I am indebted toM.le Comte Dejean for permission to describe 
and figure this species from his cabinet. It is with considerable 
doubt that I place it in the genus Platyrhopalus, (although the 
structure of the thorax and the flatness of the antenne approach 
the typical species of that genus,) the cornuted head appearing 
to give it an affinity with the Paussi, such as P.spAerocerus, §c.: 
E but from a note made in Paris, I have a slight idea that the 
: labial palpi have the joints of equal length.
