SUP-FAMILY I. TKYXALIXJE. 229 



the median row of spots smaller, fewer in number, often wanting; dark 

 bar behind eye more faint than in pclidiia, seldom crossing onto the meta- 

 zona; hind femora greenish or brownish, not banded; hind tibiae dull 

 brown or yellowish, without paler ring near base. Vertex broader and 

 blunter than in pelidna, the margins scarcely raised above the disk, often 

 with a faint median carina on its front half, the central depression close 

 to apex (Fig. 84, i.) Antenna? about as long as head and pronotum, plainly 

 flattened, the middle segments nearly twice as long as broad, the apical 

 fourth tapering. Median carina of pronotum cut slightly behind the mid- 

 dle by the principal ^ sulcus. Tegmina usually reaching tip of abdomen, 

 female, tip of hind femora, male, often shorter. Length of body, $ , 13 15,

 1116; of hind femora, $, 9 10, $, 10 12 mm. 



Of tin's species, usually abundant where found, only three 

 specimens have been collected by me in Indiana, and it is known 

 from only three locations in the State. A male and female were 

 taken July 25 from the side of a railway a mile southeast of Ham- 

 mond, Lake Co., and a single male near Bass Lake, Starke Co., 

 Aug. 30. Fox (1915, 22) records the taking of four specimens near 

 Lafayette from dry, open, grassy tracts on unfilled land. Its 

 scarcity in Indiana is strange as Hart (1907, 231) states that it is 

 found in "all Illinois, especially on dry soils; taken at light." 



The records of the species show its known range to extend 

 from New England, where it is apparently very common, north 

 and west to Toronto, Ont., 38 Minnesota and western Nebraska, and 

 south and southwest to Virginia, Shreveport, La., northern Ala- 

 bama, and northwestern Arkansas, where McNeill (1899, 53) men- 

 tions it as occurring only in a few widely scattered localities. In 

 northern Illinois he found it confined to the tops and sides of 

 hills. Morse calls it "a northern offshoot of an austral genus 

 adapted to more boreal conditions," and has written of it (1890, 

 410) as reaching maturity in New England the first week in July, 

 and being "one of the most plentiful and wide-spread of our lo- 

 custs, but owing to its small size and non-migratory habits, it does 

 not attract the attention given to the larger and consequently 

 more destructive species. While somewhat local, it is found nearly 

 everywhere on dry, sandy or loamy soils. It moves chiefly by 

 leaping, but readily takes wing on occasion, flying, however, but a 

 few feet. Active and alert in the hot, sunny weather of mid-sum- 

 mer, it can best be secured by sweeping the net rapidly over the 

 ground, a dozen or more specimens being the result of a few 

 minutes work." 



38 Scudder (1899, 184) records it from Nova Scotia on the authority of Piers, but the 

 latter author (1918, 265) says there is no known definite record of its occurrence in that 

 Province.
