ORTHOPTEEA OF INDIANA. 177 



in texture, quite flat, the former nearly semi-orbic'ular in shape, much 

 the broader in the female, the hind border a little rounded in the 

 male, truncate in the female. Tegmina fully developed and much 

 surpassing the abdomen in the male (of our species); abbreviate and 

 with the apex obliquely truncate in the female. Abdomen very flat 

 above, convex beneath. Supra-anal plate of the male, transverse, 

 rounded; that of the female triangular. Sub-genital plate of the 

 male, narrow, bearing two stylets; the one on the left usually the 

 larger. Cerci rather long and stout, 10-jointed. Last ventral seg- 

 ment of the female abdomen broadly rounded, entire. 



As noted above, I consider that certain species heretofore ascribed 

 to this genus are females of species of Ischnoptera. This eliminates 

 the nominal species T. major Sauss.-Zehnt. and T. virginica Brunn. 

 of Scudder's Catalogue, representatives of which occur in Indiana, 

 and leaves T. deropcltiformis Brunn. as our sole representative of the 

 genus.

TinnnG2)frnj.r di'ropdt{fornii>i Brann., 37, 1865, 87; Bl., 8, 1893, 160. 



Main characters as given above. Disk of male pronotum 

 with three impressions, one shallow, median and longitudinal, the 

 other two deeper, semicircular and lateral. Tegmina of female cov- 

 ering about one-third of the abdomen, their inner edges meeting; 

 those of male much surpassing the abdomen. 



Color, a uniform dark mahogany brown, except the tibias and tarsi 

 of all the legs, which are a light reddish brown, the contrast between 

 the two colors, in living specimens, being very striking. Wings of 

 male transparent, slightly infuscated, the veins and anterior border 

 light brown. 



Measurements: Length of body, male, 14 

 mm., female, 15 mm.; of pronotum, male, 3.5 

 mm., female, 4.5 mm.; of tegmina, male, 15.5 

 mm., female, 5 mm.; width of pronotum, male, 

 4.5 mm., female, 6 mm. 



In Indiana this handsome roach has, as yet, 

 been noted only in Vigo and Crawford coun- 

 ties. In the former it was found in but one 

 locality, the border of a marsh in a low sandy ^'f'.^^' '^^^''^opteryx de-

woods three miles east of Terre Haute. A male one and one-third 

 single pair were taken on May 28, 1893, and on "■""' natural size.

June 18, probably a dozen specimens were se- 

 cured. They were hiding beneath small logs and sticks, and the 

 males, when deprived of their shelter, flew actively away, while the
