States that chinch bugs are being rapidly carried away in 

 every place lately visited in Southern Illinois, by one or two 

 diseases, the same as those which heralded the disappearance of 

 the chinch bug in Central Illinois in 18.'^2. One imbeds the body 

 of the dead insect in a white fungus, the number of these 

 "moldy" chinch bugs being so great in some fields that the ground 

 is whitened as if by a flurry of snow. The other disease, recog- 

 nizable only by experts, but more general and destructive, is a 

 true germ disease, characterized by bacteria, in alimentary canal, 

 and has produced a very great diminution in numbers of chiuch 

 bugs where it prevails.

Mr. William Biehl, Washington Co., Mo., writes: "Chinch bugs 

 have suffered here from the fungus disease you speak of. I would 

 judge they are badly used up."

' Reply to a letter of inquiry from editor. In addition to infor- 

 mation given in the article in Psyche on the same subject (see 

 previous entry) the Botrytis and Entomoplithora diseases are said 

 to propagate l)y means of minute dust-like spores (growing on the 

 bodies of the dead insects) which are communicated to healthy bugs 

 through their air tubes or by falling on their bodies. Nothing 

 very positive can be said as to the usefulness of these diseases, 

 but in 1865, in Northern Illinois, a chinch-bug army disappeared 

 with a disorder that may have been identical with one of the fungus 

 diseaseB lately observed; and in 1882 the bacterial atftu-tion noticed 

 this year prevaiknl generally in tlie vicinity of Bloomington and 

 Ciiampaign (III), the cliinch bugs the following year l)ejng re 

 ducod to insignificances in those regions. No tnices of disonses
