BRUCHUS Geoffroy. 



A dominant cosmopolitan genus, with abundant representation in North 

 America. Seven fossil species have been recorded from the early Tertiaries 

 of amber, Rott, Oeningen, Alsatia, and Utah. One of the two species found 

 in the Oligocene of Alsatia is regarded by Forster as identical with a living 

 form. 



Bruchus anilis.

TE rv^EBP? IOI^ID.^3il. 



Twenty species of this family have been found fossil, referred to eleven 

 genera, one of which is regarded as extinct. Only two of these species 

 occur in the Pleistocene, one in America, the other in Europe, belonging to 

 different genera; the European species is regarded as identical with a living 

 form. Besides these, undetermined genera have been found in various 

 localities. 



TENEBRIO Linne'. 



A cosmopolitan genus with relatively few species, four of which occur 

 in the United States. Two fossil species are found in the brown coal of the 

 Rhine, one in the Tertiaries of British Columbia, and one in the Canadian 

 Pleistocene.
