. Ectoparasites of the cottontail rabbit in Lee County, northern Illinois . Fig. 6.—Ixodes Jentatus, eastern rabbit tick, unenfjorged adult female. Adults of this species may be distinguished from adults of the other rabbit ticks in Illinois by the relatively long mouthparts (palps, indicated by arrow) and lack of scal- lops (festoons) around the posterior dorsal margin of the body. Determination of the immature stages can be made by using the key published in Cooley & Kohls (1945).
