REVISION OF BORARIA AND GYALOSTETHUS — HOFFMAN 323 



So far the egg chambers have not been discovered. On one occasion 

 I found the moulting chambers of B. stricta and made the following 

 notes: 



Sept. 4, 1961. Asheville, N.C. Collected on Beaucatcher Mountain 

 for several hours; conditions very dry; . . . located a small trickle down 

 through the dry woods, here found B. stricta under rocks in wet places. 

 Several adult females, and immatures in two different stages, either in or 

 constructing "igloos." These are oblate spheroid, with a "chimney" and 

 attached at the base, usually found in animal burrows in the wet black mud 

 under flat rocks. . . . The large ones (made by the penultimate instars?) are 

 about the diameter of my thumbnail = ca. 15 mm. 



The typical appearance is about as showTi in the accompanying 

 figure. The chambers being constructed were in the early stages, 

 less than half completed, the milliped working from the inside and 

 apparently using both mouthparts and paraprocts alternately. The 

 occupant must come and go until the last stages, and then complete 

 the roof and chimney with the paraprocts, as the chimney could 

 scarcely be formed by the mouthparts from the inside.

 instar, sketched from life, actual diameter about IS mm. 



Distribution. — The known range of this species coincides closely 

 with the Southern Section of the Blue Ridge Physiographic Province 

 as defined by Fenneman (1938) and as shown by the dotted line in 

 figure 7. Within this area, B. stricta is abundant and easily col- 

 lected in moist or wet habitats. The altitudinal range extends 

 from around 1000 feet in western South Carolina up to 5200 feet 

 or more in the Iron, Black, and Great Smoky Mountains. Probably 

 the existing records depict the actual distribution closely although 

 I would anticipate some slight range extensions at both the northern 

 and southern extremities. 



Specimens (personally collected, and in my collection unless other- 

 wise indicated), have been examined from the following localities: 



Virginia: Franklin Co.: headwaters of Shooting Creek, ca. 4 

 miles SW. of Endicott, IcT, 19, May 28, 1957. Grayson Co.:
