I liave divided it into four triljes, wliich nic\v be distinguished by the characters 

 made use of in tlie following table : 



TABLE OF TRIBES. 



1. Abdomen sessile 2 



Abdomen petiolate 3 



2. Postmarginal vein wanting or only slightly developed, tlie stigmal vein very short, sometimes absent ; 



antennfe inserted close to the mouth border 5 



Postmarginal vein always well developed, the stigmal vein rarely very short. 



Antennae inserted near the middle of the face, or at least always above an imaginary line 



drawn from the base of the eyes Tribe I. Chalcidini. 



AntenniB inserted near the mouth border, or always beloiv an imaginary line drawn from the 

 base of the eyes Tribe IV. Haltiehellini (partim). 



3. Antennre inserted near the moutli border, or always below an imaginary line drawn from the base of 



the eyes 5 



Anterinffi inserted near the middle of the face, or always above an imaginary line drawn from the 

 base of the eyes 4 



4. Postmarginal vein very long ; ovipositor if prominent not very slender, the eighth dorsal segment often 



produced into a long compressed stylus Tribe II. Smicrini. 



5. Head normal, not cornuted. 



Abdomen petiolate .Tribe III. Chalcitellini. 



Abdomen sessile Tribe IV. Haltiehellini. 



Head abnormal, deeply excavated in front, cornuted ; abdomen petiolate or .subpetiolate. 



Tribe V. Dirhinini 



Tribe I. Chcdcklim. 



This group is distinguished by the sessile abdomen and b}^ having the antennae 

 inserted nearthe middle of the face or at least never below an imaginary line drawn 

 from the base of the eyes. 



Through the genus Aamthochalcis it is related to the subfamily Leucospidinx, 

 while in the abdominal peculiarities of most of the species the group is much closer 

 allied to the tribe Haltiehellini. 



Most of the genera attack principally lepidopterous insects in the pupal stage. 

 Phasgonophora, however, and probably also the allied genera Trigonura, Sti/piura, 

 etc., prey upon wood-boring coleopterous larvae. 



TABLE OF GENERA. 



1. Females 2 



Males 12 



2. Scutellura normal, unarmed, altliough sometimes with a slight median depression towards apex ; if 



with a slight elevated plate behind, the same is entire, rarely subemarginate 3 



Scutellum posteriorly armed, emarginate or produced 8 



3. Abdomen not ending in a long, di.stiuct ovipositor, although the eighth dorsal segment is often much 



produced, long and compressed, resembling a stylus and enclosing the ovipositor 4
