angle. A well-marked tubercle is sometimes present between the frontal tubercles. The 

 scutellum is strongly punctured, except over a more or less well developed posterior median 

 band and in the lateral angles. The whole of the mesothoracic episterna are punctured ; 

 in the matt areas the punctures bear hairs, but not elsewhere. The mesosternum bears a 

 pair of glossy patches in an ^-shaped matt figure as in V. sinuatosulcatus ; these patches 

 bear a number of hair-bearing punctures, which become thicker on the matt surface 

 anterior and lateral to them, but the median matt band is hairless and unpunctured. 

 The metasternum is almost as extensively smooth as in V. unicornis. In all other respects 

 V. simillimus resembles V. spinifer.

One specimen from Cayenne, one from Surinam, and five from the Peruvian Amazon. 

 Length 35-40 mm. 



Veturius cephalotus was first described from Cayenne, and our specimen from that 

 locality bears a label showing that it was identified by Kaup. The species in our collection 

 which most closely resembles Kuwert's V. cephalotus appears to me to be V . sinuatus, and one 

 of these has been determined as V. cephalotus by Kaup, who regarded the two as identical. 

 Kuwert's V. sinuatus is probably the species described above as V. spinifer although this 

 lacks the hairy shoulders of the true sinuatus of Eschscholtz. 



V. cephalotus differs from V. simillimus chiefly in the absence of the spines above the 



ends of the middle and hind tibiae, and in the uniformly punctured and hairy anterior 



intermediate areas of the metasternum. In addition, the two lowest terminal teeth are 



usually distinct at the apex on the right mandible and sometimes also on the left ; the 



marginal grooves of the pronotum are inclined to be narrower in the anterior angles and 



more strongly punctured behind them ; and the median matt band of the mesosternum is 



inclined to be broader, and the hair-bearing punctures to be more definitely concentrated 



into marginal bands.

Seven specimens from Brazil, including one from Rio Grande do Sul, one from Bahia. 

 and two from Blumenau. Length 37-44 mm. 



V. sinuatus is closely allied to V. cephalotus, but the two lowest terminal teeth, though 

 fused at the base, are distinct distally on both mandibles ; the frontal ridges are often 

 obsolete ; the matt posterior angles of the mesothoracic episterna are hairless and 

 unpunctured ; the metasternum resembles that of V. simillimus ; and the elytra have a tuft 



of hair on the shoulders.

 Two specimens from Chiriqui, Panama, 32 mm. long. 



The head differs from that of V. simillimus in having the central tubercle less elevated 

 and set further forward, with the result that the frontal ridges meet in a very obtuse angle.
