In the beginning of September, 1898, I discovered, in the heads of burdock (Lappa major, Gætn.), a curious larva, of which the following is a description:

Head bilobed, brown. Mouth organs large. A brown plate, marked longitudinally with a white line, on the second segment. Body rounded, much crinkled, of a fatty appearance, having a few white hairs along the sides. Anal segment small and protruding. The legs small and weak. The pro-legs seemingly atrophied into mere pseudopodia. Length of larva, two and a half lines.
