.^iven. The formula recommended is one originally proposed by 

 H. G. Hubbard, and is as follows: 



Kerosene 2 gallons . . . .=67 per cent . 



Common soap, or whale-oil soap ^ pound... ) oo x 



Water 1 gallon... \ P^"* 



The solution of soap, boilinpj hot, is to be added to the kero- 

 sene, and the mixture churned for five or ten minutes by means 

 of a force-pump and spray-nozzle. One part of this emulsion to 

 nine parts of water is considered strong enough. "Bogus chinch 

 bugs" are described, and figures reproduced from Riley's Seventh 

 Heport, and a bibliographical list is given of the most important 

 articles on the chinch bug from 1831 to 1887 inclusive.

The great damage done by the chinch bug in most of our 

 Western grain-growing States has been the entomological event of 

 the year. The Statistician of the Department of Agriculture re- 

 ports 860,000,000 as the very lowest estimate of damage in nine 

 States.

Chinch bugs observed in considerable numbers in March, 1887, in 

 Tensas Parish, La., about young corn, pairing and ovipositing. Said 

 to do considerable injury at times. The only small grain in the lo- 

 cality where they were observed was an occasional field of fall 

 oats or millet.

Rumors of cliincii-bug depredations were circulating the second 

 week in July, and a week later it was known that tiieir ravages 

 were not confined to Nebraska but extended into Kansas, Mis- 

 souri, Iowa, ])()rtions of Illinois, Minnesota, and Southeastern 

 Dakota. Meteorological conditions were favorable to the most 

 complete development of the bug, comparatively few natural ene- 

 mies were present, and especially in portions of Nebraska, Iowa, 

 and Kfinsas there is always grt^at carelessness with regard to rub- 

 bish. After the bugs have tx^como a pest the only effectual 

 lemedy is wet weather, which induces disease and dissolution. It 

 can be held in check by clean farming, burning rubbish in late 

 fall, winl'T, or early spring, protection of birds, — especially quails,
