long as deep; tlie anterior claw is rather robust and mucli 

 curved (fig. 2/), considerably longer than or nearly twice as 

 long as the other. 



Cerci (fig. 2 g). — Rather short, somewhat shorter than the 

 last pair of legs, from a little more than three times to four 

 times longer than deep, and decreasing slightly in depth from 

 the base to near the termiual area; they are set with rather 

 few sette, somewhat unequal in length, and the longest distal 

 ones somewhat shorter than the depth of the cerci. The 

 terminal area is long, only a little shorter than the depth of 

 the cerci, and looks downwards; the surface above the area 

 with about seven coarse transverse lines (consisting as usual 

 of minute spines). The apical seta is as long as or somewhat 

 longer than the depth of the cerci. 



Length. — The largest specimen is extended, and measures 

 1*75 mm., a small but adult specimen 1'2 mm. 



Locality. — Palmi, Calabria, four specimens captured (by 

 the author) together with S. microcolpa, and a fifth speci- 

 men was taken (by Mr. C. Borner) at Catania or at Palmi, 

 besides one specimen from Marburg, Germany (Mr. C. 

 Borner). 



Remarks. — This small species is easily separated from the 

 other species of the group by the very few setse at the 

 margins of the scuta, by the shape of the cerci and their few 

 setas, finally by the legs. 



4. Scolopendrella Silvestrii, n. sp, PI. G, figs. 3 a — 3 g. 



Material. — Three adult specimens, and one specimen with 

 eleven pairs of legs. 



Head. — Elongate, nearly one half longer than broad. 

 The central rod interrupted at the middle, its most anterior 

 part and the anterior branches evanished. 



A ntcnnie. — The number of joints in four complete antennas 

 varies from seventeen to twenty-two. The seta) in the 

 central whorls (lig. 3 a) arc all slender, tapering from the 

 base and naked, moderately short on the proximal and short
