862 NEW SPECIES OF COLEOPTEROUS INSECTS. 



I have named this species in honour of the author of 'Il- 

 lustrations of British Entomology,' to whom I am indebted 

 for much information and kindness. 



Art. X. — Descriptions of some new species of Coleopterous bi- 

 sects. By Edward Newman. 



Natural Order.— CZE'/^/rJS'^S', Newman. 

 Genus. — Hydnocera, Newman. 



The genus Hydnocera was established in the ' Entomologi- 

 cal Magazine,' vol. v. page 379. It approaches, in many 

 essential characters, the genus Tillus of Fabricius, who pro- 

 bably would not have considered it as generically distinct. 

 One of the species has been described by Germar in his * In- 

 sectorum Species,' under the name of Clerus humeralis ; and 

 the same insect has also been labelled as the Tillus humera- 

 lis of Say, but I have no reference whatever to any descrip- 

 tion by the American entomologist. A second species [Hyd. 

 serrata) has been named by myself, and recorded as captured 

 by Mr. R. Foster, at Mount Pleasant, in Ohio : and three 

 others are now added to the list. All the five inhabit the 

 United States of North America. 



The Count Dejean, in his ' Catalogue des Coleopteres,' 

 has given to the genus the provisional name of Fhyllohmius; 

 this I learn from finding one of the species so named by Dr. 

 Harris. I observe with regret that the plan of giving trivial 

 names, without taking the trouble to secure them by the pub- 

 lication of a brief descriptive character, does not meet with 

 that neglect and contempt which such a practice deserves ; 

 on the contrary, I have not unfi-equently seen these spurious 

 names attached at random to the genera and species that 

 happen to stand unnamed in a cabinet ; and names thus ar- 

 bitrarily imposed in the first place, and subsequently applied 

 by guess, are becoming rife in the majority of our collections 

 of exotic Coleoptera.
