In forewings, cross-vein before fork point of Rs 13 wings

In the hindwing of one specimen R4 -f 5 forks 

 near the margin and R^ meets R2 + 3 apically, while 

 R. runs into the margin. Roth R.^ and R5 in this case 

 contain a trachea. In the forewing of another example 

 Ro + 3 is forked apically, and yet another two have 

 R4 + 5 forked apically. In both fore- and hindwings
