brown or yellowish, usually with a row of black dots along the upper and

 yellowish, tipped with black. Vertex rather prominent, narrow; disk sub- 

 rhomboidal, but little depressed, its sides low, distinct only on front half. 

 Face vertical, frontal costa narrow, slightly sulcate below the ocellus, the

 higher and sloping on prozona, hind margin broadly obtuse-angled, surface 

 densely punctate, median carina low but distinct. Prosternal spine large, 

 cylindrical, its apex rounded. Tegmina exceeding the abdomen about one- 

 fourth their length, male, one-sixth, female. Hind femora slender, reach- 

 ing tip of abdomen, female, exceeding it 2 to 3 mm., male. Cerci of male

This species has been taken only in the western half of Indi- 

 ana, from Knox Co. northward, though it doubtless occurs in suit- 

 able environments throughout the 

 State. It is abundant about the 

 marshy meadows and sloughs in 

 Fulton, Lake and Starke counties, 

 where it has been taken on August 

 15th in numbers. There it makes 

 its home in the rank grasses, weeds 

 and rushes which grow in such 

 j daces. The males are everywhere 

 much more abundant and more ac- 

 tive than the females, though they 

 usually fly a shorter distance. In 

 Vigo County it is frequent in 

 patches of raw, damp prairie and 

 along the edges of thickets border- 

 ing them ; also in many places 

 along the railways, especially 

 where they pass through prairie 

 regions. Both sexes, when flushed, 

 arise with a whirring noise which, 

 however, is not a true stridulation. The males usually fly about 

 50 feet and settle down on the grass or on a low shrub. 



I have not so far taken ciJutacea in Florida, but it occurs spar- 

 ingly throughout the mainland of that State, as shown by the rec- 

 ords of K, & H., Morse and Davis. The form found on the south- 

 ern keys is ruMginosa (Scudd.). 



The known range of this typical form of oJiitacea is a very 

 wide one, extending from New England to California, and south
