Subfamily III. Monodontomerin.'e. 

 1875. Toryrnides, Subtribus (partim) Thomson, Skancl. Hym., IV., p. 59. 

 1899. Monodontomerinse, Subfamily III., Ashm .Proc. Ent. Soc. Wash., IV., p. 247. 



In this group the hind femora are more swollen than in the previous groups, 

 while the lower edge is serrate or armed with one or two teeth, thus showing an 

 approach to the Podagrioninie, and through tliat subfamily to the Leucospidinic and 

 the Cludcidinse. 



Some of the species are parasitic upon hymenopterous and dipterous gall-mak- 

 ing insects; other.s, belonging to the genera Physothorax and Plesiostigma, have been 

 bred from fig-insects, while species belonging to the genera Diamorus and Monodon- 

 tomcrus are bred commonly from the nests of bees and wasps, and they are said to 

 be parasites of these insects. In a single case, at least, I have positive evidence that 

 Monodontomems was bred from the puparium of a tachinid-fly found in the nest 

 with the bee.
