the lower one. Antenne 68-jointed, slender, longer than the body, the 
flagellar joints all about twice as long as thick; the first three times; 
scape oval, twice as long as thick. Prothorax smooth and shining, 
deeply impressed across each side. Mesonotum smooth, strongly 
elevated, especially the middle lobe in front; the parapsidal furrows not 
sharp, but more or less indicated in front by broad impressions. Scutel- 
lum triangular, margined only at the sides of the basal impression; its 
disc with a few large punctures. Metanotum smooth medially in 
front, on the sides punctate and behind irregularly rugose. Pleurz 
smooth, with a few punctures only on the metapleure. Abdomen 
highly polished, smooth beyond the base of the third segment. Legs 
long and thickly hairy on the tibie and tarsi. Wings deeply infuscated, 
nearly black, but with very little violaceous reflection; veins black, 
piceous beyond the cross-veins. 
One male. Para, Brazil. Mr. Wm. M. Mann. 
This is a very conspicuous species on account of its brightly 
contrasting thorax, black wings and polished body. 
Subfamily SPATHIINE 
Heterospilus fasciiventris sp. nov. 
Female. Length 2.2 mm.; ovipositor 0.7 mm. Meso- and meta 
thorax, first segment and posterior third of second segment of abdomen 
black; head dilute piceous, black above. Scape, base of antenne, 
ovipositor and legs pale yellow. Abdomen, except for the black mark- 
ings, pale honey-yellow. Extreme tips of tarsi and ovipositor black. 
Head twice as broad as thick, moderately narrowed behind the eyes 
and somewhat excavated behind; strongly margined behind. Vertex 
shining; feebly, but distinctly transversely aciculate; with a circular 
impression to the side of each posterior ocellus, the two narrowly con- 
nected above the ocell1; posterior ocelli nearly as far from each other as 
from the eye margin; front slightly concave, weakly transversely 
aciculate, the lateral margin slightly carinate just above the antenne. 
Antenne long and slender, basal flagellar joint six times as long as thick; 
the joints near the middle of the flagellum four times as long as thick. 
Face honey-yellow, rugulose, clypeus honey-yellow, very convex. 
Mesonotum shagreened, with deep, convergent crenulate parapsidal 
furrows; middle lobe aciculate behind as in the following species. Scutel- 
lum shagreened, with a broad, deep longitudinally fluted groove across 
its base. Metathorax partly areolated; its upper face with a lateral 
carina, and the sides of a posterior carina, enclosing a large rugulose 
area which 1s angularly excavated behind by a large diamond-shaped 
supero-median area that is open behind at the apex of the metathorax 
and closed near the base; surface except on the basal area coarsely 
rugose-reticulate. Pro- and mesopleure shagreened, the former with 
a deep, oblique groove, the latter with a deep groove along its lower 
margin, several oblique foveate impressions at its anterior angle and 
with a crenate line along its posterior edge. Metanotum rugose- 
reticulate, with a minute thorn-like projection just above the middle
