 270, figs. 187, pis. Id). — This bulletin is divided into two portions, the 

 first of which is devoted to a popular discussion of the various insects 

 injurious to vegetation during 1896, while the second forms a popular 

 treatise on the parasites of man and domestic animals. 



In the first part some 17 insects that have been more or less injurious 

 in the past or which have recently become so are discussed. The chinch

During 1895 diseased spores were scattered in many places, and it 

 appeared from the absence of the bugs in these places at the beginning 

 of the succeeding year that good results had been obtained. At any
