Preoccupied Generic names of Coleoptera. 

 By T. D. A. Cockerell. 

 In the course of my work on the list of Coleoptera of New 

 Mexico, I have been struck by the number of preoccupied 

 generic names which are still allowed to stand in our cata- 

 logues. It occurred to me that it would be a useful service to 

 make a complete list of these, and to this end I have examined 

 every name given as valid in Henshaw's list, with respect to 

 homonomy. As a result, I find nearly fifty names which are 

 absolute homonyms, and a large number which differ from 

 earlier named only in some minor feature (e. g. termination 

 indicating gender), and would be considered homonyms by 

 many. These latter should not, I think, be disturbed. I 

 have not examined the names of the numerous genera described 

 in recent years, since the publication of Henshaw's catalogue. 

 In my manuscript, I have provided substitute names for nearly 

 all the homonyms, but only part of them are given here, as 

 although I have made much search for available synonyms 

 myself, and the list has been kindly looked over by Mr. Fall, 

 there is still a probability that several available substitute 

 names will be discovered in the older literature. It is hoped 

 that those who are aware of such will record them. 



CARABID^E. 



1. Diplochelia Brull£, 1835 {Diplochila of our lists), is Rembus, Latr.» 



1817. The latter name was alleged to be preoccupied, but ap- 

 parently in error ; hence it should be used for our species. 



2. Diaphorus Dej., 1831 (not Meig., 1824). 



3. Euprocttis Sol., 1851 (not Gene\, 1840). 



4. Nothopus Lee, 1852, is Euryderus Lee, 1848, not Eurydera Lap. I 



do not consider these names the same, and think that Eury- 

 derus should be restored. 



HYDROPHILID^E. 



5. Helopeltis Horn, 1873 (not Signoret, 1858) = Helopeltina n. n.; spe- 



cies Helopeltina larvalis (Horn). 



SILPHID^E. 



6. Pelates Horn, 1880 (not Fisch, not Cuvier) = Pelatines n. n.; spe- 



cies Pelatines latus (Mann.). 



7. Aglyptus Lee, 1866 (not Foerst, T856) = Aglyptinus n. n.; species 



Aglyptinus lecvis (Lee).
