and Species of Eumolpida. 881 



sion of any one of these from a mere nominis umbra to a sub- 

 stantial reality will be a step in the right direction. 



The following list will show which of Dejean's or Chevrolat's 

 genera have been described ; an asterisk prefixed denotes that 

 they are only described imperfectly. We have also prepared a 

 catalogue of described species of the entire group of the Eumol- 

 pidse, which is far too long for insertion here ; but, as it is ne- 

 cessarily in a state of progressive improvement, its publication 

 may well be delayed to a future occasion. In the following list, 

 small capital letters indicate the name now adopted : references to 

 the descriptions are added, as their insertion may be of some 

 utility.

Colaphus is omitted, as not belonging to the Eumolpidse. 

 Bromius will probably have to be retained (as only partly syno- 

 nymous with Adoxus of Kirby and Baly) for the reception of 

 B. hirtus, Fab., and its allies, which are excluded by Mr. Baly 

 from the genus Adoxus. Bromius (one of the names of the god 

 of wine) was adopted with special reference to the habits of B. 

 vitis, Fab., which destroys the vines in Southern Europe. It 

 would have been better therefore to have preserved the name 

 Bromius than Kirby's Adoxus. That writer proposed, it would 

 seem, to discard Eumolpus altogether, inventing the two names
