Last June I was in Boston, from the 14th to the 30th, and during this time Alypia octomaculata was in season and very abundant. Had I chosen to carry a net in the public gardens and uptown streets, I suppose I could have taken a couple of hundred specimens, always provided that I wasn't “run in” as a lunatic. As it was, I contented myself with carrying a supply of pill boxes, and succeeded in taking about thirty-five specimens. During two days I was visiting a friend about seven miles from the city, but did not see a single specimen of this species; but in those streets in which there were small plots of grass in front of the houses, they were very common. The spot where I took the most of those I captured was a plot of grass about ten feet by seven, in which there was a Syringa between two Deutzias, both species of shrubs being in blossom.
