OBSERVATIONS UPON SPILOSOMA CONGRUA, WALKER

Extract

On the 29th of June, 1897, I found, in the Gomin Swamp, two Spilosomas, females, lying side by side. One of them was much spotted, and presented the exact appearance of the insect which is figured, with closed wings, in the original edition of Dru Drury's work, and named by him Bombyx cunea. The other was white, but on the median nerve, at the angle of the second fork, there was a small black dot, hardly perceptible. The thorax was clothed with light down; the abdomen was white and spotless. The eyes were black, as were also the under sides of the antennae and feet. The front of the thorax under the head was luteours.

This second moth laid eggs on the 10th of July, and the eggs produced larvae which, in due time, pupated. The moths appeared in the following spring.
