Cfijyut antice qnadratum, tuberibus antenniferis basi sub- 

 approximatis vel remotis. Oculi profunde emarginati. 

 Antennce in maribus corpore aliquando diiplo longiores, 

 in feminis multo breviores; scapo elongato, cylindrico, 

 apice producto ; articulo tertio multo longiore, rarissime

M. Blanchard i^nbi sup.) proposed the genus Corethrophora for 

 a species (C. semiluctuosa), which I am unable to distinguish 

 satisfactorily from Cacia. Almost the sole character to authorize 

 its separation is the stronger and more approximate antennary 

 tubers; but this character is niodificd in individuals belonging to 

 what I believe to be the same species — a species subject to such
