(The animals described by Latzel, Muhr, and Berlese as 

 S. notacantha, Gerv., do not belong to this species.) 



Material. — Many specimens from two localities. 



Head (fig. 3 a). — Moderately long, about one fourth longer 

 than broad. The central rod apparently interrupted a little out- 

 side its middle, and here provided with short lateral branches ; 

 slightly in front of these branches the rod is again Yerj 

 plain, but more narrow, and the frontal branches are scarcely 

 perceptible. 



Antennas. — They contain fifteen to eighteen joints. All 

 seta3 in the central whorls naked and tapering from the base 

 to the end ; on the five or six most proximal joints the seta3 

 on the inner side are somewhat longer than on the outer side, 

 and directed much forwards. A secondary whorl begins 

 below a little before the middle of the antenna, but it is not 

 developed on the upper half of any of the distal joints 

 (fig. 36). 



Scuta. — The second scutum (fig. 3c) with the hind margins 

 between the terminal part of the processes nearly semicircu- 

 lar, and adorned with a transverse band with numerous shai-p 

 longitudinal stripes; the processes are a little longer than 

 broad at the base, with one rather long seta near each 

 margin besides the subapical one; the antero-lateral setae 

 are very long, rather considei-ably longer than the length of
