Mentum rounded and deeply constricted near the median part or 

 slightly above it, paraglossae very well developed in the inner face, 

 hairy at the tip but not projecting beyond the mentum which is 

 broadly but not deeply emarginate in the apical part, and the outer 

 sides of which slope diagonally, the ligular part is strongly denned 

 by a transverse suture, and is about one-third of the width of the 

 basal part of the mentum ; labial palpi lateral, apical joint slightly 

 curved, somewhat swollen outwardly, sub-truncate at the apex ; 

 mandibles strong, deeply concave inwardly and having at apex a 

 long sub-horizontal lamellate tooth truncate at the tip ; maxillae 

 robust, armed at the tip with five sharp teeth set in a row and 

 having two teeth set transversely under the upper row ; last joint 

 of maxillary palpi fusiform, very swollen in the outer part, sharply 

 acuminate and deeply grooved along the whole length of the upper 

 side ; clypeus reflexed, more or less parabolic from a certain distance 

 from the base, more or less deeply notched at the apex, or simple, 

 separated from the head by a slightly arcuate suture, vertical in the 

 anterior part and with the anterior margin moderately reflexed, 

 labrum broad, nearly bi-lobate ; frontal part simple, hairy, divided 

 from the clypeus by a suture ; eyes very large, divided in the anterior 

 part by the canthus of the genae which are otherwise obliterated ; 

 antennae 11-jointed, third joint very long, only a little shorter than 

 the basal one, second moniliform, fourth very minute, club foliated, 

 7-jointed in both sexes, the two inner joints slightly shorter than 

 the others, the first, however, is sometimes conspicuously shorter 

 <(S. bechuana) ; prothorax ampliated and rounded laterally in the 

 middle, convex ; scutellum neither broad nor long, ogival ; elytra 

 slightly broader at the base than the prothorax at its highest 

 part, slightly ampliated laterally at a short distance from the 

 humeral part, and covering only the base of the propygidium, 

 they are not costulate, and the epipleural fold is very much reduced 

 in the basal part ; pygidium declivous, as long as broad at its widest 

 part, shield-like, somewhat convex in the median part ; abdomen 

 very voluminous ; hind coxae nearly transverse ; metasternum not 

 very broad, mesosternum simple ; anterior tibiae strongly tri-dentate, 

 intermediate and posterior ones with two carinae en chevron, posterior 

 tibiae broadly dilated at the tip, and provided with two inner flat 

 spurs rounded at the tip and conspicuously dilated in the female of
