Hickory Handles: Navy Department Specifications. Washing- 

 ton, D. C. 1914. Pp. 24. 



The Navy Department has issued a neat booklet of specifica- 

 tions for hickory handles, copies of which can be obtained upon 

 application to the various Navy pay offices or to the Bureau of 

 Supplies and Accounts, Navy Department, Washington, D. C. 



All commercial species of hickory are admitted and no discrimi- 

 nation is made against Red hickory. Handles entirely of heart- 

 wood and those showing part heart and sap (mixed hickory) will 

 be accepted. Emphasis is laid upon the weight of the wood and 

 the number of rings of growth to the inch of cross-section. Light 

 weight wood is excluded, and wood weighing 37^ pounds or 

 less per cubic foot of solid dry wood is considered light wood. 

 Wood with more than 20 rings per inch on either end is not 

 acceptable. 



Preliminary Classification of the Superfamily Scolytoidea. By 

 A. D. Hopkins. Technical Series, 17, Pt. H, U. S. Bureau of 

 Entomology. Washington, D. C. 1915. Pp. 165-232. 



This is the third contribution toward a monograph of the 

 scolytoid beetles which are represented in North and South 

 America, Europe and Asia by some of the most destructive ene- 

 mies of forest trees and their commercial products. Its object 

 is to discuss the taxonomy and present a preliminary classifica- 

 tion of the families and sub-families of the scolytoid beetles of 

 the world. 



Classification of the Cryplmlinae, with Description of New 

 Genera and Species. By A. D. Hopkins. Report 99, U. S. De- 

 partment of Agriculture. Washington, D. C. 1915. Pp. 75. 



This is the fourth contribution toward a monograph of the 

 scolytoid beetles. The sub-family Cryphalinae includes a group 

 of ambrosia beetles, also known as pinhole borers and timber 

 beetles, which are very detrimental to forest products. This 

 report names, describes, and classifies a lot of undescribed species 

 and genera as a basis for a detailed study of their habits and 

 seasonal histories, and of the methods for combating them.
