a character not to be relied upon as specific or even varietal difference* ; " 

 yet Redtenbacher in his Monographic der Conocephaliden has separated 

 a number of his species by this character alone, and I can find no men- 

 tion in his work of the fact that such a variation exists. 



66. Ovipositor a little curved ; tegmina constant in length, covering 

 about two-thirds of the abdomen in the male ; shorter in the 

 female.

 A rather robust species with the general color a dark, greenish brown ; 

 tegmina light reddish brown with the front or lower area fuscous. Dor- 

 sal stripe of occiput and pronotum not contrasting so strongly with the 

 general color as in the preceding species, margined with a narrow yellow 

 line on each side. All the femora punctate with reddish dots, the tarsi 

 and tip of hind femora dusky. Tegmina with the veins and cross veins 

 unusually prominent giving them a coarse and scabrous look ; the tympa- 

 num of male stout and elevated. Cerci conical, the apex obtuse, but lit- 

 tle compressed. Ovipositor as long as the abdomen, the apical half with 

 a gentle but evident upward curve. 



Measurements : Male — Length of body, 14 mm. ; of tegmina, 8 mm. ; 

 of hind femora, 12 mm. ; of pronotum, 3.5 m. Female— Length of body, 

 15 m.m. ; of tegmina, 5.5 mm. ; of hind femora, 13 mm. ; of ovipositor, 9 

 mm. 



Redtenbacher, in his Monographie, has evidently described this species 

 as new under the name of curtipemu . His specimens were from Missouri. 

 Nemorale is a very common insect in Vigo and Putnam counties but has 

 not as yet, been taken in the northern part of the State. It reaches ma- 

 turity about August 1 5th and from then until after heavy frosts may be 

 found in numbers along the borders of dry, upland woods, fence rows, and
