost punctiform; 
subdiscoidal vein interstitial, the second discoidal cell wide open. 
One female from Ceara-Mirim, Rio Grande do Norte, 
Brazil. (Wm. M. Mann). 
This species is much more slender and structurally quite 
different from the following, and when these small Braconide 
are better known the two will probably fall into different 
genera. 
Heterospilus meridionalis sp. nov. 
Female. Length 2.6 mm.; ovipositor 1.5 mm. Black; apical half 
of antennze and abdomen beyond the second segment piceous; scape 
and base of antennal flagellum castaneous; palpi whitish; coxe pale 
yellow; tegule and legs dull brownish yellow. Wings slightly infus- 
cated, with dark brown stigma and veins. Head shagreened above, 
rugulose on the face; barely twice as wide as thick and sharply narrowed 
behind the eyes; with a strong margin behind. Front concave above 
the antennze, but not deeply impressed; ocelli in a triangle with its 
shortest side above, the posterior ones nearly twice as far from the eye 
as from one another. Face evenly convex, piceous, with a small raised 
smooth spot below the antennz; clypeus dull yellow, semicircular, with 
the arcuate upper margin indicated by a fine raised line. Cheeks 
smooth and polished, malar space about one-third as long as the nearly 
circular eye. Antennz 25-jointed, very slender; scape subcylindrical, 
twice as long as thick; pedicel quadrate; first flagellar joint four times as 
long as thick; following gradually shortening, those near the middle of 
the flagellum three times as broad as thick. Thorax finely shagreened, 
with a faint eneous tinge; parapsidal furrows deep and crenulate; 
middle lobe of mesonotum with three short, deep longitudinal grooves 
before the base of the scutellum. Scutellum with a broad, deep, 
longitudinally fluted groove across its base. Metathorax rugose- 
reticulate, with a rather ill-defined area on each side at the base; these 
areas much more finely sculptured except around the border. Propleurze
