of timber on prairie farms is recommended as a means of attract- 

 ing birds, who are the most destructive natural enemies of 

 noxious insects. 



Eeference to statement in the "Bloomington PantagrapH" that 

 the wheat crop of McLean county will only average from eight 

 to nine bushels per acre, owing to chinch-bug injury.

 Bug. (Extract from Waukegan Gazette, also printed in 

 Country Gentleman, Dec. 21, 1865, v. 26, p. 395.) 



Prints an extract from "Waukegan Gazette," giving D. H. Sher- 

 man's theory that the eggs of the chinch bug are deposited in the 

 "fuzzy end of the kernel," and that the insect may be easily erad- 

 icated by steeping the seed in some solution which will destroy 

 the larva. Editorial comments [by C. V. Riley?] showing fallacy 

 of idea, and stating that the bugs hibernate as adults. 



Prairie Farmer, Sept. 30, 1865, v. 16, n. s., p. 253. 



Editorial note of receipt of a letter from Henry Shinier, of Mt. 

 Carroll, to the effect that farmers need not fear chinch bugs the 

 coming year as they have "all died of climatic epidemic disease."

 not in Seed Grain. 



Report of an experiment showing that egg of chinch bug is 

 not deposited in kernel.

A correspondent, address not given, thinks bugs have been killed 

 as a result of rains. Can find no living ones. Says, "There is 

 no great hazard in sowing a limited number of acres of spring 

 wheat in 1866." 



Shimer, Henry. — Description of the Imago and Larva of a New 

 Species of Chrysopa [(7. illinoiensis\ (Proc. Ent. Soc. 

 Phila., 1865, V. 4, pp. 208-212.) 



Specimens described were obtained from a field of corn (sown 

 very thick for fodder) where the larvtie were voraciously feeding 

 upon chinch bugs, which literally blackened every stalk of corn. 

 Estimates that there was. in September,, one or more of the Chry- 

 sopa larva) for every stalk of corn. One example confined in a 

 bottle victimized about a dozen bugs in quick succession, sucking 

 the juice from their bodies. Nov. 29, 30, and Dec. 1, saw this 

 and other species of Chrysopa Hying, (the weather being quite 

 warm after three weeks of severe cold, which froze the ground 

 eight inches,) and thinks it probable, therefore, that the adult 

 Chrysopa may live daring the winter, in which case, he sees rea- 

 son to hope that it will aid in suppressing the ravages of the chinch 

 bug.
