There are two subspecies of Neocicada hieroglyphica: Neocicada hieroglyphica hieroglyphica (Say, 1830) and Neocicada hieroglyphica johannis (Walker, 1850). According to Wm. T. Davis, a key difference is: on N. hieroglyphica johannis, “the black marks on the head, pronotum and mesonotum are more in the form of spots than of continuous lines as in typical hieroglyphica”.

A description by Wm. T. Davis from MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES1:
Cicada hieroglyphica Say.
Occurs from Riverhead, Long Island, N. Y., to eastern Kansas and southward. In peninsular Florida the variety johannis Walker replaces the typical form. The black marks on the head, pronotum and mesonotum are more in the form of spots than of continuous lines as in typical hieroglyphica.
The song does not continue long, but sometimes, as in the Pine Barrens of New Jersey, the insects appear in numbers, when their united effort produces a considerable noise.
Neotibicen tibicen tibicen (Linnaeus, 1758) aka Swamp Cicada or Morning Cicada. Morning because it sings in the morning. There is another sub-species of Neotibicen tibicen names Neotibicen tibicen australis. The key difference between the two is australis has a mostly green collar, while tibicen’s collar is black.
Description: Swamp Cicadas are are known for their rounded, humped back. Their coloration varies from mostly black & some green to black, brown and green. Their collar is usually black, but can include green.
Description: The Scissor Grinder looks a lot like Linne’s Cicada but their wing doesn’t have bend that Linne’s Cicada has. The Scissor Grinder also seems to have more of an orange coloration to the ‘arches’ on its mesonotum.
The song of pruinosa is quite unlike that of any of the other large native cicadas, and may be rendered as z-zape, z-zape, z-zape. The insect often remains quiet all day, singing from about 3 or 4 P. M. until dark.
Identification Key by Wm. T. Davis:1
A. Large, heavy bodied species ; head broad, uncus simple, and first cross vein in the fore wings starting from radius 3 far back, or about one third distant from base of first marginal cell.
B. Uncus longer than broad. Black species with green or greenish markings and black area on the central part of the abdomen beneath
C. Hind margin of pronotum or collar, green or greenish.
A narrow irregular area of black on the under side of the abdomen; opercula short and broad, and usually in the males an attenuated, pruinose stripe each side on the dorsum of segment three.
