Comstockplaces the Zygieuida high up, remote fiom the Tineina, but at present I amdisposed to regard the Syiitonxida as a distinct group, with a different origin,and more nearly related to the Arctiidte. I fully agree with Chapman that Zyga^na is near the Tineina; and I also agree with Comstock that Tripocris and Pyromorpha have a remarkably generalized condition of wing
