THE ROUGH-HEADED CORN STALK-BEETLE 3 DISTRIBUTION The known distribution of Euetheola rugiceps in the United States is shown in Figure 1. The data upon which the map is based were obtained from the literature, from hitherto unpublished field records and correspondence of the bureau, and from personal correspondence with a number of museum and experiment station Euetheola rugiceps is recorded from all the Southern States lying south of the latitude of Washington, D. C, with the exception of Florida and Oklahoma. Judging by the erratic manner in which the species has been observed to occur in the infested sections of Virginia, it would be inadvisable to draw final conclusions regarding the limits of distribution from the evidence at present available. In Virginia the species was found only in that part of the coastal plain which lies between the Potomac and James Rivers, apparently preferring low. moist, poorly drained soils. Even within the area thus restricted, the spe- cies appears at present to be of very unequal distribu- tion, being abun- dant in certain lo- calities and rare or absent in others. It may be found swarming in certain fields, utterly de- stroying the corn crop, while other fields of the same general type less than a mile away appear to be uninfested. Doubt- less there are unknown factors which influence and limit the spread of this species. The following is a list of localities, arranged according to States, from which there are records of the occurrence of the species. Alabama.—Birmingham, Catherine, Carollton, Cleveland, Eutaw, Hampden, Hartsells, Mobile, Sprott. Arkansas (by counties).—Ashley, Bradley, Clark, Crawford, Cross, Hot Springs, Howard, Jackson, Jefferson, Lincoln, Lonoke, Monroe, Nevada, Perry, Pope, Pulaski, St. Francis. Georgia.—Bainbridge, Canton, Dalton, Macon. Kentucky.—Guthrie and Hartford. Louisiana.—Atchafalaya River, Baldwin,
