18 THE ENTOMOLOGIST. 



ihan t« ice 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 ; tibiae 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. Antennae tawny; first joint pale 

 luteous. Oviduct pale luteous; sheaths black. Wings pel- 

 lucid ; veins pale yellow. Length of the body \\ 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 Micranisa, Walker. 



Body rather slender. Head and thorax very finely 

 squamous. Head transverse, broader than the thorax. Eyes 

 very large and prominent. Trophi very small. Antennae 

 10- or 11-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 tibiae 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. Antennae tawny. Sheaths 

 of the oviduct black. Legs luteous; hind femora green. 

 Wings pelkicid ; veins pale yellow. Length of the body 

 1 line. One specimen. 



The short ovipositor of this genus shows that it is not 

 parasitic on larvae that feed within the fig.
