156. PAROXYA ATLAXTICA Scudder, 1877b, 29. Atlantic Locust. 



Size small for the genus, the sexes more equal in size than in the 

 other species. Metazona, tegmina and upper and outer faces of all the 

 femora of male a uniform light wood-brown, occiput and prozona darker. 

 A. broad black stripe extends from the eye along the upper half of the lat- 

 3ral lobes of pronotum as far as the posterior transverse sulcus, where it 

 merges gradually into the paler brown, this black stripe bordered below 

 by one of ivory white, brightest on the head, and often flecked with fus- 

 cous dots; metapleura also ivory white. Face grayish-olive, flecked or 

 tinged with yellowish; basal two-thirds of antennae the color of tegmina, 

 apical third usually darker. Palpi and prosternal spine yellow. Sternites 

 of thorax olive brown; those of abdomen yellow, as are also the lower faces 

 of all the femora. Hind tibia? dull pale green ( basal third sometimes light 

 brown), with a black spot at knee; the spines with their apical thirds 

 black. Female darker, discoidal area of tegmina sometimes obscurely and 

 sparingly flecked with fuscous, the yellow of under side dull or wanting. 

 Prozona one-third longer than metazona, the latter with hind margins ob- 



tuse-angulate. Supra-anal 



plate of male very short, tri- 

 angular, with a short basal 

 triangular sulcus, in which 

 rest the furcula; these con- 

 sisting, in northern individ- 

 uals (scudderi Blatch.), of a 

 pair of flattish, oblong plates 

 with their inner edges paral- 

 lel and tips rounded ; in the 

 southern ones (typical atlan- 

 tica) they are subtriangular 

 with the tips narrow and 

 feebly diverging. Cerci long, 

 slender, strongly incurved, 

 narrowed at middle, the basal 

 half stouter, apical third flat- 

 tened, feebly concave and

In Indiana this graceful-bodied species was first found in 

 small numbers on July 27, about the grassy margins of a pond 

 in the sand dune region north of Millers, Lake County, and with- 

 in one-half a mile of the shore of Lake Michigan. On the fol- 

 lowing day a single pair were taken from a similar locality near 

 Tolleston, in the same county, and about four miles from the lake,
