 Div. Ent., U. S. Dept. Agr., pp. 8, figs. 1-5. 



This circular brings the data on distribution and other features down to date, and in the matter 

 of remedies incorporates the results of field studies in Texas by Mr. ('. L. Marlatt on food habits

 steps being merely palliative or to offset the failure to adopt this method. Issued in English, Span-
