Head slightly impressed on each side, the forehead with a mesial, smooth, 

 slightly raised line ; there is alco a very short smooth ridge at the base of each an- 

 tenna. The thorax is not much narrower than the head and eyes, a little narrowed 

 in front and behind, the punctuation very distinct, rather strong and close. The 

 elytra are very broad, convex, not quite so long as broad, with two slight impressions 

 on each, the punctuation very distinct and strong, and moderately close, their sutural 

 margins strongly incrassated. The abdomen is much narrower than the elytra, finely 

 and rather closely punctured, the 2nd, 3rd, and 4th segments constricted near the 

 base, transversely impressed above (as if they had been tied round with a string) ; 

 penultimate segment deeply triangularly notched below.

Allied to ^S*. cicindeloidcs, but very distinct. Very sluDiiig, black, 

 smooth ; bead, thorax, and abdomen much narrower ; thorax longer 

 and much less strongly punctured, broadest in the middle. Elytra 

 more quadrate, broader, more convex, the punctuation similar. An- 

 tenna? with the apical joint distinctly larger than the preceding.

Niger, nitidus ; capite crebre subtiliter punctato, liaud excavate, medio 

 parum elevato, utrinque ad antennarum basin tuberculo instructo ; thorace

Closely allied to the preceding. The punctuation throughout is much less 

 strong, although very distinct. There is a small tubercle at the base of each an- 

 temia (not a short carina) ; the surface of the thorax is even, its broadest part is a little 

 before the middle ; the elytra are longer and a little less broad, with the punctuation 

 less strong, and moderately close ; the abdomen is relatively broader, nearly smooth, 

 the 2nd, 3rd, and 4th segments less strongly constricted, finely and not very thickly 

 punctured at their base; penultimate segment below with wilh a deep narrow 

 incision.
