late or early, or not at all, editors state that they have never 

 heard of serious injury to young wheat in fall, but suggest that 

 it might be well to sow late, giving current reasons for their 

 opinion. As to injury the next season, they say: "The destruc- 

 tive hosts of young chinch bugs do not make their appearance till 

 near the middle of June, and at this time the winter wheat is 

 usually too far advanced to be much injured by them. Spring 

 wheat and barley are the crops in wdiich chinch bugs have com- 

 mitted such havoc."

 1869, V. 3,. n. s., pp. 275-281.) 



Refers to chinch-bug epidemic of 1865, and to confirmation of 

 his predictions of subsequent immunity from them. Says there is much 

 more to learn about the chinch bug, some obscurity yet lingering 

 around its natural history. Speaks of larva of Hippodamia macn lata 

 and Ckysopa plorahunda feeding on chinch bugs, and states that 

 he reared the former, under confinement, to the perfect state, 

 feeding them with chinch bugs only. Details of observations and 

 experiments showing that the Chrysopa feeds voraciously upon 

 the chinch bug. Speaks at some length of the inherent proba- 

 bility of epidemic diseases among the lower forms of life, and 

 says that the causes of disease among insects are laudable and 

 proper objects for the study of the practical entomologist.

 Commiss. Agric, 1870, p. 89, fig. 59.) 

 Gives short general account of the chinch bug. Eggs deposited 

 in ground — about five hundred by one female. The insects, both 

 larva and pupa as well as the imago, "puncture and apparently 

 poison the terminal shoots, buds, and the most succulent parts, of 

 growing plants of grain, grass, maize, potatoes, and other vegeta- 

 bles, but do not attack woody plants." Two broods annually; per- 

 haps three in the South. Most destructive in hot dry summers; 

 heavy rains said to destroy them. Early grain most likely to 

 escape their ravages. As remedies, recommends rolling, burning 

 dead vegetation and rubbish along fences, burning dry straw on 

 spots where they congregate, and sowing gas lime broadcast over 

 infested fields (six or seven bushels to the acre) or dropping a 

 handful of it on each hill of corn when infested. He says: "Ac- 

 cording to Dr. Shimer, coal-tar is of no use as a remedy. Quails 

 are said to feed greedily upon the insects, and should therefore 

 be protected."

 Bugs, Potato Beetles, and Codling Moths. ( Prairie Farmer,

Makes general mention of the chinch-bug situation in Illinois, 

 stating that the insect hibernated in moderate numbers, and as 

 grain was sown early he does not apprehend disastrous visitation 

 unless June should be hot and dry. Awaits developments.
