A very distinct and well marked species ranging from Beach 

 Haven, N. J., through North and South Carolina to southern Geor- 

 gia, its distribution being erratic and discontinuous. Morse (1004, 

 27) records it as occurring on wet ground near a stagnant pool 

 at Denmark, S. Car.; while K. & H. state that it "prefers areas 

 in pirie woods of low black, water-soaked ground covered with 

 low bog plants," though sometimes found in wet meadows in com- 

 pany with Tcttiyidca lotcralis and Paxilla obcsa. It appears to 

 be a rare species wherever found, no more than three or four in- 

 dividuals being recorded from any one locality except at Homer- 

 ville, Ga., and Yemassee, S. Car., w r here 16 and 59 were respective- 

 ly taken. To the long form the name elonyata was given by Morse 

 (1805, 16). 



79. TETTIGIDEA ARJIATA Morse, 1895, 107. Armored Grouse Locust. 



Form usually longer and more robust than in T. lateralis, notably so 

 in the females. Color dark gray or brown above, blackish on sides, the 

 tegmina with a white spot on their apical third; hind femora usually 

 more or less mottled with whitish on their outer face. Vertex but little 

 projecting beyond front of eyes and scarcely wider than one of them; 

 frontal costa, viewed from the side, prominent, its sulcus very narrow. 

 Pronotum as described in key, its median carina distinct, sharp, nearly 

 horizontal, its dorsal surface strongly roughened with rather' long wrin- 

 kles, the sides in front of the shoulders a little excavated; hind margins 

 of lateral lobes strongly bisinuate, tegminal sinus deep, acute, lower one 

 broad, shallow, the lobe between them short, rounded. Tegmina elongate- 

 oval, their tips subacute. Wings in long form slightly surpassing the tip 

 of pronotum, which extends 2 to 3.5 mm. beyond tips of hind femora; in 

 short form the wings shorter than pronotum, the latter reaching only to 

 base of ovipositor in female. Length of body, $, 8.512.8,; 5, 11.517; 

 of pronotum, $, 7.511.5, 9, 11.516; of hind femora, $, 5.56, 9, 

 7 8 mm. 



This grouse locust occurs sparingly throughout Indiana, adults 

 being found from April to November. Morse's types were taken 

 by me in Vigo County, where it occurred in small numbers along 



o 



the wooded margin of a large lowland pond. In the northern 

 counties it frequents woods about tli<> margins of lakes and is 

 usually found closer to water than is T. latcralis. In Florida it 

 has been definitely recorded only from Jacksonville, Monticello 

 and Deep Lake, April Oct. R. & H. (1916, 153) give its range as 

 extending from "Staten Island, N. Y., south to extreme southern
