Description. — Antennal scape long, either attaining level of pos- 

 terior ocelli or markedly exceeding it; left mandible with either two 

 or three teeth, right mandible always with three teeth; body shal- 

 lowly and irregularly pitted, dorsum of thorax often partly glabrous; 

 pubescence conspicuously long, white; metafemora relatively slender 

 (fig. 12, Z-6>), outer ventral margin with numerous, minute teeth, 

 basal one always slightly longer than following ones; petiole long, 

 slender, varying from 8 times as long as wide to 15 times as long as 

 wide, length of petiole always three-fourths or more length of meta- 

 coxa, often as long as metacoxa; petiole occasionally enlarged just 

 caudad of the middle (fig. 13, A) ; basal lamina of petiole usually 

 wide, always directed caudad on ventral side. 



The species of Ceratosmicra are, where known, hyperparasites ; 

 they usually emerge from the cocoons of Afcmteles or Meteorus. 



KEY TO SPECIES OF CERATOSMICRA 



1. A Strong tooth projecting from venter of propodeum between 



bases of metacoxae ; petiole 14 or more times as long as wide 



at its widest point debilis (p. 344) 



Propodeum without a ventral tooth; petiole shorter 2 



2. Petiole enlarged between base and apex (fig. 18, h) ; length of 



petiole 8 to 9 times its maximum width meteori (p. 346) 



Petiole not enlarged between base and apex; more than 11 



times as long as wide 3 



3. Flange at base of petiole broader on dorsal than on ventral side ; 



propodeum with lateral teeth paya (p. 348) 



Flange at base of petiole wider on ventral than on dorsal side; 

 propodeum entirely without lateral teeth immaculata (p. 350)
