Color Notes. — The contrasting and solid coloration given in the 

 description is distinctive and varies but little in tone in the series. 



Distribution.- — The insect is known only from Thomasville, in 

 southwestern Georgia. 



Biological Notes. — The series was taken near the town in a small 

 area of moist ground where the pine woods gave way to the magnolias 

 and beeches of the "branch" forest growth. All of the specimens 

 were captured in sphagnum growing among the roots of these latter 

 trees. The entire series is brachypterous. 



Specimens Examined. — 13: 5 males, 8 females.

Subgenus EUNEMOBIUS n. subgen. 



This distinctive subgenus includes two species and two geographic 

 races from North America. Type of subgenus — Nemohius carolinus 

 Scudder. 



Suhgeneric Description. — Size medium for the genus. Disto-- 

 ventral spurs of caudal tibia equal in length. Proximal and distal 

 internal spines of male specialized as described under Morphological 

 Notes for the genus; other spines of caudal tibia below concave, with 

 margins of this sulcation smooth in both sexes. Ovipositor very 

 short, almost always less than two-thirds the length of the caudal 

 femur, gently curved; apex with dorsal margin armed with heavy 

 teeth, ventral margin armed with minute, widely spaced serrulations. 

 Ventral segments of abdomen in male broadened, extending outward 

 and upward on sides of abdomen above the normal dorsal segments, 

 thus making the abdomen unusually broad and its entire dorsal 

 surface concave. 



The present subgenus is widely separated from the other North 

 American subgenera by the majority of the characters given above.
