New Chaleidoid Genera and Species from Paraguay. 75 
Family Eulophidae. 
Subfamily Entedoninae. 
Tribe Entedonini. 
Genus Horismenus Walker. 
1. Horismenus macrogaster new species. 
Female:— Length, 2mm., more or less. Moderately large 
for the genus. 
The same as cyaneoviridis Girault but differing in the following 
particulars: The long setigerous fovea at the caudolateral corner 
of the mesoscutellum is replaced by a short, foveate paired groove, 
bearing a very long seta caudad and rather irregular; it extends 
about halfway up the scutellum, and in reality the foveae are 
only the polygonal reticulations deepened; the metathoracie 
spiracle is elliptical, moderately large; the metathorax is distinetly 
roughened, with a scaly punctation, its median carina is smooth 
and metallic, acute, becoming wider and obtuse cephalad; the 
sulci on each side wide, roughened like the surfaces of the meta- 
thorax, bronze in color, acutely margined laterad, the median 
carina branching at right angles from each side before reaching 
the base of the segment, each branch going laterad for a length 
equal to the length of its median part, then at right angles running 
to the base of the segment; it thus forms a broad cross-suleus 
across the dorsal aspect at base; this is roughened like the long- 
itudinal sulei. The rightangled branch of the carina is difficult 
to detect from the direct dorsal aspect; the lateral, carinate margins 
of the sulci from that aspect are convex and are smoother than 
the median carina. Abdominal segments polygonally reticulated, 
the proximal two thirds or less of the long second segment smooth 
and shining, metallic green, its distal third darker like the other 
segments and very minutely punctate, each pin puncture bearing 
a very short minute seta; the hollow concavity at base just distad 
of the short petiole is reticulated. The margins of the polygonal 
reticulations of the thorax are raised lines, the areas not deep 
enough to form real punctures. The pubescence of the eyes is 
moderately long and soft; a few very long setae on the thorax. 
Vertex in the direct dorsal aspect with a subobtuse sulcus at the 
meson between the elliptical lateral ocelli; cephalic ocellus in the 
cephalic aspect or nearly.
