ARTICI.E V. — Phyllophaga Harris {Lachnosterna Hope) : A Re- 

 vision of the Synonymy, and one New Name. By Robert D. Glas- 

 gow, Ph.D. 



In few genera of equal economic importance has greater confusion 

 existed, either in collections or in the published work on the group, 

 than in the assemblage of species known to American and English 

 entomologists as Lachnosterna Hope, and to European entomologists 

 as Ancvlonvcha, Deiean.

»^^w.v^».o xiii,^ .j^^ii iiiaiac 111 Luu lew locanties, particularly in too few 

 localities that have a critical significance for the group, and the deter- 

 minations in the published lists, based usually upon external characters 

 alone, were too frequently inaccurate to make even the existing rec- 

 ords available for the proposed studies. 



The w^ork of Dr. George H. Horn (1887) on Phyllophaga is more 

 complete and more nearly monographic in nature than that of any 

 other author; yet Dr. Horn says of the group: " It is not surprising 

 that attention has not been given to the species as the literature at 

 present available does nt^t give great assistance, and in my oicii case 

 there was almost equal difficulty in arriving at a correct determination 

 of the species with the types for comparison along with the literature." 

 And again, Dr. Horn says : "Lachnosterna is certainly one of the 



most difficult genera in our fauna ".*
