II. — Notes on the Lamellicorn Genus Popillia and Descrip- 

 tions of some new Oriental Species in the British Museum. 

 By Gilbert J. Arrow. 



(Published by permission of the Trustees of the British Museum.) 



In Dr. Kraatz's list of the species of Popillia in the 

 Deutsche ent. Zeitschr. 1892 (p. 303), lamentable confusion 

 was introduced into the classification of this difficult genus. 

 Dr. Kraatz's collection has happily become accessible, and 

 the specimens of Popillia from India and China have been 

 kindly sent to me for examination by Herr Schenkling. 

 Hence the present notes. Having also examined the types 

 of Hope and Newman in London and Oxford, and a number 

 of Fairmaire's in the Paris Museum, 1 am able to at least 

 partially correct the confusion which has resulted from the 

 inadequate descriptions of all those writers. Not only has 

 Kraatz misapplied the names given by all his predecessors 

 mentioned, but he has burdened his catalogue with numerous 

 names of colour-varieties, which in several cases are not 

 varieties of the species to which he has assigned them. He 

 has not avoided the repetition of the same name for these 

 varieties (e. g., cupricollis occurs three time3 and tesiacei- 

 pennis twice), and so evidently did not contemplate their use 

 as specific names in any case ; and as they are merely 

 descriptive of the colours of individual specimens, and are 

 sometimes left to explain themselves without any attempt at 

 definition, they are evidently not applicable as specific names. 

 This is also the case with the many varietal names intro- 

 duced by Ohaus, who has a var. testaceipes of P. complanata, 

 Newm. (the new species P. pulchripes of the present paper),
