Material. — Many specimens from various countries. 



Head. — In all respects as that of S. Isabella-. 



Antenna^. — They contain fifteen to twenty-one joints. 

 As to the central wlioils, they differ scarcely from those of 

 S. Isabellas, but the secondary whorl begins at the middle 

 of the antenna), and only on a few distal joints is it developed 

 on the upper side; on these distal joints three seta; can be 

 seen on the lower margin. The joints present very few clear 

 circular spots on the outer side. 



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

 margin between the processes straight and without trans- 

 vei'se band ; the processes are of moderate size, a little 

 longer than broad, along the inner margin with two setas, 

 one of which is inserted even just in front of the base, and 

 three setfe at the outer margin, while the distal seta is seen 

 near the end. The distance between the processes is some- 

 what longer than their length. The antero-lateral seta3 

 nearly as long as or a little longer than the processes; from 

 the antero-lateral seta to the apical one there are six or seven 

 moderately or rather long sotte. The third scutum (fig. 1 a) 

 has the processes a little shorter than broad, with two or 

 ;three setae along each margin, the distance between the 

 processes at least twice as long as their length ; the antero- 

 lateral seta3 as on the second scutum. 



Legs. — The last pair (fig. 6 <i) a little shorter than in 

 S. Isabellas. The tibia and metatarsus each Avitli two 

 protruding dorsal setas, and the longest seta at most nearly 

 as long as the depth of the metatarsus. The tarsus not quite 

 four times longer than deep, with thi'ee protruding seta3 in 

 the anterior dorsal row, and these setas are about as lone- as
