[June-September 
of endognathous mouthparts on grooming. The invaginated, non- 
condylar mandibles and maxillae of Diplura might reduce their 
effectiveness in oral cleaning, and result in an increased importance 
of leg rubbing movements. In fact, leg rubbing was seldom observed. 
The rarity of rubbing has two possible explanations: either en- 
dognathy does not significantly modify grooming or else most leg 
rubbing movements have not yet evolved in Diplura. 
Material Examined 
Campodeidae (seven specimens and seven hours of recorded 
observations plus about five additional hours of non recorded 
observation which add no new data) Ohio, Franklin Co., Columbus, 
Upper Arlington, 20 September, 1975, B. D. Valentine family, in 
soil in back yard (1 specimen). Same data except 5 November, 1977, 
in soil under boards and logs in back yard (6 specimens). Many 
additional specimens were seen and collected by breaking up clods 
of dirt in a garden. 
Japygidae (three specimens and nine hours of recorded observa- 
tion plus about four more hours which duplicate previous data). 
Alabama, Butler Co., 2 mi. N.W. McKenzie on U.S. rte. 31, 7 
December, 1975, B. D. Valentine, R. L. Stoffer, A. J. Penniman, in 
rich humus under leaf litter (1 specimen). Ohio, Franklin Co., 
Columbus, 23 October, 1977, M. J. Glorioso, under large flat rock 
at base of overgrown hill (1 specimen). Same data except 24 
October, 1977 (1 specimen). 
The campodeids key to the genus Campodea subgenus Campodea 
Westwood, 1842, in Paclt (1957). Silvestri (1933a) and Pack (1957) 
list two species of this subgenus occurring east of the Mississippi 
River, Campodea (C.) fragilis Meinert, 1865, and Campodea (C.) 
plusiochaeta Silvestri, 1912. Both are illustrated and described by 
Silvestri (1912). Our specimens more closely match C. plusiochaeta 
because the cereal setae are fairly long on all segments, as opposed 
to the long basal and shorter distal cereal setae of C. fragilis, and 
because there are bifurcate antennal setae, as opposed to the serrate 
or plumose setae of C. fragilis. Nevertheless, the determination is 
not firm and the specimens should be listed as Campodea ( Campo- 
dea ) ? plusiochaeta Silvestri, 1912. The Ohio japygids key in Pack 
(1957) to the genus Metajapyx Silvestri, 1933. Using Smith and 
Bolton (1964) they key to Metajapyx subterraneus (Packard, 1874)
