other spine, starting from the posterior edge of the segment and back of the line 
of the dorsals, and these also are porrected ; the remaining spines of the six rows 
radiate as if from a central axis, those of the stigmatal row being depressed so 
that their ends are on a level with the feet; the base of each spine deep orange 
or fulvous ; between each pair of dorsals two whitish dots placed transversely ; 
legs and pro-legs black; head small, but broader than the second segment, sub¬
