short, black, connected with dorsal stripes by a black, transverse stripe, 

 their margin irregular, with projections forming separate dots. Ventral

 with a small reddish brown spot in the middle, with small posterior dots 

 laterally. Seiyae yellowish or light brown, their form and arrangement as

 of the stripes and spots.
