Elonus nebulosus LeConte ; Casey, 1895: 776; Pic, 1896: 50; Werner, 1990: 230; Werner, 1992: 257 Hylophilus (Elonus) nebulosus LeConte ; Pic, 1902: 9; Pic, 1905: 237, 273; Pic, 1910: 12

Type locality. United States, Pennsylvania.

Distribution. Canada (Quebec), United States (Florida to Texas, north to Michigan) ( Werner, 1992).

Notes. Easily separated from all other North American species by its coloration pattern and the enormous size of the male femora. The banding pattern of the elytra tends to fade on very old museum specimens and older specimens should be examined closely to avoid confusion.
