NEW POLYDESMOID DIPLOPODS FROM TENNESSEE 
AND MISSISSIPPI. 
By Raupu V. CHAMBERLIN, 
Museum of Comparative Zoélogy. 
Of the following underscribed species of millipedes one was 
collected in Mississippi at Agricultural College by Mr. J. W. Bailey, 
while the other four, three of them pertaining to a new genus, were 
taken by Professor R. Thaxter at Burbank in eastern Tennessee. 
The new genus is segregated from Fontaria sens. lat. 
Fontaria pela sp. nov. 
This species when in full color is above deep shining black with 
the caudal corners of the carinz and the tip of the last tergite in 
life apparently bright red, fading in alcohol to brown or orange. 
There may or may not be a narrow stripe of the same bright color 
across the anterior border of the first tergite. The lateral region 
of each somite is in the main reddish or orange brown with a black 
stripe down the caudal portion from carina to legs, and a less dis- 
tinct dark stripe in some along the anterior border as well. The 
antennz are somewhat chestnut and the legs are brown. 
The body is proportionately rather slender. - It is parallel-sided 
excepting at the ends which are narrowed. The lateral carinz are 
moderate in size; the caudal margins of the anterior ones are bent 
forward, those of the middle region less so, and those of the posterior . 
ones first straight and then bent caudad, the posterior angles of the
