which marks off a large squarish space at each lateral angle, and with a 
lateral carina which passes just outside the round spiracle. Meso- 
pleura with a carina along its posterior edge. Abdomen sessile, as long 
as the head and thorax. First segment with a L-shaped shining elevated 
portion; the latter swollen anteriorly and widened laterally along the 
margin of the segment; remainder of the segment paler, whitish; second 
segment twice as broad as long, longitudinally striated, also pale; 
following segments shining and smooth, fully colored. Ovipositor 
ferruginous, its sheaths broad, pilose, piceous with pale yellow bases. 
Legs moderately stout, blackened on the tips of the tarsi. Wings with 
broad stigma that is produced apically into a long, narrow point; 
marginal cell entirely wanting; submedian cell longer than the median 
by the length of the transverse median vein; recurrent nervure received 
at the apical fourth of the first cubital cell; second cubital wanting, 
except for a short stump of a vein that indicates its lower basal corner; 
subdiscoidal vein wanting. Hind wing with only the median and 
submedian cells, the latter less than half as long as the former. 
One female, Ceara-Mirim, Rio Grande do Norte, Brazil 
(W. M. Mann). 
This is possibly not congeneric with the type of Mirax on 
account of its parapsidal furrows, although otherwise similar. 
Subfamily CHELONINE 
Chelonus brasiliensis sp. nov. 
Female. Length 3 mm. Black; the antennal scape, mandibles, 
anterior legs, including most of their coxee; trochanters, tip of femora 
and basal half of hind tarsi dull fulvous-yellow; palpi, tegulee and four 
posterior tarsi whitish yellow. Wings subhyaline; stigma’ black; veins 
piceous, lighter brown toward the base of the wing. Head transverse, 
twice as broad as thick, and very short behind the eyes; finely conflu- 
ently punctate on the vertex, transversely rugulose on the front and 
face; head behind and cheeks smooth, scarcely punctulate. Eyes oval, 
thickly clothed with pale pubescence, nearly twice as long as broad; 
malar space half the width of the eye. Ocelli in a small triangle, the 
posterior ones closer to one another than to the eye margin. Antenne 
in a deep depression; 19-jointed, the scape subcylindrical, curved, as 
long as the first two flagellar joints together; first flagellar joint nearly 
three times as long as thick, the following becoming gradually shorter 
and thinner, the subapical one quadrate. Clypeus separated from the 
face by a sharp suture, with a foveate puncture near each side; arcuately 
rounded on its anterior margin; palpi normal, pale yellowish. Mesono- 
tum and scutellum rugose-punctate, the parapsidal furrows and a 
scutellar margin more or less distinctly indicated by a series of larger, 
more regular punctate impressions. Scutellum, aside from its basal 
strip, nearly triangular. The basal strip sculptured across its entire 
extent by a series of large squarish foveate impressions. Metanotum 
short, declivous, rugose reticulate with several somewhat irregular 
areas behind. Abdominal carapace oval, rather coarsely rugose anter-
