Mr. Wm. Saunders has collected a species of Crambus, which is apparently unnoticed by Prof. Zeller or Dr. Clemens, who have written most frequently on our American species. The new species, which I call C. interruptus, is very easily recognized and has been figured by Prof. Townend Glover on his Plates of Lepidoptera. The head is white ; palpi inwardly and beneath white, outwardly dark brown. Thorax white, patagia bright brown. Hind wings and abdomen pearly gray. Fore wings bright brown with a longitudinal white median band obliquely interrupted at the middle of the wing by the ground color.
