General dorsal color varying from clay color to prout's brown, 

 pronotal maculation and general suffusion of tegmina varying from 

 raw umber to clove brown, pronotal disk occasionally much darker 

 than tegmina; discal maculation of pronotum with lateral margins 

 sinuate, in some cases reaching, in others not reaching, cephalic 

 and caudal margins, lateral portions subhyaline to opaque buff. 8 

 Head clove brown or with face alone that color or vandyke brown ; 

 supra-ocular spots dull yellow ; antenna same as general color. Teg- 

 mina with costal margin, particularly of costal field, pale, usually sub- 

 hyaline; humeral trunk darker than any other portion. Wings slightly 

 infumate. Abdomen varying from tawny-olive to bistre, on the venter 



usually paler laterad and mesad. Limbs varying 



\~/* ^\F^ ^ith general coloration, spines darker.

subequal to or \-eiy slightly wider than that 



between antennal scrobes; antennae very slightly longer than body. 



Pronotum considerably broader than long, lateral and cephalic margins 



arcuate, slightly subtruncate meso-cephalad, very slightly oblique 



subtruncate laterad, caudal margin subarcuate to arcuato-truncate, 



caudo-lateral angles rounded obtuse-angulate; disk moderately 



deplanate, declivent laterad. oblique sulci hardly indicated. Tegmina 



from two to two and one-half times length of pronotum, greatest 



width subequal to pronotal length : costal margin regularly arcuate, 



apex obliquely rotundato-subtruncate; costal field moderately 



broad, rather short, costal veins regularly oblique subparallel, anal 



sulcus reaching to slightly proximad or distad of middle of sutural 



margin. Wings either distinctly shorter than tegmina or reaching 



to tips of same; ulnar vein with four to five complete and one to two 



incomplete rami. Supra-anal plate trigonal, the apex acute, 9 more or 



less distinctly carinate medio-longitudinally; cerci depressed sub- 



ensiform, acute. 



General color varying from tawny-olive to mummy-brown, pronotal 



8 Rarely the pale lateral portions are reduced to mere lines and in two cases 

 the disk has a paler medio-longitudinal line. 



9 In one specimen (Marion County, Ind.) it is blunter than in the others, but 

 the length of tegmina, form of pronotum and general appearance seems to indicate 

 its proper place in this species.
