EUQNAMPTUS Sch. 



The species of this genus are more slender in form than the other mem- 

 bers of the family, and the legs are longer and more feeble. According to 

 the punctuation of the head, prothorax aud elytra, the species may be 

 readily recognized : 



Elytral interspaces very narrow 1. striatus. 



•' " wider than the striiB. 



Front not channeled. 



Head feebly punctured, narrowed behind. 2. angustatus. 



" " not " " 3. coUaris. 



" more strongl}^ punctured, antenna; stouter.. . 4. punctieeps. 

 Front distinctly channeled , . 5. sulcifrons. 



1. Eu. striatus, n. sp.
