second segment dark chestnut-brown, with a rather broad band at tip. 

 slightly narrowed in the middle anteriorly; remaining segments black, 

 sericeous, with their apical margins yellow ; beneath, the first almost 

 entirely, and the narrow apical margins of the remaining segments, 

 yellow. Length 4 lines; expanse of wings 9| lines.
