This injury is often quite serious on asmall area, as we have seen 10 per cent of the stalks entirelydenuded of squares in small fields in Texas where this insect wasabundant. The little caterpillars hollow out the squares in thesame manner as does the bollworm, often destroying all of thoseon a plant knee-high and even boring into the tender stalk. The.

They are the larvae of a daintylittle butterfly (Fig. 176), of a bluish-black color, with dark red-dish lustre, and with bright red spots on the posterior borderof the hind wings, common around cotton-fields. The smallyellowish, transparent eggs are laid on the leaves and stems ofcotton, cow-peas, goat-weed, and various weeds, and the larva?have also been found on hops, beans and cow-peas, seeming to * Uranotes melinus Hbn.
