^* Note, Aug. 8.—By August Ist a few larvæ had left the stems and entered the ground; by the 8th, the day of last examination, many had done so. Small ones are comparatively few. Among the smaller ones there was an abundance of that second form described by Prof. Scudder, in Psyche, Vol IV., p. 303. Some of these were isolated, and after a few days they moulted, giving tghe typical form. This seems to prove that there is but one species. It may be interesting to note that these larvæ will feed in the stems and roots of Echinocystis lobata; also in the fruit of the musk melon. I have not watched them to maturity in either.

Note 2, August 26.—On my return to Columbus, August 25, I found that three examples of the imago had emerged in the vivarium from the larvæ placed therein between July 15 and August 1. My son had noted the dates of appearance, as follows:—One each on the 20th, 21st and 23rd; to-day a fourth emerged, and three fresh ones were captured in the field. These facts I consider sufficient to prove that in central Ohio there may be a second brood.
