The Argentine ant, W. Newell and T. C. Barber ( U. S. Dept. Agr., Bur. 

 Ent. Bui. 122, pp. 98, pis. 13, figs. 13). — This account of Iridomyrmex humilis 

 presents the principal results of 5 years of almost constant observations and 

 experiment by the senior author at Baton Rouge, La., and in the orange-grow- 

 ing section of the same State, together with observations made by the junior 

 author in New Orleans in connection with investigations of sugar cane insects. 



The subject is taken up under the headings of history and distribution, means 

 of dispersion, economic importance, systematic position, methods of study, life 

 history, the colony as a whole, relations with other Arthropoda, natural con- 

 trol, and methods of repression. A bibliography is appended. 



Much of the data here presented have previously been noted from other 

 sources (E. S. R., 21, p. 350; 22, p. 656).
