NOTES ON GLUPHISIA.

BY HARRISON G. DYAR, NEW YORK CITY.

Dr. Packard has recorded his opinion Northwest, and thus more similar toconcerning the species of Gluphisia in the Atlantic district.the August number of tsyche. From Dr. Packard is inclined to consideran examination of the same material, I G. alaofascga and allies as "climatichave reached somewhat different con- varieties" of G. ride,zda. As he doesclusions, and it may not be witlout not define this term, I understand himinterest to compare the two views, to mean that they are modified to theirThe principal difference is in regard to present form by the direct influence ofG. wrigtii. Dr. Packard considers it the climate of their habitat, and that ifto be close to G. severa while I regard removed to some other region, theyit as the of G. alaofascia. I think would not remain constant in theirthat Dr. Packard has allowed himself characters. That this is so cannot beto be led too closely by the statements assumed without proof, though theof Henry Edwards, published with his experiments of Weismann and others,original description. _As in the case of to which Dr. Packard refers, mightZctyura iria, where Dr. Packard seem to indicate it.has simply copied Edwards’s statement I have not been able to perform anyas to the relationship of that species, so experiments in regard to these cases inhere he repeats this course. I have Gluphisia; lut I have done so inshown that Z. aifiria is not at all Ichthyura. There is a pale form ofclosely related to f.

therefore, to regard the climatic formsof Gluphisia as permanent, probablyproduced by the action of nalural selec-tion to fit them to their surroundingsI class them as local races, by which Imean that they are constant in their

Size small; no basal yellow dot ( Gluphisia).With a yellow (or black) central band on primaries,

NOTES.--On September I2th I caught, inBrookline, Mass., a large, battered ailiocresj3ontes, which was flying rather feeblyabout some Salvias. It is the only onehave seen flying in Massachusetts.At Nonquitt, Mass., Miss Ida M. Eliot and

I had two larvae, Arctians unknown to usand certainly not acrea, of a cream-whitecolor. The body was cream-white with threebroken, blackish, longitudinal lines. There

were no dark hairs. These larvae we fed onwild indigo-plant, Batisia tinctoria, andafter a few days the larger larva moulted,coming out of a deep, glossy, indigo-bluecolor, almost black. The smaller larva firstmoulted ofa deep-blue gray color, then againof a deep blue like the other. These larvaegrew to a length of nearly 3 inches, and werevery striking in appearance
