Hymenopterenfauna von Paraguay. 181 
broadly truncate at the apex. Median segment closely punctured, 
short, steeply sloped posteriorly. Abdomen sparsely punctured, 
tapering slightly at the extremities, longer than the head, thorax 
and median segment combined; the segments feebly constrieted at 
the base. Hypopygium short, blunt at the apex, scarcely extending 
beyond the dorsal segment. Third ceubital cell nearly half as long 
again on the radial nervure as the second. 
Black; a small spot at the base of the mandibles, a minute spot 
on the oceiput, the anterior margin of the pronotum, tegulae, a 
vertical spot on the mesopleurae below the anterior wings, a spot on 
the mesonotum, one on the scutellum, postscutellum, a transverse 
band on each side of dorsal abdominal segments 2—5 broadly 
separated in the middle, and a line beneath the anterior and inter- 
mediate femora near the apex yellow; antennae, tibiae and tarsi 
fuscous. Wings hyaline, nervures fusco-ferruginous, stigma ferruginous. 
Length 9 mm. 
9. Mandibles falcate. Clypeus short, with a longitudinal carina, 
very shallowly emarginate at the apex. Head subrectangular, 
rounded at the posterior angles, broader than long, very finely 
shagreened, with a short frontal suleus ending in a rather large 
frontal puncture, the front produced into a small tubercle on each 
side at the base of the antennae. Thorax finely and sparsely punc- 
tured, the pronotum at least half as broad again as long on the 
anterior margin, slightly narrowed posteriorly, much narrower than 
the head; scutellum much broader than long. Median segment shorter 
than the pronotum, broadened from the base, depressed, with an 
obscure longitudinal carina from the base, sharply truncate posteriorly. 
Abdomen much broader than the thorax, sparsely punctured; the 
apical margin of the first segment slightly raised, with a rather 
broad depressed groove, before it; second segment coarsely rugose 
between two transverse carinae, the apical margin depressed; third 
segment with an impressed transverse line at the base, the apical 
margin of all the segments narrowly depressed. Fifth ventral 
segment coarsely punctured at the apex. Pygidium deflexed, long 
and narrow, fully three times as long as broad, broadly rounded at 
the apex, the sides almost parallel. 
Fuscous, slightly tinged with ferruginous, the apex of the 
abdominal segments narrowly testaceous. 
Length 7 mm.
