 equal; form robust. Dull grayish- or reddish-brown above, clay-yellow be- 

 low, the male the darker. Antennae reddish-brown, paler at base, dusky 

 toward tips; occiput and disk of prozona fuscous; the usual black band 

 behind the eye, extending back to metazona and bordered below by green- 

 ish-yellow. Tegmina dull reddish-brown, with often a few small fuscous 

 spots on discoidal area. Hind femora dull brownish-yellow with two broad 

 oblique blackish bars on upper, outer and inner faces; lower face pale or 

 dull red; knees black; hind tibiae red, rarely pale green, with a lighter 

 ring near base, spines black. Occiput distinctly elevated above the prono- 

 tum; interocular space as broad, male, or nearly twice as broad, female, 

 as basal joint of antennae, fastigium strongly declivent, shallowly sulcate, 

 its lateral margins distinct, male, very low, female. Frontal costa as 

 broad as interocular space, feebly sulcate below the ocellus, male, slightly 

 concave around it, female. Pronotum feebly expanding on metazona, disk 

 rounded on prozona, flat on metazona; hind margin broadly rounded or 

 obtuse-angled; median carina distinct only on metazona, faintly visible on 

 portions of prozona. Tegmina usually covering two-thirds, female, or 

 three-fourths or more, male, of abdomen, sublanceolate, their inner edges 

 overlapping. Cerci of male straight, about four times as long as broad, 

 middle third but slightly narrowed, apical third concave or sulcate, with 

 tip rounded and incurved (Fig. 139, a.) Supra-anal plate broad, triangular, 

 apex subacute, margins elevated, median ridges extending from base three- 

 fourths to apex, at apical third uniting with a cross carina which, with 

 the ridges, form on the basal two-thirds of the plate a narrow median sul- 

 cus and two broad lateral concavities; furciila consisting of a pair of 

 minute, widely separated subcylindrical projections lying outside the me- 

 dian ridges (PI. Ill, g.) Subgenital plate longer than broad, the apical 

 margin well rounded, feebly elevated at middle. Length of body, $ ,

Wineliendon and Sherborn, Mass. (Morse] ; Lake and Marshall 

 Cos., Ind. (Tr. AS'. /*.) ; Big Horn Mts., Wyo. This small locust 

 has been taken in Indiana only in Marshall, Tippecanoe and Lake 

 counties. In Marshall Co. it has been noted only in a low sandy 

 oak woods, bordering Lost Lake, and just west of the station of 

 Arlington at Lake Maxinkuckee. Here among low huckleberry and 

 other bushes it is common from July 15th on, the females, however, 

 far outnumbering the males. Koth sexes leap vigorously when dis- 

 turbed, but often squat close to the ground after being flushed 

 once or twice. Tn Lake County a few specimens have been taken
