Head and antennae varying from dull yellow to dusky brown, fur- 

 nished with rather long, curving, distant, black, bristly hairs. Pro- 

 notum of the color of the head, but more or less mottled with black- 

 ish, a little broader than long, supplied with long, bristly black hairs, 

 its anterior two-thirds with a distinctly impressed median line. 

 Tegnrina brownish yellow, the upper third of lateral field Avith a 

 blackish bar; the dorsal field often with black fleckings; the mottled 

 appearance sometirnes due, however, to the black of dorsal surface 

 of abdomen shining through them; those of the male rather ample 

 and reaching the tip of the abdomen, those of the female covering 

 but half of the abdomen; wings wanting. All the legs dull brownish 

 yellow, more or less mottled with blackish; the tibial spines pale near 

 the tip. Dorsal surface of abdomen of female with its basal two- 

 thirds black; the last two or three segmenis brownish yellow with a 

 sprinkling of small black spots. Cerci brownish, very slender, as 

 long as the abdomen; ovipositor dark brown, a little upcurved, mod- 

 erately stout, shorter than the hind tibiae, the apical denticular field 

 longer than usual and nearly equaling one-fourth the entire length 

 of the ovipositor. 



Measurements: Length of body, male, 7 mm., female, 8.5 mm.; of 

 tegmina, male, 4.2 mm., female, 3.5 mm.; of hind femora, male, 5.3 

 mm., female, 6.2 mm.; of ovipositor, 3.8 mm. 



This prettily marked little species has been found to be rather 

 common on the grass covered banks of streams and along the fence 

 rows of open woods in Vigo, Putnam and Monroe counties, and it 

 probably occurs in like situations throughout the State. In general 

 appearance it is a diminutive form of N. maculatus above described, 

 but its small size and short arcuate ovipositor at once distinguish it. 

 According to Scudder, carolinus ranges from New England to Ne- 

 braska and Texas.

Size, small; the body of male especially short and broad. Head 

 tumid; eyes large, b^^t not prominent. Pronotmn one-third broader

 bristles, as are also the forehead and dorsal surface of the two front
