This species is well known to attack both Astragalus and Aragallus, as Avell as various other related plants, including clover, cowpea, alfalfa, coffee bean (Cassia), bur-clover, Caragana arhorescens^ Rohinia viscosa, Melilotus italica, and Glycyrrhiza lepidota. It has also been observed on oxalis, and on cotton associated with the common and more destructive cotton or melon aphis. Certain of our correspondents have remarked on the occurrence of ladybirds and ants on infested loco plants, conclusive evidence in the case of the ladybirds, Hippodamla con oergens Guer., that aphides were jDresent. The present species has a considerable literature, having been de- scribed in 1857 and afterwards treated more or less fully by Monell, Thomas, Oestlund, Cowen, Osborn, Hunter," and Sanderson. A somewhat complete account of this aphis was given by Sanderscm in 190G,'' including a consideration of its food plants and descriptions of different stages as well as references to literature. Still other bibliographical references have been given by Hunter.'^ This species is evidently of foreign origin and was first noticed in this country at St. Louis, Mo., by Monell in 1870. THE MEAL SNOUT-MOTH. fdrinalis L.) During July, 1907, a colony of the larva of this beautiful pyralid moth was observed by the writer breeding in the roots of Astragalus 7noUissimus received from Hugo, Colo. Since the species is of cosmo- politan distribution and commonly found in most barns, storehouses, and even in dwellings, it can not be posi- tively stated that it attacks loco roots in the open, but it quite likely infests the dead roots. Frequently this spe- cies breeds in clover hay, after the â , ^ ,r, ,â ^ â manner of the clover-hay worm,- to Fig. 13.âMeal snout-moth {Pt/rahs fan- . . i i * i i naUi<): a
