Ornamentation of abdomen as in certain Melccta, the bands all inter- 

 rupted — those on first and second for about same distance, on the 

 fourth and fifth a little wider. The bands on first segment are narrowed 

 to rounded points within, and have no ventral extension, those on fifth 

 occurring as large lateral spots; the lateral enlargements are anteriorly 

 narrowed and rounded, those on second segment not reaching anterior 

 margin, those on the ren.aining segments occupying the entire width 

 of the segments. The venter is entirely black. The legs are colored 

 as in arizonersis except that the femora lack the fringes of dark 

 plumose hairs below. The wings are smoky throughout, slightly paler 

 basally.
