Notes on Ecology of Injurious Tenebrionidae (Col.). 



By J. S. WADE, Scientific Assistant, I'.ureau of Entomology, 



Washington, 1 ). C. 



Some genera of native Tenebrionidae at one time considered 

 of negligible economic importance are becoming, in the larval 

 stage, each year more destructive to newly sown wheat and 

 other grains over the semi-arid regions of the middle and 

 western United States. The area of especial infestation com- 

 prises central and western Texas, < Iklahoma, Kansas, Nebras- 

 ka, eastern New Mexico, Ari/.ona. California, and the Pacific 

 Northwest. 



Of the family Tenebrionidae about 10,000 species of widely 

 varying form and size are known, and about 750 ot these occur 

 within the limits of the United States. In the western and 

 southwestern states where the 1 larger number of species occur 

 they, like the Carabidae of eastern localities, comprise the most 

 conspicuous portion of the Coleopterous fauna. Most () | the 

 species are black or dark brown, and some of the larger torm-, 

 have long awkward legs and a peculiar loose-jointed appearance. 

 A number of the species, notably lilcatics and Blapstinns, po
