Thomas (1. c.) also described a species which he named Rhi- 

 zobius eleusinis. In the Bureau collection there are speci- 

 mens, of this species reared by Mr. Pergande from the roots 

 of Elc-usine indica Gaertn. and determined by him as eleusinis 

 Thos. These seem to agree in all important details with sum- 

 mer specimens of querci Fitch. The apterous forms agree 

 well with the description given by Thomas. It seems evident 

 then that eleusinis is a synonym of querci. 



Wilson (1911) has recently described a species of Anoecia 

 under the name of oenotherae. The principal differences be- 

 tween his species and querci are said to be the small sensoria 

 on the antennal segments. These and the color are given as 

 characters. As has been mentioned, the sensoria upon the 

 spring and summer forms of querci vary greatly, sometimes 

 being small and circular, sometimes large, sometimes absent 

 altogether with the exception of the permanent ones.. The 

 color also shows considerable variation in the main body color, 

 though the black lateral patches are usually about the same. 



The writer is inclined, therefore to believe that oenotherae 

 is only another of the root-feeding forms of querci, which in 

 the particular case was feeding upon Oenothera. That the 

 forms do not migrate in the regular way can hardly be taken 

 as evidence of a distinct species. The writer has summer 

 forms of corni taken on wheat roots in April and it was evi- 

 dent that two generations at least had already lived there. In 

 the same way, summer specimens of querci can be found very 

 late in the year upon the roots of various plants, much later 

 than the usual migration period. The proportion of the seg- 

 ments seems, however, to be different in the measurements 

 given by Wilson.
