before us, those of cinnamon coloration having in ahnost every case 

 been taken in the undergrowth of the pine woods. 



The coloration of the specimens here described is as follows. Occi- 

 put and vertex mars brown; face shining piceous, sharply delineated 

 from the vertex by a paler edging of the latter and crossed by a very 

 striking but narrow supra-ocellar band; post-ocular region pale 

 russet. Maxillary palpi with proximal segments cinnamon, terminal 

 segment dark, shading abruptly from cinnamon to clove brown in the 

 proximal fifth. Pronotum mars brown with ventro-caudal angle of 

 lateral lobes clove brown, the immediate margin at this point very 

 pale. Dorsal surfaces of limbs russet, flecked with darker brown; 

 external face of caudal femora, however, strikingly marked with two 

 narrow longitudinal bands of clove brown tinged with tawny. Teg- 

 mina of male shining piceous, discoidal vein cream color, which 

 coloration is continued as a narrow distal border to both dorsal and 

 lateral fields, thereby giving the insect a very trim appearance; of 

 female shining piceous, the intermediate channel buffy. Dorsal 

 surface of abdomen of male clove brown tinged with tawny; of 

 female mars brown, that portion hidden by the tegmina piceous in 

 both sexes. In both sexes the ventral surface of the body and limbs 

 is cinnamon. 



A number of females before us have the entire dorsal fields of the 

 tegmina of the same paler coloration as the intermediate channel 

 and in such specimens this surface is usually flecked with darker 

 brown. Some specimens have the lateral lobes of the pronotum 

 unicolorous, dark or light brown, and the pale coloration of the 

 margin of the ventro-caudal angle is often much reduced or entirely 

 absent. In a very few of the palest colored specimens the striking 

 markings of the external faces of the caudal tibiae are absent. The 

 striking cephalic markings are always distinct and are an excellent 

 specific character. 



Distrihution. — The present species is known to range from Florence, 

 South Carolina, and Gwinnett County in northern Georgia, south- 

 ward over that State and throughout the mainland of Florida. 



Biological Notes. — Allard states that the present species is the first 

 to appear at Thompson's Mills in north Georgia, and describes its 

 song as a very brief, high-pitched, and shrill "tiiiiiiii-tiiiiii-tiiiiiiiii- 

 tiiiiiiii." He further remarks, ''It is one of the commonest species 

 of Nemobius in this vicinity and begins to stridulate as soon as spring 

 opens in March and April. In April, 1910, very cold periods of 

 weather with considerable sleet and snow completely silenced these
