A New Genus of Chalcidoid Hym 
A. A. GERAULT 
Tribe ISOPLATINI 
Coelocybella new genus 
Female :—Head normal, rounded, the vertex broad, the lateral 
ocelli distant from the eye margin, the antennz inserted near the 
middle of the face, slenderly clavate, 13-jointed with three ring- 
joints, five funicle joints and three club joints, all these joints 
wider than long excepting the conical distal joint of the club. 
Pedicel long obconic, as long as the four joints following (the 
ring joints and the proximal funicle joint), half as long as the 
cylindrical scape. Occipital margin obtuse; prothorax conical, 
short; mesoseutum with complete, distinct parapsidal furrows, 
secutum slightly longer than the ungrooved secutellum. Propo- 
deum with a very weak median carina, the spiracles moderate in 
size, round, no lateral carine nor sulci. Abdomen sessile, broad 
oval, depressed, about as long as the thorax, the second segment 
about a third of its length, the ovipositor not exserted, the abdo- 
men from dorsal aspect ovate, widest about the middle, wider 
than the thorax. Submarginal vein unbroken, at least two and 
a half times longer than the marginal, the latter nearly twice the 
length of either the stigmal or post-marginal, both of which, for 
them, are moderately long, the stigmal vein with a rather large 
rounded knob and a distinct neck which is as long as the diameter 
of the knob. Discal cilia dense and fine, the marginal very short. 
Tarsi five-jointed, the tibial spurs single, the intermediate longer, 
one very long, the posterior one short, stout. Non-metallic, 
marked with yellow, the wings hyaline. Abdomen wider than the 
head or thorax. Axillae separated by a short distance. Mandibles 
bidentate, the inner or second tooth truncate, unequal in the two 
mandibles. 
Male :—Not known. 
Because of the venation, this genus will not be confused with 
the Tetracampini but its five-jointed tarsi make it unique for the
