This genus has been as yet confined to the American 

 continent, but the species described below appears to belong 

 to the genus, which is distinguished by the closed fourth 

 posterior cell of wing before it reaches the margin, by the 

 absence of a style to antennae, by the comparatively long 

 first two joints of antennae, and by the wide head. The face 

 has no tubercle and the moustache is almost confined to the 

 oral opening. My new genus Neosaropogon is distinguished 

 from it by the fourth posterior cell of wing being open or 

 only narrower at border.
