MILLIPED GENUS DIXIORIA — HOFFMAN 13 



Diagnosis: Distal end of telopodite of male gonopod somewhat 

 expanded, with a large curved subterminal tooth (B) and a much 

 smaller and thinner one adjacent to it on the outer side. The pre- 

 femoral process is nearly straight along its outer margin, which is 

 sub terminally notched or indented. 



Ecology: This seems to be an altitudinally restricted form. The 

 altitudes of most places at which it has been taken exceed 3,000 feet. 

 It occurs in hardwood and mixed forests, but not in the spruce-balsam 

 stands which cover the tops of the Iron Mountains. More diurnal 

 in habits than most xystodesmids (perhaps a function of its very 

 moist habitat), coronata is often seen abroad during the day. A 

 mated pau* was found on July 1. 



Distribution: The Iron Mountains in Grayson and Washington 

 Counties, Va., and Johnson County, Tenn. Its northern limits are 

 probably reached just north of Mount Rogers, but just how far it 

 goes into Tennessee along the Iron Mountains remains to be 

 determined. 



Distributional records and the specimens upon which they are 

 based are as follows: 



Virginia. Grayson County: East side of Mount Rogers, 5,000 feet, Kleinpeter 

 and Hofifman, June 30, 1947 (RLH) ; gap between Blufif Mountain and White Top, 

 Fowler and Hoffman, June 19, 1950 (RLH); Chestnut Mountain, west of Volney, 

 Dr. and Mrs. S. T. Brooks, Aug. 13, 1941 (CM); Elk Garden Ridge, between 

 Mount Rogers and White Top, Dr. L. R. Cleveland, July 15, 1947 (RLH); also 

 by Dr. and Mrs. Brooks, July 29, 194] (CM). Washington County: Straight 

 Mountain, east of Damascus, Brooks, July 23, 1941 (CM); Coocoo Mountain, 

 near Damascus, Brooks, Aug. 19, 1941 (CM); base of Laurel Mountain, 4 miles 

 southwest of Konnarock, Leshe Hubricht, May 28, 1951 (RLH). 



Tennessee. Johnson County: Northeast corner, "across line from Taylor's 

 Valley, Va.," Brooks, Aug. 19, 1941 (CM).

Type specimens: Holotype, allotype, and paratype (USNM 2013), 

 topoparatypes (RLH); from Big Walker Mountain, along the west 

 side near the top on U. S. Highway 52, about 10 miles east of Bland, 

 Bland County, Va.; collected by J. A. Fowler and R. L. Hoffman, 

 June 24, 1950. 



Diagnosis: Prefemoral process of male gonopod with a strong, 

 somewhat rounded, subterminal shoulder along the outer margin; 

 telopodite distally expanded with both subterminal processes well 

 developed as in D. p. coronata, process B somewhat larger than in 

 that form. 



Ecology: The following notes were made at the type locality: 

 "... the area at which we collected seemed to be a talus slope of 

 large boulders, but the whole area overgrown with a rich mesic woods
