but is cylindrical at the base, tapering gradually 
to a fine point. Podocephalic canals absent. 
Legs I and II with basifemur and telofemur 
distinctly separated from each other, III with 
femur undivided, so that legs I and II have six 
free segments beyond the coxa while III has only 
five. Vestigial setae absent from patella and 
tibia of all legs; eupathidial formula 2-1-0. 
Tarsus I with solenidion at 0.51-0.59, fi at 
0.67-0.77, e d and companion seta at 0.95-0.98; 
averages 0.55, 0.72, and 0.97 respectively (ten 
tarsi I). Tarsus II with f 2 at 0.32-0.39, s 2 at 
0.40-0.47; averages 0.36 and 0.43 respectively 
(nine tarsi II). Other chaetotactic features of 
legs as shown in table. All tarsi with two claws, 
the posterior more erect than the anterior. 
TYPE LOCALITY : Angeles National Forest, Los 
Angeles County, 2.1 miles (by road) northwest

This is a humus inhabitant, collected in the 
park at Versailles, France, under ”rouseux 
Andre described their color as ". . . rouge pale, 
blanchissant rapidement dans 1’alcool.” C. deli- 
tescens is not colored in the living state, except 
for the yellowish sclerotized areas. 
Andre’s description was based on the adult, 
not on nymphs. The presence of only two pairs 
of genital acetabula in the Johnstonianidae gen- 
erally indicates a nymph, but Charadracarus is 
an exception. Andre described a well-developed 
spiniform seta anterodistally, in addition to the 
odontus and four long setae, making a total of 
six for the segment. The writer has studied the 
type slide, and the "spiniform seta” actually is 
only a little shorter than the other setae of the 
tibia, other than the odontus, and has the same 
form as in C. delitescens and C. hurdi (Figs. 7 
and 44 of this paper).
