The young, which are sometimes noticed as early as the latter 
part of August, are curious little, depressed, toad-like creatures of 
a purplish-leaden color, and may be found, under suitable condi- 
tions of weather, in the fall, winter, and early spring months in 
localities frequented by the adults. 
The Coral-winged Locust probably occurs throughout New 
England, having been taken on the summits of Mt. Katahdin and 
Mt. Washington, on Nantucket Island, in southern Connecticut, 
and many intermediate localities; it is also widely distributed 
beyond our borders.

Head full, rounded, occiput very convex; vertex short, strongly 
declivent, smoothly rounded into face, its scutellum convex, 
divided into four parts by low carinae running outward and back- 
ward from middle of median carina. Prozone equal to metazone, 
strongly rugose; disk of metazone coarsely tuberculate, the hind 
process rectangulate or a little obtuse. Lateral lobes deeper than 
long, the hind angle very broadly rounded. In size this species is 
somewhat less than its congener, the Coral-wing. 
Pale brown or clay color, the tegmina heavily and irregularly 
spotted with fuscous. Hind tibiae clay yellow, sometimes 
clouded near the middle with dusky. Disk of wings yellowish 
white, yellow, pinkish, or vermilion, covering one-half to four- 
sevenths of the wing, bounded by a narrow fuscous band from 
which near the costal margin extends a shoot one-half or two- 
thirds the distance toward the base. Beyond this the wing is 
transparent, the veins heavily infuscated, the tip often clouded. 
Hind thighs obliquely fasciate with fuscous externally. Face 
usually nearly immaculate; crown of head streaked, and disk of 
pronotum more or less fuscous, with a pale X-mark; dorsal and 
lateral fields of tegmina separated by a pale line broadening poste-
