 the 3rd joint longest, the 5th and 6th subequal, the 4th the 

 shortest, all the joints except the first 2, with strong incomplete

3. Veins of the fore wings very narrow and of the same dia- 

 meter, the first 2 obliques widely separated from each other at 

 the bases, the hind- wings with 2 obliques, of which the inner 

 one being not distinct.
