The abovementioned species of Veturius may be recognized thus :- 



( The mesosternum hairless and unpunctured except, as a rule, 

 1 in the anterior angle 



I The mesosternum with hair-bearing punctures behind or at the 

 ( side , as well as in front 



(The anterior margin of the pronotum practically straight, only 

 the anterior marginal groove sinuous ; this groove almost 

 complete across the middle line, where the pronotum is some- 

 what strongly convex immediately behind it 

 The pronotum normal, its anterior margin sinuous with widely 



broken marginal groove 

 The frontal ridges and inner tubercles present ; the two lowest 



terminal teeth of both mandibles fused at base only 

 The fronta 1 ridges and inner tubercles absent ; the two lowest 

 terminal teeth of both mandibles completely fused 

 ( The middle tibiae with spines above their ends 

 i The middle tibiae without spines above their ends 

 The two lowest terminal teeth of both mandibles completely 

 fused (spines present above the ends of the middle tibiae ; the 

 elytra hairless at the shoulders) 

 The two lowest terminal teeth fused at base only, in unworn 



specimens, on the right and usually also on the left mandible 

 The two lowest terminal teeth of the left mandible completely 

 fused (no spines above the ends of the middle tibiae ; the 

 elytra hairless at the shoulders) 

 The two lowest terminal teeth distinct at apex in unworn speci- 

 mens on both mandibles. 

 Ç The elytra with a tuft of hair on each shoulder 

 7 j The elytra without any such tufts, (the middle tibiae without 

 V spines above the end) 

 The central tubercle normally situated, at least as far from the 

 inner tubercles as these are from one another ; the elytra 

 normal ; the middle tibiae without spines above the end 

 o) The central tubercle set unusually far forwards, being nearer to 

 the inner tubercles than they are to each other ; the elytra 

 less glossy tha the head and thorax ; the middle tibiae with 

 spines above the end 

 f The central tubercle situated at least as far from the inner 

 tubercles as these are from one another ; the obsolete frontal 

 ridges meeting in an acute angle 

 The central tubercle situated nearer to the inner tubercles than 

 these are to each other ; the frontal ridges meeting in an 

 obtuse angle 

 The central tubercle normal, not free at apex ; the frontal 



ridges moderately distinct 

 The central tubercle slender, with free apex ; the frontal ridges 

 obsolete
