ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 241 



Postmarginal vein not longer than the stigmal ; mandibles very long, falcate, bidentate at apex ; antennae 

 11-jointed ; pronotum very long, rounded iu front ; scutellum the 



parapsidal furrows distinct Sycobia Walker (type S. bethyloides Walk.). 



38. Stigmal vein rather short, less than one third the length of the marginal ; antennae 13-jointed, with 2 



ring-joints and a 6-jointed funicle Trichaulus Mayr. 



39. Antennae 13-jointed, with 2 ring-joints ; mesonotum with distinct parapsidal furrows. 



Pronotum quadrate, a little narrower than the mesonotum ; scutellum with two grooved lines ; 

 abdomen oval, subdepressed, much shorter than the thoi'ax, briefly petiolate, and terminating 

 in an exserted penal sheath Sycophila Westwood. 



Pronotum large, rounded anteriorly ; scutellum without grooved lines ; abdomen compressed, 

 shorter than the thorax Froggattia Ashmead 



Subfamily IT. ToRYMiNiE.

Synop., p. 67.

 1871. Torymides, Subtribus (partim) Thomson, Hym. Skand., IV., pp. 59, 64. 

 1899. Toryminse, Subfamily II., Ashmead, Proc. Ent. Soc. Washington, IV., p. 247. 



The vast majority of the species falling in this group are parasitic on gall-inhab- 

 iting insects, belonging to the orders Hymenoptera and Diptera, although others are 

 recorded as having been bred from Coleoptera, Lepidoptera, etc., and from the nests 

 of bees and wasps. 



I think it quite likely these latter records are erroneous, and that the Coleoptera, 

 Lepidoptera, etc., had dipterous parasites from which the torymines came.
