TABLE OF GENERA AND SPECTES HERE 

 CONSIDERED. 



1 (6) Abdomen sessile, with a wide thoracic mesophragma 



extending well into it ; front wings very narrow, the 

 apical cilia much longer than their width. 



2 (3) Tarsi 5-jointed (antennae of male lo-jointed ; of female 



8-jointed) Alaptus inuiialiinis. 



7. (2) Tarsi 4-jointed (antennae of male 13, of female 9-joint- 

 ed.) 



4 (5) Third antennal joint elongate almost as long as the 



fourth Paraiiagrus. 



Ovipositor only slightly exserted l:)ehind the body. 



P. optabilis. 



Ovipositor exserted behind the body for a length 

 equal to that of the 4 joints of the hind tarsi together. 

 P. perforator. 



5 (4) Third antennal joint very short, much shorter than 



fourth Anagrus. 



Front wings with a distinct bare longitudinal line on 



lower half A. frcqucns. 



Front wings more evenly hairy (PI. XIll fig. 8 & 8a.) 

 A. coliimbi. 



6 (i) Abdomen pedicellate or subpetiolate, and without a 



mesophragma extending back into it ; front wings 

 with the apical fringe short, much shorter than the 

 width of the wings.

Abdomen pedicellate Polyiicmo rcduvioU. 



DESCRIPTION OF GENERA AND SPECIES. 



In the following descriptions important structural characters 

 are generally given under the generic names, owing to the fact 

 that I do not feel sure that the species are always placed in the 

 right genera, for reasons that I have already stated. The neu- 

 ration does not differ greatly in these g^enera, being much as in 

 the Paraiiagrus figured, though in some forms the sub-marginal
