The length of the antero-lateral seta? separates it also from 

 all other European species of this genus.

Material. — Six specimens from one locality, all with the 

 full number of legs. 



Head (fig. 4 a). — Moderately long, about one fourth 

 longer than broad. The central rod with a sharp transverse 

 suture at the middle, without vestige of lateral branches, but 

 the frontal branches are strongly developed. 



AntennfB. — They were complete in two specimens, and 

 contained respectively twenty-three to twenty-five, and twenty- 

 six to twenty-seven joints. The setas in the central whorls 

 (fig. 4 h) are thick and subcylindrical nearly to the acuminate 

 and somewhat produced end, besides they are very con- 

 spicuously pubescent ; on the inner side of the eight or ten 

 proximal joints two or three naked and slender seta3 are 

 inserted in each central whorl instead of the thick setae. 

 The thick setas on the proximal joints twice as long as those 

 on the most distal joints (fig. 4 c). The joints in the distal 

 half of the antenniD with one seta to three seta) on the lower 

 side as a rudiment of a secondary whorl ; these seta} are 

 similar in shape, but not half as long as those in the central 

 whorl; the terminal joint has its distal half set with a 

 number of pubescent and thick seta\ 



Scuta. — The second scutum (fig. 1 a) with the hind 

 margin nearly straight between the inner base of its pro- 

 cesses, and without any striped band; the processes scarcely 

 as long as ])road, with three to four moderately short sette 

 along each margin, and the distal seta inserted a little fi-om
