Size medium for the genus, form robust. Male. Grayish or fuscous- 

 brown; sides of pronotum and tegmina blackish, the former often shining, 

 especially in the young; lateral lobes with a narrow curved yellowish line 

 along the hind margin; exposed dorsal field of tegmina light brown; fe- 

 mora with numerous minute pale spots. Female. Usually grayish or red- 

 dish-brown throughout, except the yellow line on side of pronotum, which 

 is bordered above with a dash of black. Head large, set into pronotum al- 

 most to eyes. Antennae slender, less than twice as long as body, the basal 

 segment strongly flattened, about as wide as fastigium. Pronotum with 

 disk large, its greatest width about two-thirds its length; lateral carinse 

 sharp, distinctly converging from base to apical fifth, then feebly diverging 

 to apex; hind margin broadly rounded or subtruncate; lateral lobes with 

 hind margin long, sinuous, very oblique. Tegmina of male exposed a dis- 

 tance at least equal to greatest width of pronotum, often more, their tips 

 broadly rounded. Cerci of male subcylindrical, stout, tapering, feebly 

 curved, rather bluntly pointed, the tooth at inner apical third short, blunt; 

 apex of subgenital plate broadly shallowly emarginate; styles short, ob- 

 tuse. Ovipositor straight, about as long as hind femora, its apical sixth 

 tapering above to the acute tip. Length of body, $, IS 24, 9, 19 25; of 

 pronotum, $, 910.8, 9, 8.810.4; of tegmina, $, 79; of hind femora, $,

 notum, $, 6.37.8, 9, 6.17.3 mm. (Fig. 196.) 



This bulky brown Ortliop- 

 teron occurs throughout In- 

 diana but is more common in 

 the northern counties. It fre- 

 quents for the most part dry 

 open woodlands, thinly wood- 

 ed rocky slopes and borders 

 of thickets, where it crawls

slowly over the fallen leaves 



being very clumsy in its movements. The earliest date on which 

 a mature specimen has been noted was June 6th, in Vigo County, 

 numerous specimens being taken between that date and June 20, 

 while they may be found until after heavy frosts. 



The general range of A. testaceus is northern, it being the 

 most common Atlaiiticus north of the Ohio and east of the Mis-
