to the genus Belonocnema, thus strengthening the supposition. The 

 writer thus proposes to transfer the maker of this oak leaf-pea gall 

 to Belonocnema, leaving the proof of the association with treatae to 

 others. It appears, however, that the maker of these pea galls is still 

 undescribed. Ashmead reared a single fly in February supposedly 

 from over 200 of these galls and described it as Cynips q. virens, trans- 

 ferring it to Andricus later, but the type fly in the United States 

 National Museum has a question mark after the genus. This type is 

 in bad condition, but agrees with the description, and is plainly a 

 Disholcaspis and agrees with DisTiolcaspis Jicigera, a gall of which had 

 evidently been mixed in with the others by mistake, and such a gall 

 was found in the Ashmead duplicate gall collection in a box of oak 

 leaf-pea galls which may have been his breeding cage. Thus the 

 single fly reared was associated with the wrong gall, a mistake which 

 would not have occurred had the species been described from ade- 

 quate material. As the classification of the Cynipidae must be 

 based upon the aduits rather than upon their work, the maker of the 

 stem gall known in literature as jicigera must take the oldest name 

 applied to it, namely, virens, and the maker of the leaf gall needs 

 description. However the leaf-pea gall-fly of Florida proves to be 

 different from those from similar galls in Texas so that there are two 

 species to describe. Although somewhat outside the scope of the 

 present paper, these changes are here included, and the synonomy 

 of each species follows, together with field notes on each.
