    • n heliothis A genus of noctuid moths, giving name to the family Heliothidæ. The antennæ are pubescent, the thorax and abdomen smooth and not tufted, and the fore wings slightly angulated. The best-known species is H. armigera, which is widely distributed in both the old and the new world. It is usually of a pale clay-color, with the fore wings variegated with pale-olive and dark-rufous, a dark spot in the middle of the wing being especially conspicuous. The larva, known as the boll-worm and cornworm, is very variable in color, but is always marked with longitudinal dark and light lines and covered with black setigerous spots. It is especially injurious to the fruit of cotton, maize, and the tomato. H. marginata is known as the bordered sallow.
