New Chalcidoid Genera and Species from Paraguay. 173 
of tibiae (excepting centrally, exteriorly) which are deep fuscous. 
Tip of abdomen black; exserted portion of ovipositor fuscous. 
Antenna black suffused with slight metallic greenness, the first 
funicle joint more so, the scape and pedicel distinetly metallic 
green and blue. N 
Whole body rather densely umbilicately punctate, the 
punctures largest on the scutellum, smallest on the first 
abdominal segment and next so on the vertex. The inter- 
spaces on the abdomen are glabrous but on the thorax each 
puncture is connected with its neighbours by short, radiating, 
narrow sulci or striae around all the margin, giving each puncture 
a puckered appearance. Lateral ocelli distant from the eye margin. 
Head bicornuted in front of the ocelli, the scrobicular cavity 
deep. Scutellum terminating in a rimmed plate whose apex is 
slightly flattened but not emarginate. Acuminate part of ab- 
domen (distad of segment 5) clothed with dense, stiff hairs. Fifth 
abdominal segment longest of the first five (counting the petiole 
as segment 1). Postmarginal vein about three fourths the length 
of the marginal, the stigmal vein rather long but much shorter 
than the postmarginal. Discal ciliation of the fore wing dense, 
Ovipositor exserted for a short distance beyond apex of abdomen. 
Cephalice femora with a bifid tooth beneath near apex. 
Antenna 11-jointed, no ring-joint. The pedicel long, subequal 
in length to the rather long distal club joint, slender, nearly twice 
the length of the proximal funicle joint; second joint of funicle 
longest, the joints after the fourth wider than long, the two proximal 
club joints subequal, neither half as long as the terminal joint; 
joints widening distad; second funiele joint subequal in length to 
the slender pedicel. Pubescence of antennae dense and matted, 
short, dark reddish. 
(From one specimen, the same magnification.) 
Male:— Not known. 
Described from one minutien-mounted female labelled „Para- 
guay (San Bernardino). K. Fiebrig. S. V. II.” 
Habitat: South America—San Bernardino, Paraguay. 
Type: Katalogue No. 31951, Zool. Museum, Berlin, the above 
female, minutien (plus one slide, female antenna). 
2. Epistenia gemmata new species. 
Female:— Length, 7.25 mm. 
The same as the preceding but the abdomen greener and the 
general color darker; the mesoscutum contrasts by being coppery. 
The legs are wholly fuscous or subrufous, excepting the con- 
colorous coxae; the antennae are dark, the scape alone shewing 
very dark metallic green coloration. 
Differs from americana in the following structural characters: 
The plate of the scutellum at apex is more mesial, more truncate
