both sexes a strong S/, with numerous long sensorial appendages. 
These are in C. capensis and C. caudata filiform tubes, 
as in C. mediterranea, but in C. nobilis they are flat and leaf-like, 
about five on each side of the stem. The 6th joint is in C. nobilis 
longer than the 5th, of equal length in C. capensis, and bears 
distally a very small Se. The 7th and 8th joints are short and 
not distinctly separate. The terminal (7-8) joints carry one 
small Sa, one Sf, one Sz, two strong and long S# and two long 
sensorial filaments. The Sz and Sf carry in the male, at their 
bases, a peculiar sensorial apparatus (Pl. VII., fig. 5), a stylet 
with a cup or funnel-shaped organ. They give off, besides, 
long branches closely following the trunk of the seta. Some 
of these branches carry, in the male, small suctorial (?) 
appendages (fig. 6). The two S# are strong and give also off 
branches. The proximal branches of the antennula of C. nobilis 
are cylindrical, sensorial appendages. 
The posterior antenne of all species resemble those of C, 
mediterranea, as far as concerns the B and the Re (Miiller, fig. 
22). The Rt of C. caudata and C. nobilis (Pl. VIL., fig. 8) agree 
with the Ri of C. mediterranea (Miiller, fig. 21), but in C. capensis 
(Pl. VII., fig. 7) this part is prolonged and 3-jointed, the joint 
between Ri 2 and 3 sometimes being indistinct. 
The mandibles of all species agree completely with the same 
organ in C. mediterranea (Miiller, fig. 14). The terminal joint 
carries in C, nobilis (Pl. VIIL., fig. 10) one Se, three strong claws 
and two Sz, one as long as the claws, one half as long. In C. 
capensis (Pl. VIII., fig. 9) I found only two claws, but two Se, 
and besides the two Sz still a very faint one. 
The maxilla of the three species resemble in general the same 
organ in C. mediterranea (Miiller, figs. 23, 24). 6 1 carries one 
hairy Se. I failed to discover a Se in B 2. On the limit be- 
tween B 2 and the stout Ri there is a chitinous bar, that carries 
the ‘‘lamelliform appendage,” probably representing Re. 
This lamelliform appendage has the same form in all the 
three species and in C. mediterranea. The three lamelliform 
basal lobes carry strong flat and hairy sete, the first lobe ro, the 
two following 5 each. The exterior margin of the Az carries in 
C. nobilis small short hairs, and in the distal part of the interior 
margin some hyaline denticulations. The sete are crowded in 
the distal part (Pl. VIII., fig. 11). There is proximally a group 
of three sete, which probably represent Sz of Ri 1, and on the 
opposite margin 2Se. The intermediate part carries four 
different sets of sete. The three exterior are different in 
different species (see figs. 12, 13). In C. capensis the exterior 
is remarkable for its coarse pinnulation. The 3 Sé are also
