Alexander, Bond, Edwards, Jefferson, and Monroe counties in 

 Southern Illinois report great injury from chinch bugs; and 

 Grenola [Elk?], Franklin, and Panorama [?] counties in Kansas; 

 Felton [Fulton], and Highland, in Ohio; and Howard in Indiana, 

 report considerable injury. "("Farmers' Beview Crop Summary for 

 May 30, printed in advance in "Omaha Daily Bee," May 31,

Under dates of July 2, 9, and 10, and Aug. 5, 1886, the follow- 

 ing counties in Nebraska report injury to wheat, in three instances 

 to oats, and in one to corn: Adams, Clay, Fillmore, Howard, 

 Saline, Saunders, and York. Under date of July 16, chinch bugs 

 are reported to have destroyed much wheat and oats in Webster 

 county, Iowa.

Damage by chinch bugs in Iowa in 1887 nearly $25,000,000. 

 Summary of life history and habits, and detailed account of obser- 

 vations at Ames. First damage noted in June, to wheat. On 

 corn and Hungarian the middle of July, mostly in adult and pupa 

 stages; many adults pairing at this time. Seen taking wing July 

 16. Eggs plenty in ground at base of corn stalks, between sheaths, 

 etc., July 19, some nearly ready to hatch. July 25 and 27 swarm- 

 ing, flying with the wind: no pairing noticed. Aug. 3, newly 

 hatched bugs plentiful; some on corn, but more on roots and 

 stems of foxtail grass. Hungarian, late-planted on sod, suffered 

 severely. Weather dry. Aug. 13, bugs were going from the Hun- 

 garian to corn. As late as Nov. 15 adults were in the fields. Kero- 

 sene emulsion, five or six per cent., killed the bugs very quickly; 

 less than four or five per cent, was unsatisfactory. Can hardly 

 prove of value except when bugs are massing on corn. Great 

 numbers were destroyed by burning stubble and grass. Fire should 

 be started in hottest part of day, when greatest numbers will be 

 moving. A couple of furrows plowed between grass and corn and 

 kept pulverized w(?re effective. To prevent migration from wheat 

 to corn, furrows should be i)lowed several days b(^fore migration 

 begins, two or three time pulverized, and as soon as there is any 

 sign of migration, a weighted trough should be drawn along the 

 furrow to reduce the sides to dust, this process to be repeated 

 j'very dry, liot day, by ten o'clock, as long as bugs attempt to 

 i>as8. .Experiments were made with pyrethrum and bisulphide of 

 carbon, the former pioviiig entirely unsatisfactory and the latter 

 needing further trial. Preventive measures must be the nm'm
