26 Psyche [February- 



Brazilian species is said (1. c.) to present transitions to certain 

 Pristomerini and Cremastini, and it would appear on the other 

 hand that the present species shows characters also which ally 

 it with Eiphosoma and the related Xiphosomella. 



Mr. H. L. Viereck, of the U. S. National Museum has very 

 kindly compared the drawing of the wing of this species reproduced 

 on the accompanying plate as figure 10 with the specimen of 

 Porizon agilis Cress, on which Ashmead based the genus Pristo- 

 meridia and writes me that ' 'it agrees with the type except in having 

 an areolet and no indication of a break in the nervellus." I believe 

 thereforethatit should beplaced in this genus. Ithasbeensuggested 

 by Szepligeti that Pristomeridia cannot be retained as distinct from 

 Pristomerus, but the present species is so different in habitus 

 from typical species of the latter, that I do not think the two 

 extremes can be considered as congeneric, whatever disposition 

 be made of the species which seem scarcely separable from 

 Pristomerus. 



Whether these Ophionine genera with toothed femora form 

 one or even two natural groups must, however, await the dis- 

 covery of other forms which will no doubt be found.
