Hab. New Žealand. 



Found by the late Mr. Percy Earl, who collected this and many 

 other objects of natūrai history now in the British Museum. The 

 Dendroblax Earlii, "VVhite, a very interesting Lamellicorn Beetle, 

 allied to Ryssonotus and Lamprima, but with much of the aspect of 

 an Oryctes, was named in compliment to him in the " Insect Fauna of 

 New Zealand," published in one of the numbers of the ' Zoology of 

 H.M.SS. Erebus and Terror.' Much ■vs'as expected from him ; bi*t he 

 was drowned in a lamentable shipwreck ofF the Australian coast. 



It is distinct" from any species described by Prof. Milne Ed\vards, 

 Dr. Erichson of Berlin, or Mr. Gray in the ' Appendix to Eyre's 

 Central Australia,' published in 1845.
