No. 2317. FIVE TRIBES OF WUNEUMONINAE—ROHWER. 429 



short inner tooth; clypeus transverse, apically depressed so there 

 is a more or less distinct mouth opening, or convex and without a 

 mouth opening (Poemenia); thorax depressed; mesepisternum 

 longer than high; prescutum long, usually completely defined; 

 wings placed much behind the middle of thorax; propodeum shorter 

 than the scutum; legs usually simple, always simple in male, but 

 in some Jemales (genus Xorides) the tibiae are constricted; claws 

 simple; wings usually without an areolet; abdomen longer than 

 head and thorax; ovipositor long, cylindrical. 



The three genera belonging to this tribe may be easily recognized 

 by the following table: 



TABLE TO THE QENEKA. 



1, Eyes parallel or nearly; malar space long; propodeum areolated-.A^orif/es Latreille. 

 Eyes strongly converging toward the clypeus; malar space very narrow ; propodeum 



not areolated 2. 



2. Mandibles without an inner tooth; apical part of clypeus depressed so there is a 



distinct mouth opening; posterior orbits with a raised ridge which is covered 

 with transverse rugosities; areolet wanting; apical tergite of female long, some- 

 what trowel-shaped Deuteroxorides Viereck. 



Mandibles with an inner tooth; clypeus not depressed apically; posterior orbits 

 without a raised ridge; areolet often present; apical tergite of female short.

The genotype of the genus Xorides Latreille is a species which up 

 to the present time has not been recognized by European writers and 

 it was impossible for the writer to determine to which group, of the 

 long recognized genus Xijlonomus, it belonged. Inasmuch as it was 

 very desirable to know something about the species the assistance of 

 that careful European authority of Ichneumonoidea, Dr. A. Koman, 

 was sought and under date of February 14, 1916, he replied as follows: 



"I have the pleasure to inform you that the Xorides indicatorius 

 Latr. was fortunately easy to find out. It is, without any doubt, 

 the same species as Xylonomus ferrugatus Grav. Ichn. Fur. 3, p. 840,
