THE PRINCETON COLLECTION OF FOSSIL BEETLES 

 FROM FLORISSANT. 



By H. F. WiCKHAM, Iowa City, Iowa. 



Through the kindness of Professor Gilbert van Ingen, 

 of the Department of Geology of Princeton University, I have 

 been allowed to study the collection of Florissant fossil beetles 

 in his care. The series is of particular interest since it forms 

 a part of the material used by Scudder in working up two 

 of his principal papers on the Tertiary insects* and contains 

 many of his types and cotypes. He studied the present col- 

 lection with special reference to the Adephaga, Clavicornia 

 and Rhynchophora and in these groups described practically 

 all of the novelties which were in sufficiently good condition 

 for that purpose. With the exception of Atcenius patescens, 

 for the determination of which I am responsible, all of the species 

 attributed to his authorship in the following list were identified 

 by him and the specimens represent the originals which served 

 as the bases of his descriptions. Those attributed to myself 

 are either lately published or now in press elsewhere. Ten 

 are described as new. The drawings are made with a camera 

 lucida and represent only what actually remains of the specimens, 

 there being no attempt to restore lost parts or to idealize any of 

 the characters. 



As in all collections of fossil insects, a good many of the 

 specimens are in too poor preservation to repay study, but 

 it is possible to recognize the forty-two species listed below.
