By Henry L. Viereck, \<ir Hitrrii, Conn. While at the Connecticut Agricultural Experiment Station the writer made some observations on this sjjecies which seem to be new. Larva^ of Anthremis cerhasci had been kept in a tube with cotton fibers during the winter. After subsisting on the cotton the speci- mens were transferred, in the spring, to Syracuse ^vatch glasses, lined with black woolen cloth, where the}^ could be readily w^atched and fed Avith dried insects. One day a female specimen was observed with an *?gg partly pro- truding from its ovipositor. When first seen it had the ovipositor, with the egg. inserted in the woolen cloth; then it seemed disturbed, for it walked around with the egg nearly all the way out, but made no apparent effort to drop it. A short time after this observation the egg had been dropped. The laj'ing of this egg could not have taken more than five minutes. Eggs were first noticed about March 1. On March 15 four eggs were put on a piece of cloth, which was pinned into a Schmitt box with no insecticide in it; another lot of four eggs was put on a piece of cloth and pinned into a box containing three iia})hthalin cones. April 7 the eggs in the box without naphthalin had hatched and the larva^ were lively. In the box with the naphthalin two eggs had matured embryos or young larva?; one larva had eaten the end ofl' the egg preparatory to emerging, but there died; the other did not suc- ceed in cutting through the cover, though it was apparently as far advanced in development as the first specimen. The second embryo had evidently inhaled the fumes of the naph- thalin through the thin membrane or the micropyle. This experiment seems to demonstrate that naphthalin does not retard the growth of the embryo in the egg, but does prevent the young larva fro
