Subtribe LAMiiTiE. 

 Genus T^niotes, Serv. 

 Serville, Ann. Soc. Eni. Fr. iv. 

 This well-known and handsome genus is the only one belong- 

 ing to the typical Lamiaires found in the Amazonian forests, 

 the allied genus Ptychodes, common in other parts of Tropical 

 America, being absent from the low-lying Equatorial region. 

 The other Tropical American representants of this subtribe, so 

 rich in forms in the Old World (namely, Plectodera, Hanimo- 

 derus, and Deliathis), seem to be confined to the northern por- 

 tion of the zone — Central America, Mexico, and thence extend- 

 ing into the Southern States of North America.

I met with this fine species only in the neighbourhood of 

 Para, on felled trees in broad roads through the forest. The 

 terminal ventral segment in both sexes is broadly truncated, 

 with a distinct spine at each angle. M. Guerin-Meneville (Icon. 

 Regne Animal, p. 243) believes this species to be the same as 

 the T. subocellatus of Olivier (Ent. no. 67. pp. 69, 89, pi. 2. 

 f. 12 a, b), and that the latter is founded on a worn or immature 

 individual.
