Observations conducted by the writer in the District of Columbia on this noctuid indicate that the name of " bean cvitworm " be- stowed by Ashmead on the larva in 1887 ^ and adopted by others,. Larva of Ogdoconta ciiwrcola resting on leaf of Helianthus tuberosus—3 times natural size. including the writer, is a misnomer. In the first place, it is not a cutworm and does not even belong to the group containing the cutworms; and in the second place, there is doubt if it ever does much injury to beans, the suspicion being that the real cause of injuries to beans which have been recorded was in reality the green clover worm (Plathypcna scabra Fab.), the larva of which super- ficially resembles this insect, and a species which occasionally does serious injury to leguminous crops, as in the year 1919. July 4-7, 1916, the larva was observed in the District of Colum- bia working on the lower surface of Jerusalem artichoke {Heli- anthus tuberosus) and on sunflower {H. annuus). Larvae rest habitually during the day stretched out on the midribs (Fig. 1), and when the plants are in shade they feed freely and " rag " the foliage badly. Unfortunately, for photographic purposes, the presence of this larva is often complicated by that of loopers and ^Ashmead, W. H.—Bui. 14, Div. Ent., U. S. D. A., p.
