Subfamily II L Monodontomerin^. 

 1875. Toryrnides, Subtribiis (partim) Thomson, Skand. Hym., IV., p. 59. 

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



In this group the liind 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 Podagrioninm, and through that subfamily to the Leucospidi7is3 and 

 the Chalcidinse. 



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

 ing insects ; others, belonghig to the genera Physothorax and Plesiostigma, have been 

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

 tomerus 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 

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

 with the bee.
