That it l)eloni^s here is aiisoliilely certain from tlie hreedin;^' of .Mi'. Kdwards, wli(» lias solvi'd so many otlier points in tiie history of our l)iittcrHies. But now tliat it is known to l)e a form of this H|)ecies, its direct seasonal rehilioii to the otlier forms needs careful invcsti^ration iiotli in the north and especially in those southern regions where the two yellow forms, eripliyle and ariadiic, come into close conjunction or overlap. 'Phis of course can lie mnlertaken only hy those on the spot or at least tliroiijfli their aid, and it is recomineiided that eolloctors in such districts should forward to Mr. Kdwards eij;j;s and young larvae of known parentage with ahiiiidance of the food plant. The olmervations also upon the other forms need to be multiplied in many localities, not the least upon the I'acitic coast, in order to clear up the complete history of the species, and to no one hetter than to Mr. Edwards can he entrusted the working out of these prohlems in their relation to each other. Careful comparison should also lie made lictwecn the seasons of this species and those of its allies wherever it is associateil with others, as it is indeed with one species or another in iK^arly every [tart of its range. .Such comparisons are desiralile in part to ans
