the cell ; the second just before the end of the cell ; the third nearer to the apex than to 
the end of the cell. Upper discocellular nervule wanting ; middle discocellular rather 
shorter than the lower. Upper discoidal nervule united for a greater or less distance to the 
median nervule. Internal nervule wanting. 
" Posterior wings mostly broadly obovato, or rounded, sometimes angular. Precostal nervule 
nearly atrophied. Discoidal nervule sometimes appearing to be a third submedian, at 
others thrown off exactly where the subcostal nervure branches, sometimes above that
