Excerpt from Twenty-Third Report of the State Entomologist on the Noxious and Beneficial Insects of the State of Illinois: Twelfth Report of S. A. Forbes In the Eighteenth Report of the State Entomologist of Illinois - the seventh of the present writer - was published the first part of a mono graph of insect injuries to Indian corn, treating of injuries to the planted seed and to the roots. The present report is in continuation of the fore going, and relates to injuries to those parts of the corn plant which are exposed above ground. Both divisions of this text have been made to include a discussion of more than the strictly injurious species, this second part especially giving practically equal attention to the corn insects generally, whether of present economic importance or not. I have, however, divided them into the more important, the less important, and the unimportant species, and have treated those notably injurious in a strictly practical manner with a minimum of technical discussion. In preparing this paper for publication I have of course drawn freely on all sources of information known to me, but owing to the large number of species included it has been impossible to give in so brief and comprehensive a paper my authorities in detail, or even to distinguish new matter from old, or contributions of this office from those made by numerous other workers in this field. I have, however, compensated for this deficiency as well as I could by printing a list of the species discussed, with fairly full bibliographical references to the economic literature of each.
