A generic Synopsis of the Hymenopterous Family 



Chalcididae. 



By L. 0. Howard. 



(Continued from p. 197.*) 



Subfamily LEUCOSPIDINAE. 



This subfamily consists of the single genus Leucospis, Fab. for which 

 the characters given in the subfamily synopsis will be sufficient. 



Subfamily CHALCIDINAE. 

 Abdomen with a long petiole. Postrnarginal vein long. Posterior tibiae not spurred. 

 produced at tip into a spine. 

 ( )vipositor not exserted. 



Thorax immaculate. Middle tibia; not spurred at apex..*Genus Smicra Spinola. 

 Thorax maculate. Middle tibiae with spurs . . . Genus Spilochalcis Thomson. 



1 Ovipositor exserted, longer than the whole body Genus Podagrion Spinola. 



Abdomen almost sessile. Middle tibia: spurred. 

 Antennae inserted in the middle of the face. 



Abdomen much produced *( Jenus Phasgonophora Sichel. 



Abdomen sub-globose Genus Chalcis Fabr. 



Antennae inserted near or not far from mouth. 



Ovipositor exserted, as long as abdomen . . . . *Genus Acanthochalcis Cameron. 

 Ovipositor short, usually hidden. Posterior tibiae two-spurred. Hind femora 



normal Genus Halticella Spinola. 



Ovipositor short. Hind femora with a single large tooth 



Genus Notaspis Walker. 



Note. — In this subfamily 1 have followed Cameron, the latest au- 

 thor, in retaining Phasgonophora which Andre would combine with Hal- 

 tictlla, but have added Thomson's Spilochalcis with a view of accepting any 

 good separation of the unwieldy old genus Smicra. All the species of 

 die old genus, however, which I have seen from this country belong to 

 the new division. 



Subfamily TORYMINAE. 

 < >vipositor exserted. 



Antenna:- with two ring- joints, the flagi^lum thence 8-jointed 



*Genus Lochites Foerster. 

 Antennae with one ring-joint, fiagellum thence 8 jointed. 



Stigma! vein with a very large knob. Abdomen of male much narrowed at 



base Genus Megastigmus Dalman. 



Stigma] vein with no such knob, or with a small knob. .Male abdomen not 

 narrowed. 



■ In the synopsis of the subfamilies on p. 107 I inadvertently inserted, opposite 

 the subfamily Chalcidinae, the character "ovipositor protruding but slightly", which 

 should be changed to "ovipositor not curved over dorsum oi abdomen", in contra- 

 distinction to the Leucospidinae. The character as it stood is wrong, as in the recent- 

 ly described genus Acanthochalcis, the ovipositor is normally exserted to a con- 

 siderable length, and in Podagrion, formerly placed with the Toryminae, bul nov 

 more properly included among the Chalcidinae, the same character is found.
