 Scudder they may yet be found among the material collected by 

 him at his chief station on Fossil Stump Hill, distant something 

 over four miles by road. The preponderance of Rhynchophora 

 is exhibited here as in all the other collections, this group furnish-

 the discovery of three new Scolytids helps to remove a deficiency 

 in what is today a numerous group. The Bruchid» or seed- 

 weevils have supplied two more novelties; it is evident that the 

 familv was numericallv stronger than today. Another Chrys-
