The insects falling in this subfamily have the same habits as the Alysiinc e and exhibit scarcely any structural difference; the only character yet pointed out to separate them from the preceding being the difference of venation in the front wings.

In all genuine Dacnusines the first transverse cvbiUis is always present. He must also bear in mind that there are no apterous females in this group.
