18 THE ENTOMOLOGIST. 
than twice the length of the thorax, tapering to nearly half 
its length, compressed and aculeiform from thence to its tip. 
Oviduct longer than the body, emerging from the base of the 
abdomen ; sheaths proceeding from the apex of the abdomen, 
slightly incrassated. Legs moderately long; femora incras- 
sated; tibie slender; tarsi 5-jointed, very long and slender. 
Fore wings narrow; ulna much shorter than the humerus; 
radius and cubitus long. 
PoLANISA LUTEA. 
Female.—Pale luteous. Antenne tawny; first joint pale 
luteous. Oviduct pale luteous; sheaths black. Wings pel- 
lucid; veins pale yellow. . Length of the body 1} line. One 
specimen. 
This genus, with Idarnes and Micranisa, may be said to 
constitute one group, though it differs from them much in 
structure. The form of the abdomen indicates that in the 
act of oviposition the apical half of it is inserted as well as 
the sheaths of the ovipositor. 
Genus Mrcranisa, Walker. 
_ Body rather slender. Head and thorax very finely 
squamous. Head transverse, broader than the thorax. Eyes 
very large and prominent. Trophi very small. Antenne 
10- or 1l-jointed, subclavate, shorter than the thorax. 
Thorax not much developed, much like that of Idarnes. 
Petiole very short. Abdomen smooth, compressed, longer 
than the thorax. Oviduct slightly exserted; sheaths not 
more than one-sixth of the length of the abdomen. Legs 
slender; tarsi 5-jointed; hind femora slightly incrassated ; 
hind tibiz slightly curved. Fore wings narrow; ulna much 
shorter than the humerus; radius more than half the length of 
the ulna; cubitus shorter than the radius ; stigma moderately 
large. Metallic-green, shining. Antenne tawny. Sheaths 
of the oviduct black. Legs luteous; hind femora green. 
Wings pellucid; veins pale yellow. Length of the body 
1 line. One specimen. 
The short ovipositor of this genus shows that it is not 
parasitic on larve that feed within the fig.
