to the latter as a pair of raised lines. Scutellum with a pair of large 
. quadrate depressions at the base separated by a fine median raised line. 
Mesopleura elevated along its upper edge and near the upper anterior 
angles, and with an oblique impressed groove (larger behind) below. 
Metathorax as described in the generic diagnosis, its lateral angles 
slightly toothed. Abdomen as long as the head and thorax together; 
first segment but little widened apically, the central raised portion 
bordered by lateral carinz and with a pair of converging carinz on its 
disk, on the sides with a carina above the lateral margin; its surface 
coarsely aciculate except at the base of the median lobe. Second 
segment with a pair of approximate rounded elevations behind and with 
a deep moderately oblique groove from each anterior angle which 
defines a triangular lateral piece. Third segment tuberculate, raised in 
front on each side of the middle and also at the anterior and posterior 
angles; following segments smooth. Legs stout; fore tarsi twice as long 
as their tibize; hind femora much thickened, less than four times as long 
as broad. Wings with lanceolate stigma which is black before the 
origin of the radius, and pale brown beyond; veins dilute fuscous, 
piceous under the black markings; submedian cell longer than the 
median by one-third the length of the transverse iredian vein; recurrent 
nervure received at the apical sixth of the first cubital cell; discoidal 
nervure arising at the posterior angle of the second discoidal cell. Hind 
wing with the submedian cell two-thirds as long as the median; the 
resurrent nervure distinct.

Mr. Mann obtained a female of this species at Baixa 
Verde, Rio Grande do Norte. It agrees well with Brullé’s 
description, except that it is a trifle smaller (12 mm. ovip. 6.5 
mm.) and the vertex is rufous like the rest of the body. 
Bracon paraensis sp. nov. 
Female. Length 4.5 mm., ovipositor 1.4 mm. MHoney-yellow 
marked with black, paler on the lower parts of the head and abdomen 
below. The following parts are black: antenne; broad bands on the 
second, third, fourth and fifth segments, all of equal length and crossing 
the fifth segment completely but leaving broad pale lateral spaces on the 
more anterior segments; sixth segment entirely; ovipositor sheaths, 
apical joint of four fore tarsi; and hind legs beyond the trochanters, 
although with the knees and tarsal articulations yellowish. Wings 
deeply infuscated, more strongly so at the base. Head two and one- 
half times as broad as thick, rapidly narrowed behind the eyes and not 
excavated behind. Vertex smooth, ocelli equidistant, separated from 
one another by their own diameter. Front shagreened medially, with 
a central finely impressed line above the antenne to the ocelli. Antennz
