what longer than the distance from the tegulse to the apex of

little wider than the base, its spiracles projecting as tubercles 
at the basal third; second and third segments equal, together 
one-third longer than the first and very narrow; radial cell in 
hind wings divided by constriction, the apical part narrow, the
