Judging by the intensity of the infestation in L917 and by the size of the area infested m( time, as well as from the reports concerning the activity ni" the pest prior t L917, Vinal was .,1' the opinion that it had been imported about 1910, although realiz- ing that this was only a conjecture. The investigations since L917 have indicated that final's estimate was probably very nearly correct, although the exact date is >iill unknown. In L916 specimens of dahlia stems infested by lepidopterous larvae uciv sent to the Massachusetts Agricultural Experiment Station from three localities near Boston, Mass. Adults were reared from this material, bul their identity as /'. wubUaUa was not established until after adults had been reared from sweet corn by Vinal in L917, At the end of L924 a total of 5,661 square miles was known to be infested by the European corn borer in tin- eastern New England area (see map, fig. I), as shown by Mr. Worthley's field scouts, including eastern Massachusetts, the adjoining portion of New.
