Group 1 



This group ^ is distiuguished by the following characters: (1) small 

 size, (2) very dark stigma, (3) punctation usually very crowded, (4) 

 anterior abdominal segments and propodeum often more or less red- 

 dish, (5) mandibles of female with two denticles, (6) mesosternal 

 tubercle on the female, (7) small and widely separated hair lobes on 

 the male, (8) apical segment of the antennae normal in the male. 



8 This group is the one Banks (1947, p. 26) calls Apiraptrix (Shestakov). 

 Banks misspelled this "Apiratrix." In a personal letter, de Beaumont informs 

 the present writer that this group is not Apiraptrix (Shestakov). The latter is 

 related to C. rybyensis (Linnaeus) Schletterer.
