Heretofore no species has been reported from North Amer- 

 ica. 



For the most part members of this genus are white and 

 more or less opaque; the head is narrow and compressed; 

 the antennae have the first joint short, the second large 

 and swollen, more or less pointed or truncate, the third 

 consisting of a fine seta ; the elytra are very long and rather 

 narrow, much larger than the wings, both vitreous, with the 

 veins very light in color with occasional more or less ob- 

 scure markings. One of the best characteristics is the large 

 number of long, narrow, and very regular apical areas.
