1918] Chamberlin—New Polydesmoid Diplopods 123 
last three acutely produced in increasing degree. Carine all 
depressed. 
Head smooth and shining. Vertigial sulcus distinct, ending be- 
tween antenne often in a weak pit-like depression, a more obscure 
sulcus running from here to each antenna, the two forming a very 
obtuse angle. No occipital foveole detected in types. 
In the male the genital processes of the second coxe are short 
and cylindrical. The sternites are without processes excepting for 
low paired rounded bulgings on the third, fourth, and fifth somites. 
Coxee unarmed. 
The gonopods of the male are strongly pilose with long hairs on 
the mesal side at base, while the coiled blade is more sparsely pro- 
vided with very short hairs. The blade of each gonopod curves 
ventrad and then across the other one, again bending dorsad and 
then back toward its own side as far as the middle line where it 
curves again ventrad at its tip; it narrows gradually distad, becom- 
ing slender, but near the end expands a little into a slightly lanceo- 
late head which is acute and at the base of which on the concave 
side is a short tooth or spine; it is flattened throughout. The basal 
spine is rather stout and somewhat flattened with the acute apex 
bent at right angles to the main axis, and in some showing also a 
small acute point in line with the latter. 
The males are ordinarily obviously smaller than the females. 
Length of type (male) about 34 mm.; width, 7.25 mm. Length 
of a female near 40 mm., with the width 9 mm. The maximum 
male is 41 mm. long and 8.5 mm. wide. 
Locality: East Tennessee; Burbank. Numerous specimens col- 
lected by Dr. R. Thaxter. 
Fontaria ochra sp. nov. 
The types are in general fulvous, with the legs and antennz 
yellow, in most somewhat darker across the anterior region of the 
somites, though in the darkest individual of all the darkest part of 
the somite is in a narrow stripe slightly in front of the caudal 
margin. The general color appearance is much like that of F. 
crass*cutis Wood. ‘The carinz in some are somewhat paler than 
the intervening region. 
Body obviously narrowed at both ends, the sides over most of 
the length being parallel or nearly so. Lateral carinze moderately
