N. R. — It is to the generosity 01 Mr. Liebeck, who has devoted much 

 of his time to the matter, that the News has been able to identify Coleop- 

 tera for its subscribers. As Mr. Liebeck now desires a well-earned vaca- 

 tion, subscribers are requested not to send any more Coleoptera for iden- 

 tification until after September i, 1894, as such specimens cannot receive 

 attention until that time. — Eds.
