THE ENTOMOLOGIST. 17 
length of the humerus; cubitus curved, much shorter than 
the ulna; no stigma; radius rudimentary. 
AGRIANISA MYRMECOIDES. 
Luteous; wings pellucid; veins luteous. Length of the 
body 2—3 lines. Four specimens. 
This genus differs much in structure from Agaon, Blasto- 
phaga, and Sycophaga, the other described genera of the 
family. It has some resemblance to the genus Bethyllus, and 
to the Formicide. 
IDARNES ORIENTALIS, Walker. 
Female.—Metallic-green, slender. Head and thorax very 
finely squamous. Head transverse; face perpendicular. 
Trophi small. Antenne inserted in the middle of the front, 
10-jointed, piceous, clavate, nearly as long as the thorax ; 
first joint pale yellow, long, slender; second cyathiform ; 
third to seventh transverse; club fusiform, a little broader 
than the seventh joint, and full twice its length. Thorax not 
much developed. Prothorax and metathorax less developed 
than the mesothorax. Abdomen smooth, lanceolate, much 
longer than the thorax, pale yellow beneath towards the 
base. Oviduct tawny, about thrice the length of the body, 
slightly incrassated at the tip, which is black. Legs slender, 
pale yellow; tarsi 5-jointed. Wings pellucid. Fore wings 
narrow; veins pale luteous; ulna more than half the length 
of the humerus; radius a little longer than the ulna; cubitus 
extremely short. Length of the body $ line. Two specimens. 
The genus Idarnes hardly belongs to the Agaonide. The 
only species hitherto described is a native of the West Indies. 
The long ovipositor indicates that it is parasitic on larve that 
feed quite in the interior of the fig. 
Genus Porantsa, Walker. 
Female.—Body slender, smooth. Head oblong. Trophi’ 
small. Antenne 10-jointed(?), inserted near the mouth, 
nearly filiform, much shorter than the thorax ; first joint. long, 
stout; second elongate-cyathiform ; third and ‘following joints 
elongate, linear; club composed of three transverse joints. 
Prothorax very long, nearly flat. Mesothorax short. Meta- 
thorax well developed. Petiole very short. Abdomen more
