Lachnostcrna Hope, because neither of the earlier names was sup- 

 ported by a technical description that would indicate the limits of the 

 genus. 



The name Phyllophaga is adopted by the writer on the ground 

 that its validity was fully established by its publication in connection 

 with a series of valid specific names — a position that is fully endorsed 

 by Messrs. Caudell and Banks, and by many other entomologists to 

 whom the question has been submitted — and in the absence of a desig- 

 nated genotype, the species liirticiila Knoch is here proposed as the 

 type of the genus. 



The name Phyllophaga has been proposed several times for genera 

 in widelv diverse groups of animals, but the earhest use of this name 

 known to the writer, aside from its use by Harris as cited above, is 

 that of Robineau-Desvoidy, who, in 1830, proposed this name for a 

 genus of Diptera. 



The status of the various names that have been proposed for new 

 genera to be formed at the expense of Phyllophaga, but which were 

 all suppressed by Horn, will be reserved for discussion in a later 

 paper, sihce any consideration of these names would involve inter- 

 pretations of relationship that would be out of place here. 



In several instances in the following list, names indicated as syno- 

 nyms represent geographic races or varieties; but it has seemed best 

 not to attempt to indicate the status of such names until they may be 

 discussed more fully than would be possible here. 



In this list two exclamation points before a name indicate that the 

 writer has personally studied the genital characters in the type speci- 

 men, while a single exclamation point before a name indicates that, 

 although the writer has not seen the type specimen himself, the type 

 has been dissected, and drawings of the genital characters prepared 

 for these studies.
