ENTOMOLOGICAL SECTION. XXIU 



Dr. Horn exhibited the drawings which form the eight plates to 

 accompany the paper presented for publication. Special attention was 

 called to those figures which illustrate the definition of the families 

 composing the Adephagous series of Coleoptera, a discussion of this 

 matter being necessary before a consideration of the Carabidae. This, 

 Dr. Horn said, was necessary in consequence of the diverse opinions ex- 

 pressed by various authors concerning Amphizoa, PeloUus and Haliplus. 

 By well defined structural characters not hitherto observed it was shown 

 that these are really types of distinct families equivalent to the Carabidse 

 or Dytiscidfe. Dr. Sharp in a late paper had included Amj^hizoa and 

 PehbiuH in the Dytiscidfe while Chaudoir's latest opinion was in favor 

 of retaining the former in the Carabidae. 



Dr. Horn stated that he regretted to differ so completely with such 

 eminent authority, but the characters in which these genera differ from 

 all others of the Adephagous series are of such an important nature that 

 he insisted on maintaining the view originally expressed by Dr. Leconte 

 of the position of Amphizoa. 



Attention was also directed to two finished plates illustrating genera of 

 the Serricorn series, the text being nearly completed by our printer. 



Dr. Horn announced the decease of Baron de Chaudoir, an eminent 

 Coleopterist of Europe and a corresponding member of the American 

 Entomological Society.
