tapering and ringed in the distal half; tlie lateral pair is a little 
shorter than the submedian dorsal pair; a third pair conld not be 
seen with certainty. — The anal plate is sliaped as a transverse 
oval with a comb of six branches projecting from the hind margin; 
the four inner branches are subequal, very siender and longer than 
the plate, the lateral pair is thicker at the base, acute as the other 
pairs but only half as long. 
Legs. They are rather short and increase only little in length 
posteriorly. The last pair (lig. 4 d) is moderately robust; the 
femur is as long as the trochanter, somewhat longer than thick and 
somewhat shorter than the tibia, wliich is twice as long as thick; 
the tarsus is a little more than one half longer than the tibia. 
The hairs on coxa and trochanter are biramous, with clavate, rather 
robust, ringed branches; the seta on the tibia is half as long as 
the joint. 
Length. The specimen measures *77 mm. 
Locality. Captured (by the author) in a wood of oli ve trees 
at Palmi (Calabria, Southern Italy), May 17. 1893. 
Remarks. The species is easily distinguished from all other 
forms known to me by its anal plate. But also the combination of 
the other characters described may be sufficient for its recognition.

Material. Two immature and well-preserved (male) specimens, 
each with eight pairs of legs, are the types for the description. 
(A third younger specimen with six pairs of legs has been left 
out of consideration, but its anal segment is represented in fig. 5e). 
Head (fig. 5 a). The eyes are of middle size, nearly three 
times longer than broad, and the distance between them is a little 
shorter than their length. — The hairs are rather clavate with 
exception of the outer pair in the second and the fourth row; all 
are ringed. The hairs in the first and third rows are moderately 
short, in the second row the inner pair is a little longer and its outer
