NEW XYSTODESMID MILLIPEDS — HOFFMAN 375 



that in wet weather he had seen the millipeds crawling about in the pine 

 stands. 



The locality at which Mr. Carr obtained a large series of speci- 

 mens is at the base of the Blue Ridge, in a moist hardwood forest 

 with many ponds and marshes. 



All the specimens listed above are very large, some attaining a 

 length of 45 mm. The keels are bright reddish pink, and the posterior 

 margins of the keel are marked by broad yellow bands. ]Mr. Loomis, 

 upon examination of a specimen, suggested that Koch's name be used 

 for my material, an allocation with which I gladly concur. The male 

 gonopods of the specimens are identical with those of many large, 

 cross-banded Aphelorias from Ohio, West Virginia, and Pennsylvania. 

 The status of the banded Aphelorias is confused, and some hesitation 

 attends my identification of some of the Virginia material. A thor- 

 ough revision of the genus, based on adequate series of specimens, is 

 much to be desired. 



APHELORIA KLEINPETERI, new species 



Plate 26, Figures 3, 4 



Diagnosis. — A medium-sized species characterized by the color pat- 

 tern of black dorsum and red keels and by the structure of the male 

 gonopods, the telopodite of which is expanded distally into a spatu- 

 late portion suggesting that of Sigiria,. 



Description. — Length of holotype, 37, width, 7.2 mm., length of 

 allotype, 39.1, width, 8.1 mm. Width of body averages 20 percent of 

 length. Segments between fourth and fifteenth of full width. Keels 

 moderately broad, not overlapping. Anterior corners lobed, rounded ; 

 posterior corners through twelfth segment approximately right- 

 angled, becoming caudally produced on the posterior third of body. 

 Keels of segment 18 almost enclosing those of 19. All keels with dorso- 

 lateral edges raised, particularly so on last 10 segments; repugnatorial 

 pores on dorsal side of swellings. 



Collum crescentic in shape, as long as the next two segments com- 

 bined, its posterior edge with a median emargination, ventrolateral 

 extremities directed slightly caudoventrad. 



Anal segment triangular in dorsal aspect, longer than broad, base 

 slightly wider than distance between keels of penultimate segment; 

 end truncate, bearing a few setae. Anal valves slightly inflated, gla- 

 brous, their mesial edges produced into ridges each of which bears a 

 single setiferous papilla. Each valve with a small knob near the center, 

 otherwise unsculptured. Preanal scale very broadly triangular, 

 rounded, with one terminal and two smaller lateral lobes. 



Bases of last pair of legs almost in contact mesially. No coxal or 

 sternal armature. Trochanter and femur with large spines. Femora
