ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 363 



Subfamily II. Mymarin^. 



In this subfamily fall some of the smallest Hymenoptera known, hardly visible 

 to the naked eye, and living parasitically in the eggs of some other small insect. 



The group is distinguished by having the tarsi 4-jointed, not 5-jointed as in the 

 Gonatocerinse. 



It is divided by the attachment of the abdomen into two tribes. 



TABLE OF TRIBES. 



Abdomen sessile or subsessile Tribe I. Anapbini. 



Abdomen distinctly petiolate Tribe II. Mymarini. 



Tribe I. Anaphini. 

 The sessile abdomen distinguishes the tribe. 



TABLE OF GENERA. 



1. Females 2 



Males 4 



2. Antennae more than 8-jointed 3 



Antennse 8-jointed Anthemus Howard (type A. chionaspidis How.). 



3. Antennse 9-jointed. 



Marginal vein lengthened Anaphes Haliday (type A. fuscipennis Hal.). 



Marginal vein not lengthened Anagrus Haliday (type Ichneumon atomus Linne). 



4. Antennse more than 9-jointed 5 



Antennse 9-jointed Anthemus Howard. 



5. Antennse 12-jointed ; marginal vein long Anaphes Haliday. 



Antennse 13-jointed ; marginal vein short Anagrus Haliday. 



Tribe II. Mymarini. 

 In this tribe the abdomen is always distinctly petiolate, never sessile.
