Rev. A. Matthews on neio CorylophiilEe. II I 



leviter sinuata, angulis acutis ; elytris pronoto sesquilongioribus, 

 baud latioi'ibus, ad humeros latissimis, sat profunde punctatis 

 lateribus leviter marginatis, apice obtuso ; pygidio minime ex- 

 serto ; pedibus atque antennis rufo-testaceis. 



I feel much pleasure in naming this remarkable species 

 after Mr. C. O. Waterhouse, in return for the valuable assist- 

 ance I have often received from him. The unique example 

 in the collection of the British Museum was found in Chili.
