In its general appearance this species is very like S. cingulata, to which it approaches very 

 closely in the form of the head, the frontal portion of which is cordate ovate, with two 

 longitudinal elevated ridges; antennae slightly pubescent, l7-jointed, green; basilar 

 segment large and wide, with the mandibles strong and projecting, orange- coloured; 

 basilar tooth large, with a tubercle near its apex ; labium orange, smooth, convex, with 

 the sutures very distinct, with a small black spot at the external base of the mandibles ; 

 dental plates quadrate, deeply punctured, with the posterior external angle produced ; 

 teeth six, black, short, and obtuse ; posterior pair of legs slightly elongated ; superior 

 surface of the basilar joint convex, margins rounded, with six sharp spines, arranged 

 in two longitudinal series ; two in a series on the upper surface, and four in an irregu- 

 lar series on the internal margin ; the internal angular spine large, bifid ; interior and 

 inferior surfaces rounded, with six spines on the inferior arranged in two longitudinal 

 series, two in the internal and four in the external.

It is doubtful whether these species may not belong to the subfamily Cor- 

 mocephalince, as I have not had an opportunity of examining them. They 

 are inserted here only provisionally.
