A remarkable genus which does not fit well into any of the families of parasitic 

 Hymenoptera. In having the abdomen inserted well upon the thorax it agrees with 

 the " Evaniidae," but differs from them in other respects. It forms a connecting link 

 between the Braconidae and Evaniidae. Species are known from the Malay Archipelago, 

 Cuba, South America, and Europe.

Antennae filiform, of nearly equal thickness throughout, longer than the body. Head 

 shining, the face punctured. Thorax : mesonotum shining, rugose in front and laterally, 

 the pleura? shining and impunctate ; metathorax rugose, and covered with long pale 

 hair, the pleurae and sternum also covered with hair. Abdomen twice the length of the 

 thorax, narrow, linear.

Hal. Panama, Bugaba 800 to 1500 feet (Champion). 



Antennae about as long as the body, the flagellum microscopically pilose, the apex 

 brownish. Head shining, the face semiopaque ; closely and rather strongly, the sides 

 to the vertex more irregularly and widely, punctured ; frontal depression shining ; the 

 oral region laterally and the space below the antennae rufous ; the face (especially on 

 the lower part) sparsely covered with pale hairs, the upper and hinder parts with 

 blackish hair. Pronotum, mesonotum, and scutellum shining, sparsely, indistinctly 

 punctured ; the sutures broad, strongly crenulated ; mesopleurae and sternum almost
