In 1896 Prof. J. T. Stimson recorded injury caused by this insect in Arkansas. Dr. John B. Smith, in his Catalogue of Insects of New Jersey, 1900, reports its occurrence throughout that State. Dr. L. O. Howard reported it from Bloomington, 111., in 1901. In later years the insect appeared as a pest in the grape region of Penn- sylvania and New York, where from 1900 to 1906 it was the subject of detailed studies, treating both of its life history and remedial measures, by the late Prof. M. V. Slingerland, of Cornell University,. Fig. 1.—Map showing distribution of the grape root-worm {Fidia vilicida). (Original.) and by Dr. E. P. Felt, state entomologist of New York. The reports of the investigations by the former are embodied in the bulletins of the entomological division of Cornell University, and the publica- tions of the New York State Museum contain reports of those made by the latter; all publications of these two investigations are listed in the bibliography accompanying this bulletin. ORIGIN AND DISTRIBUTION. The grape root-worm has at present been recorded only from North America, and it is without doubt a native species, feeding originally on wild grapevines, as it still does to some extent. The insect is widely distributed in the Mississippi Valley and in the Eastern States. The map (fig. 1) shows the distribution as recorded at Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the origi
