colour, and also in the structure of the posterior pair of legs, and in the greater 

 length of the antennae, which have twenty articulations. 



The posterior legs are convex on the upper surface with the margins rounded, 

 and the spinulse arranged almost as in S. cingulata.

This species resembles S. cingulata, but is quite distinct from it. The head is smaller, an- 

 tenna shorter, and posterior legs more convex. The cephalic segment is small, convex, 

 subcordate; labium smooth, flattened, narrowed; dental plates subquadrate, very di- 

 stinct, with the margin rounded ; teeth distinct, ten, black ; posterior pair of legs with 

 the femoral and tibial joints equal, smooth, and somewhat flattened on the upper sur- 

 face, with the external margin rounded ; internal margin with five spinulre, the four 

 posterior ones arranged in two oblique series, two in each series, the apical one elon- 

 gated, with the apex trifid. Inferior surface convex, with three spinulse arranged in 

 a single series. 



There are two examples of this species in the Museum collection, in one 

 of which the posterior legs appear to have been reproduced, as the spinulse 

 are irregular, smaller, and more numerous ; this is a condition which repro- 

 duced limbs frequently exhibit.

Head flattened, cordate, ovate ; basilar segment large ; labium convex, smooth ; dental plates 

 short, transverse, slightly convex, and punctured; teeth eight, short, obtuse, the inter- 

 nal one on each side bifid, mandibular tooth moderate. Lateral anal appendages (coxae 

 of the posterior pair of legs) short, ferruginous, punctured, with the apex trifid, and 

 directed inwards. Preanal scale elongated, triangular, with the margin slightly round- 

 ed, and impressed with a longitudinal sulcus ; superior surface of the femoral, or basi-
