28 NOTES ON CHALCIDIiE. 



C. Hind femora without spines and not serrated. 



a. Radius of the fore wings as long as, or 



longer than, the ulua; cubitus with a 



thick knob. .... Megastigmus. 



b. Radius much shorter thau the ulna; cubitus 



with no thick knob. 

 * Scutellum near the tip with a strongly im- 

 pressed transverse line. - - Stntomaspis. 

 ** Scutellum with no strongly impressed trans- 

 verse line. 

 f Sutures of the parapsides coming close to 



the scutellum. ... Lochctes. 



If Sutures of the parapsides at some distance 



from the scutellum. ... Callimome. 



Podagrion is found in most parts of the world, and is represented 

 by a few species, which feed on the eggs of the Mantis tribe. 



Palmon pachymems is a synonym of Podagrion splendens ; the 

 latter genus and Bachyrischion, Costa, are identical. 



Torymus (Cryptopristus, Foerster) includes the following species : — 

 caliginosus, calcaratus, laticornis, macromerus, intermedius, fulvo- 

 cinctus and Syrphi. T. calcaratus is associated with Megastigmus 

 giganteus in the single-chambered Mediterranean oak-gall. 



Monodontomerus is represented by M. dentipes, Anthophorae, inter- 

 medius, militaris and vacillans, and is a parasite of bees ; it also 

 includes M. Phormio, a South-American species. 



Diomorus has two species, nobilis and Kollari ; it can hardly 

 include Torymus tarsatus, Nees, and T. dubius, Nees, which have a 

 depressed abdomen. 



Oligosthenus is founded on O. stigma, 0. ater and 0. tibialis. 

 O. stigma is exclusively attached to the large pincushion-rose-gall, 

 where, in conjunction with Callimome bedeguaris and a species of 

 Porizon, it limits the increase of Rhodites Rosae. 



L. Papaveris is the only species known of Lochites. 



Syntomaspis is closely allied to Callimome, and is represented by 

 chrysis, euryuotus, lazulinus, macrurus. 



Megastigmus contains a few European species, a few in Australia 

 of small size, and two rather large Californian species, M. Pinus and 

 M. albifrons. 



Torymus erythrothorax, Nees, is perhaps a synonym of M. collaris, 

 Boh., and of M. strobilobius, Ratz. Tbe oviduct of M. Bohemanni 

 Rate., reaches to the scutellum, and that of M. brevicaudis, Ratz., is 

 hardly as long as the abdomen. 



The species of Callimome are very numerous, and appear to be 

 exclusively in attendance on galls. Tbeir colour is golden green,
