NORTH AMERICAN BOSTRICHIDAE 143 



\ 



ADDENDA 



The following genus does not occur in Xorth America, but several 

 Xorth Aanerican species have erroneously been placed in it. They are 

 now placed in Xyloptrthella. new name. 



Genus XYLOPERTHA Guerin-Meneville 



Xylopertha Guerin-Meneville, 1845, Soc. Ent. de France Ann. (ser. 2) 3: Bui. p. 



XVII. 

 Xylonites Lesne, 1901, Soc. Ent. de France Ann. (1900) 69: 478, 575-584; 1938, 



in Junk (pub.;. Coleopt. Cat., pt. 161, p. 65. (New synonymy.) 



Genotype. — Of Xylopertha, Apate sinuata Fabricius. (Designated 

 by Gorham.) Of Xylonites, Bostrichus retusus Olivier. (Present 

 designation.) 



Guerin-Meneville described Xylopertha in a table for separating 

 genera, and in a footnote gives as the types Apate minutus Fabricius, 

 truncata Dejean, longicorrds Fabricius, sinuata Fabricius, etc., with- 

 out designating a genotype. Apate truncata is a nomen nuelum, Apate 

 minuta belongs to Dinoderu* Stephens, and Bostrichus longicornis has 

 now the genus Tetrapriocera for its reception. Gorham 12 designated 

 Apate sinuata Fabricius as the genotype of Xylopertha Guerin-Mene- 

 ville. 



Lesne (1901) apparently overlooked the designation of sinuata as 

 the type of Xylopertha, and erected Xylonites for three species, in- 

 cluding retusus Olivier (sinuatus Fabricius) without designating a 

 genotype. Xylonites Lesne (1901) must be suppressed as a synonym 

 of Xylopertha Guerin-Meneville (1845).
