of Coenocaife m~~mliata; but I do not see any specific difference between these two forms.
Dr. Hulsl placed them in separate genera, but he differentiates these genera only in that HYDRIOMENE has the thorax tufted posteriorly while COE- NOCALPE is not so. Now several C. mafnoliafo from Maine, New York, and New Jersey before me have fully as large thoracic tufts as Hulsl's type of H.pernotata. and some of these specimens have been labeled C. niagiinhaSa for me by Dr. EIulst. Therefore I would transfer C. magnoliafa to HYDRIOMENE and place H. pernotata Hulst as a synonym of it. Henry Edwards is credited with a description of the larva in Proc. Cal. acad. xi.; feeding on FUCHSIA GERANIUM, etc. Egg.

19031 DYAR --NORTH AMERICAN GEOMETRZDAE I95 Eggs were obtained as early as July 5th when the moths had only just begun to fly, but all the larvae hibernated.
Many were very small, only a few reached the fifth stage in the autumn.
They were fed on POLYGONUAI, but arc probably rather general feeders on low vegetation at the ground. The coloration is adapted
both for concealment in such a situation and for hibernation at any stage after the first.

DciZi~z'ia erythremaria Guen&e.
My adults agree with Vancouver Island speci- mens, called Dezlinia pacificaria Packard. I do not think that the form' is specific- ally distinct from the Atlantic coast D. eryt/;re~7za~i(t Guen. The slightly larger
size and very slightly more distinct markings do not seem to justify more than a racial distinction. In Bulletin 52, U. S. nat. mu., Dr. Hulst credited the European D. exam//Ie~mzta Scop. to "Canada." If this is correct, I would refer both D. facificaria and D. er~L?hTwlza?-ia as varieties of the European species, though I think it is more probable that the European form does not occur in America ;it all. The European larva is clescribecl as entirely green or with pale dorsal lines. EQ'Q'.
