FIGS. 27-30. Charadracarus hurdi, n. sp., adult: 27, dorsal solenidia of tibia IV; 28, outline drawings of 
legs I-IV, female; 29, major body setae, female; 30, minor body setae, female. 
C. delitescens and C. grandjeani has no counter- 
part in the other two species (cf. Figs. 29 and 
45). The terminal portion of the major setae 
of C. delitescens and C. grandjeani is cavitated. 
The number and arrangement of the dorsal 
hysterosomal setae also show some differences, 
although these are not as easy to utilize in dif- 
ferentiating between species as are some of the 
other characters (compare Figs. 6 and 31). 
Eupathidia of Palpal Tarsus. In the adult of 
C. hurdi , the most distal of the two distidorsal 
setae has a hollow shaft and is typically eupathi- 
diform in structure. Its more basal counterpart 
is solid, except for a very slight and almost un- 
noticeable basal excavation. In adults of C. deli- 
tescens, both of these setae are solid. In the larva 
of C. delitescens (Fig. 72) the terminal eupathid 
is canaliculate in the basal portion, but this con- 
dition does not persist in the adult, at least in 
the specimens examined by the writer. The sit- 
uation in C. aelleni is unknown, but in the type 
of C. grandjeani, the distal one is hollow, as in 
the case of C. hurdi. 
Paradont of Palpal Tibia. In his original de- 
scription of C. aelleni, Cooreman showed a dis- 
tinct and well-formed paradont at the base of 
the terminal odontus of the palpal tibia. None 
of the other three species of the genus has such 
a seta in this position. It would appear that the 
paradont is not an additional seta in the case of 
C. aelleni, for the setae of the tibia of that 
species are the same in number as in the other 
three species of the genus. The only difference 
appears to be that one of the normal setae in
