17. Carabodes tridactylus nov. spec. 
(PI. Ill, fig. 5, text-figs. 54, 55.) 
Although the present species is tridactyle I refer it to the genus Carabodes as 
it undoubtly seems to be most closely related to C. labyrinthicus Mich. [6, PI. 21, 
fig. 1]. 
Length 0,63 mm. Breadth o, 49 mm. 
Texture , rough. Colour , deep red-brown. The dorsal side of both céphalothorax 
and abdomen irregularly punctured and densely covered with small, hyalin, more or 
less perpendicular, raised dots. 
Céphalothorax long, narrower than the abdomen and nearly in the same level, 
anteriorly bluntly pointed. Lamellae rather thick, and narrow, almost horizontal 
plates with the same texture as the dorsal side; they run throughout their whole 
length in a slight curve towards each other, extend forwards almost to the tip of 
the céphalothorax, terminating in short cusps at the top of which the small, curved 
lamellar hairs are inserted. 
Interlamellar hairs hairy, straight and blunt, 
situated as far from the middle as from the pseu- 
dostigmatic organs. Pseudostigmata large, lateral, 
much raised, pointing outward. Pseudostigmatic 
organs with slender peduncles curved outwards and 
backwards, and pyriform bare heads (Text-fig. 55). 
First tectopedia very large, shaped like the 
lamellae, plainly seen from dorsal aspect. 
Legs. Coxae III rough with the same texture 
as the dorsal side, flattened. Femora I and II with 
slender peduncles; femora III and IV flattened with 
high, longitudinal, ventral blades; genua I rather 
long with slender basis; genua II — IV short; tarsi 
and tibiae I — IV (especially tibiae IV) rather long with 
slender peduncles. All tibiae and genua I with long 
tactile hairs. Claws tridactyle, slightly heterodactyle. 
Abdomen a little longer than it is broad; posterior margin rounded, antero-lateral 
angles with a short, squared, flat projection; 4 rows of straight, blunt, hairy bristles 
on dorsum of abdomen; 3 pairs of small hairs round the hind margin. 
Ventral side (Text-fig. 54). Texture the same as that of the dorsal side but 
not so raised. Genital and anal apertures large, occupying nearly the whole median 
part of the belly leaving between them a space only as long as */ 3 of the length of 
55 -
