which is recorded from Ohio, Pennsylvania, Kentucky, Virginia, 
and District of Columbia. It is the only species recorded from Ohio; 
our Franklin County specimens constitute a new northern-most 
record in the state, and are one of the very few American records of 
the genus in glaciated territory. The Alabama japygid keys (in Paclt, 
1957, and Smith and Bolton, 1964) directly to Metajapyx steevesi 
Smith and Bolton, 1964, known from Mississippi, Alabama, Geor- 
gia, South Carolina, North Carolina, Tennessee, and Virginia. Our 
record is especially noteworthy because it marks the southernmost 
limits of both the species and the genus in North America.

CLEANING. Involves grooming with the mouthparts. 
Antenna Clean. Passage of the antenna through the mouth is 
accomplished in two major modes: unassisted and assisted. In 
unassisted, which is the usual mode in Diplura, the antenna deflects 
into the mouth due to its intrinsic musculature, and the legs are not 
involved. In Campodea this movement is vertical to the substrate, 
the antenna is curled ventrally under the head and is chewed by the 
mouthparts; in japygids the movement is rarely vertical, the antenna 
usually is curled along a more horizontal plane from an initial 
position lateral of the head, and is usually drawn rapidly through 
the open mouthparts; less frequently it is chewed by the maxillae. In 
the much rarer assisted mode, the ipsilateral foreleg pulls the 
antenna into the mouth and in both families is either returned to the 
substrate or held in mid-air; in addition, the japygids were occasion- 
ally observed using the ipsilateral foreleg to help hold the antenna in 
the mouth by placing the leg crosswise in front of the mouthparts. 
Pages (1967) points out that in Dipljapyx the foreleg holds the 
antenna during chewing by the maxillae, but is not used when the 
antenna is drawn through the maxillae without chewing movements. 
Palp Clean. A maxillary palp is passed unassisted through the 
mouthparts in the anterior mode in which the palp tip projects 
posteriad and is drawn anteriad out of the mouth. This was 
observed clearly in Metajapyx. (In Campodea, maxillary palpi are 
one segmented and the labial palpi are vestigial.) 
Foreleg Clean. A foreleg is raised and extended forward while 
the head turns to the side to reach it; the leg is essentially in a ventro- 
lateral position during cleaning, and is drawn posteriorly through
