NOTES ON CHRYSOMELID BEETLES OF THE SUBFAMILY 

 CHLAMISINAE, WITH DESCRIPTIONS OF NEW SPECIES 



By F. Monr6s 



Among some chrysomelid beetles of the subfamily Chlamisinae 

 that I received for study from the United States National Museum 

 are several of considerable interest, and these, together with notes on 

 certain others of the same group received from other sources, form the 

 subject of the present paper. I wish to express my thanks to Mrs. 

 Doris H. Blake, who facilitated my borrowing material from the 

 United States National Museum, and to the authorities of the National 

 University of Tucuman, Argentina, for permission to publish the 

 result of my researches. 



One new species is added to the hitherto known forms of the genus 

 Melittochlamys. The status of the known species of this genus is 

 set forth in the key.
