The antennal leaflets in this species are much more elongated than in P. cornutus and 

 P. zodiacus, but they vary in length in different individuals, the first leaflet being 

 sometimes more than twice the length of the body of the joint. 



VETUKIUS. 



Veturius, Kaup, Monogr. der Passal. p. 110. 



Kaup includes in this genus five species from various parts of Tropical America. 

 All are of large size, and distinguished by the anterior margin of the thorax forming in 

 the middle a rounded lobular projection.

This species varies in length, from 32 to 52 millim. ; in the depth of the elytral striae ; 

 and in the rugosity of the remarkably broad and deep sulci on the lateral margins of 

 the thorax. One small example from Costa Rica has quite faint elytral striae.
