Additionally, the acropodite occasionally does not loop over the prefemoral 

 process, but lies roughly parallel to it (Fig. 38). 



Ecology — According to labels with preserved samples, M. elrodi 

 has been encountered in a field under stones and logs, under rocks, 

 and in moss near a small woodland stream. The specimens that I 

 collected in Boundary and Bonner counties, Idaho, were found in 

 moist deciduous litter in hardwood patches in predominantly coniferous 

 forests; those from Idaho County were taken from litter in a ditch 

 beside a walkway in a large area of deciduous trees; and that from 

 Pend Oreille County, Washington, was encountered under a log and 

 rock on a talus slope in a cool, moist cove along a stream. Loomis 

 and Schmitt (1971) encountered the milliped between and under rocks, 

 moss, logs, cedar bark, in rotten wood, between rocks just above the 

 splash zone of cascading water in a stream, at the base of a talus 

 slide, and in a red cedar, Douglas-fir forest. Sites were typically in 

 creek bottoms with thick humus layers, and a number of specimens 

 were taken in cedar groves. 



Distribution — Spokane and Stevens counties, Washington, to Lake 

 County, Montana, and from just south of the International Border in 

 Boundary County, Idaho, and Pend Oreille County, Washington, to 

 northern Idaho County, Idaho, north of the transverse stretch of the 

 Salmon River. The area is approximately 242 mi (387 km) in the 

 east-west dimension and 216 mi (346 km) in the north-south. The 

 Whitman County, Washington, record is from the Columbia Plateau, 

 and most of the other sites are in the Northern Rocky Mountains 

 Physiographic Province. Specimens were examined as follows:
