on the Island of Vancouver, ]3. C.? Thelarvae found there by myself were quite con-stant, and correspond exactly with Hy. Ed-ward’s original description. They differstructurally from the larvae of O. antiquawhich were found right across the water atPort Townsend, Wash., and in various placesin New England and northern New York.But O. badia when brought to New Yorkand exposed there, attractedtiqua and hybridized with them. It wouldseem as if O. badia was an isolated local racecut off from communication with the parentspecies by the water surrounding VancouverIsland. If this view is correct, the nameshould stand for the race. I append brief de-scriptions of all the early stages of both O.badia and O. antiqua for comparison.OR6YIA ANTIQ..UA race BADIA Hy.

At the end of the stage a reddish spotappears centrally on joints 9 and o.Second stage. As before, except that the

two retractile tubercles on joints o andhave appeared. They are orange red, as arealso the bases of the large hair bearing wartson joint . There is a whitish lateral lineand the white patches on joints 9 and 3 areorange tinted. Width of head 0.75 ram.

Subdorsally onjoint 2 is a pair, and dorsally on joint x2 asingle short, square, black pencil of plumedhairs. On joints 5-8 are four bush-like tuftsof hair, growing from warts and the upperparts of ii; pale brown or black on joints 5and 6, yellowish and smaller on joints 7 and8.

There is a pair ofplumed black pencils from wart ii on joint 2,from wart v on joint 5 and a single one dor-sally on joint I2; also a pair of simple whitepencils from wart v on joint 5, and in oneexample an additional pair of black plumedpencils from wart v on joint 7, distinct andonly a little shorter than the others.

p. 774.Dr. Packard describes a larva appearing

much like O. antiqua, but says: "It differsfrom O. leucotigma in having a pair of largeprothoracic lateral black pencils" [besidesthe usual subdorsal ones?] and there are"three coral retractile warts." I would liketo call particular attention to this form. Itevidently differs structurally from any of theknown North American Orgyia in havingthree instead of two retractile tubercles,besides apparently having two pairs of hairpencils on joint 2. It must be an undescribedspecies. The larvae were found on pine.The following table will serve to distinguish
