species varies in size from 10 to 20 mm. and from having the posterior 

 femora black (type of horealis) to rufous (type of occidentdlis and 

 most of the other specimens). In some few specimens the sides of 

 the propodeum and the metathorax are rufous but in most of them 

 they are black.

The genus Poemenia was first recognized by Holmgren for a species 

 which he described under the name notata. A few years later Foerster, 

 recognizing Holmgren's genus, separated off certain other species 

 (none mentioned by name) as the genus CaUiclisis because they 

 lacked the areolet. Two years after Foerster's work was published 

 Cresson placed one American species in a new genus, Euxorides, 

 which he considered closely allied to Deuteroxorides but distinguished 

 from it by the presence of an areolet. Although the type of Poemenia 

 is not available there seems, to the author, no reason to consider that 

 it is different from the other two genera. The only difference wliich 

 has been offered is the absence of the areolet and this is not even a 

 specific character as in some specimens it is present in one wing and 

 completely wanting in the other. The suppression of Galliclisis is 

 further supported by the fact that Dr. A, Roman has given the 

 United States National Museum specimens of the genotype of Gallic- 

 lisis labeled as Poemenia (Galliclisis). The presence of an inner tooth 

 on the mandibles, the nondepressed clypeus and the short last tergite 

 in the female makes Poemenia a somewhat discordant element in the 

 tribe Xoridini, but in general appearance, and in most of the char- 

 acters of the head, thorax and abdomen, it so closely resembles Deuter- 

 oxorides that it is certain that it belongs near it. The characters used 

 in the above key, however, show how easily they may be distin- 

 guished.
