The moths, fig. 3, do not fly readily, but start up before one as he 

 walks along, and then settle at once upon the vines. This habit pre- 

 vents their spreading rapidly of their own accord. On the occasion 

 of my fia-st visit to the bogs at Yarmouth Farms, in June, 1890, the 

 second brood of moths was out, and as we walked over the bog, they 

 would start up by hundreds and settle immediately upon the vines.

They lay their eggs on the under side of the leaves, as shown in 

 fig. 4, which is much enlarged, the line at the right indicating the true 

 length of the leaf. Three eggs are shown in the figure, which are 

 enlarged the same as ihe leaf.

Vine worms were received here at the Station, from Yarmouth 

 Farms, June 2, 1890, which were fed on cranberry leaves and passed 

 their transformations, the moths emerging June 10th. These moths 

 paired and the females laid their eggs June 12th. The eggs are 

 elliptical in outline, very much flattened, about one-thirtieth of an 

 inch long, nearly the color of the yolk of a hen's egg, in the middle, 

 but transparent around the edge. Under a microscope the surface is 

 granulated, and has a few raised lines which form hexagons over the 

 surface.
