ORTHOPTEEA OF INDIANA. 317 



the disk feebly convex; median carina visible throiigliout, distinct on 

 metazona; hind margin obtuse angled; the prozona but little, if any- 

 longer than the finely punctate metazona. Tegmina* reaching the 

 tip of hind femora in both sexes, moderately broad and tapering. 

 Extremity of male abdomen but little recurved; the cerci narrow, 

 compressed, straight, the middle third about half as broad as the 

 extreme base, the apical third but little expanded, the tip rounded. 

 Furcula consisting of a pair of short, triangular spines which lie upon 

 the bases of the ridges of the supra-anal plate. Sub-genital plate 

 scarcely longer than broad, sub-conical, terminating in a blunt 

 tubercle. (See Fig. 10, Plate I.) 



Color: Eeddish brown above, yellowish below. Face yellowish 

 brown, dotted with fuscous; occiput and disk of pronotum darker. 

 Antennae reddish, the apical fourth fuscous. An indistinct black 

 band extends from eye back across the upper half of the lateral lobe 

 of prozona; this often nearly obsolete in the female. Tegmina grayish 

 or reddish brown, with a number of dark spots along the discoidal 

 area. Hind femora reddish brown, with two more or less distinct 

 oblique black bars on upper and outer faces; the lower face orange 

 red; the knees dusky. Hind tibia3 bright red, the spines black. 



Measurements: Length of body, male, 18 mm., female, 32 mm.; 

 of antennae, male and female, 8 mm.; of pronotum, male, 5 mm., 

 female, 5.5 mm.; of tegmina, male and female, 15 mm.; of hind 

 femora, male, 11 mm., female, 12.5. 



This is a southern species, heretofore recorded only from Georgia, 

 Mississippi and Arkansas. On July 10, 1902, I found it plentiful on 

 a sandy wooded slope in Gibson County, Indiana, about 10 miles 

 southeast of Mt. Carmel, Illinois, and at a point where the terrace on 

 the Indiana side of the Wabash River meets the sandy uplands. Here, 

 among the scant grass and weeds the insect had found a suitable 

 abiding place. The males take to wing readily when disturbed, but 

 the females seem to depend only on their short hind legs to take them 

 out of sight of their pursuer. Specimens were sent Professor Morse, 

 who kindly verified my determination by comparing them with Scud- 

 der's types. It is probable that the species will be found over most 

 of the sand-covered area of the lower Wabash River.

'■' Scuilder, in his origin<al description, gives them as "surpassing a little (male) or eon- 

 siderahly (female) the hind femora," but this is not true of Indiana specimens.
