 Vers. Stat., 49 ( 1891 i. No. 1-2, pp. 83-95). — The author reviews the literature relating 

 tn this subject and shows that the barberry is a host plant for some phases of rusts, 

 and on this account the destruction of all hushes in cereal-growing regions is 

 advised. Directions for their eradication and control are niven.

The evolution of economic entomology, C. H. Fernald (pp. 5-12). — The 

 history of the subject is briefly traced from the earliest times to the 

 present. In speaking of the future development of the subject, it is 

 shown that the assistance of the chemist and the physiolgist will be 

 needed. 



Sometemperature effects on household inserts, L. 0. Howard (pp. 13-17). — 

 From temperature experiments performed to learn the degree of tera- 

 perature that will prevent the ravages of the common clothes moth 

 (Tinea biselliella), the black carpet beetle (Attagenus piceus), the leather 

 beetle (Dermestes vulpinus), the dark meal moth (Tenebrio obscurus), 

 and the cabinet beetle (Trogoderma tarsale), it Mas found that during

 the purpose indicated.
