SUPPLEMENTARY NOTES AND DESCRIPTIONS OF NORTH 



AMERICAN OSTOMID^, CLERID^, AND 



COSSONUS (COL.). 



By Edwin C. Van Dyke, Berkeley, Cal. 



The following notes and descriptions are in the nature of an 

 appendix to two previous articles, one on certain Ostomidas* and 

 the other on the genus Cossonus.'f They are the result of addi- 

 tional material and data combined with a renewed study of cer- 

 tain of the forms. The chief source from which I received this 

 material was the U. S. National Museum, through the kindness 

 of Dr. E. A. Schwarz and Mr. H. S. Barber. Dr. Schwarz 

 also furnished me certain notes upon some of the early descrip- 

 tions which I was not able to see, as well as some notes based 

 upon his own studies.
