1918] Chamberlin — Neiv Polydesmoid Diplopods 1^3 



last three acutely produced in increasing degree. Carinse all 

 depressed. 



Head smooth and shining. Vertigial sulcus distinct, ending be- 

 tween antennse 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 foveolse detected in types. 



In the male the genital processes of the second coxse are short 

 and cylindrical. The sternites are without processes excepting for 

 low paired rounded bulgings on the third, fourth, and fifth somites. 

 Coxse 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. no v. 



The types are in general fulvous, with the legs and antennae 

 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 carinae 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 carinse moderately
