I take pleasure in naming this insect after my correspondent, Dr. B. 
Foerster, of Mulhouse, Alsatia, whose recent researches upon the fauna, and 
especially the insect-fauna, of the Oligocene of his district are well known 
and important.

Tribe EVR aN TING: 
No tribe of Curculioninze shows such a variety of structural forms in 
the Tertiary deposits, whether of Europe or America, as this. In Europe 
no less than nine genera, with thirteen species, have been recognized, namely : 
Bagous, with three species at Brunstatt and Corent; Hydronomus, one spe- 
cies at Aix; Tanysphyrus, the same; Erirhinus, the same; Notaris, recog- 
nized by Curtis at Aix; Dorytomus, recognized by Serres at Aix; Erycus, 
two species in the Pleistocene of Hisbach; Smicronyx, one species at Brun- 
statt; and Erirhinoides, an uncharacterized extinct genus, with one species 
in amber. In America we find seven genera and nine species, all of which, 
with a single exception, come from Florissant. Of the genera found also in 
the European Tertiaries, we have Dorytomus, with two species; Erycus and 
Erirhinus, each with one; besides these Grypidius, with one species, and 
Procas, with two, one of which occurs only in the Gosiute fauna; while 
there are also two extinct genera, with one species each, Numitor and 
Smicrorhynehus.
