But besides these it has been found on native cruciferae, such as Nasturtium palustre (Scudder), Barbarea vulgaris (Schwarz) and Cakile ameri'-ana (Hamilton V Messrs. Bowles, Andrews and others have found it plentifully on mignonette. Reseda odorata, belonging to a neighboring family, and it has many times been reported both in this country and in Europe on Tropacoluni, one of the Gcraniaceae ; but as the common name of this plant. Nasturtium, is the botanical name of one of the Cruciferae given above, this needs special verification. Specimens that I reared re- fused to cat a {rrowing plant of shepherd's purse (Capsella). In Europe it has been found on the following genera of Cruciferae: Brassica, Sinapis, Nasturtium, Ilcsperis, Matiliiola, Cheiranthus, Erysimum, Lepidium and Raphanus. Also, as with us, on Reseda, and, according to Riley, it has even been found on a upecicc of Salix in England.
