On the evening of Saturday, May 22nd, 1886, being the first warm evening after the electric light system was started in London, hundreds of “electric light bugs” (Camptobrochis grandis) and large green Calosomas (Calasoma scrutator) came into the city, and form that time on throughout the summer, and even as late as Nov. 2nd, the lights continued to attract hundreds of insects every warm evening.

I have sufficiently shown in various places (and the enquiring student may consult the originals) that Kirby's description of Ruficaudis contradicts that of Uniformis, in what we must regard as essential partiuclars in this genus. We have not here to do with a species; but, according to Mr. Hulst's statements, with a dimorphic form of Thysbe, in which the inner margin of the terminal band of primaries is even, not dentate, on the interspaces.

In support of the record relating to the periods of transformation of this beetle, and the probable cause of their pruning the branches of the Oak, which I had the pleasure to contribute to the XVII Vol. of this journal, I now add some further facts, resulting from a recent visit to Clermont, N. Y.
