tip, deeply scooped there semicircularly, and the two apical inner 

 spurs are compressed, dilated, especially on the posterior legs, and 

 rounded at tip, anterior tibiae strongly tri-dentate outwardly, anterior 

 tarsi slender and with the claw nearly equal in both sexes. The 

 genital armatures are very similar in the four South African species, 

 and do not help much in the identification. The shape of the 

 vertical frontal part imparts to the species included in this genus 

 a very peculiar aspect. They are occasionally met with dragging 

 themselves wearily along in herbaceous places, but I have also found 

 T. faunus imbedded in the soft, wet sand on the banks of streams, 

 from which it emerges when the bank is tramped upon. 



Key to tlic Species. 

 A-. Elytra impunctate. 



Frontal part retuse at tip or feebly incised ; prothorax of male not 

 deeply excavate in front for half the length, and not tuberculate 

 in the posterior margin retusiis. 



Frontal part crescent-shaped at tip ; prothorax of male with a 

 median excavation extending to half the length, and with a 

 tubercle on the posterior margin ; posterior part with a median 

 smooth broad space c.lype.afns. 



Frontal part crescent-shaped or produced into two long vertical 

 horns ; prothorax of male with a median excavation extending to 

 half the length, and with the posterior margin more or less dis- 

 tinctly tri-tuberculate, posterior part with a very narrow smooth 

 longitudinal space hiibalus. 



A'. Elytra distinctly punctate and striate in the anterior part. 



Frontal part produced into two sub-vertical horns on the male, or
