NOTES ON FLEA-BEETLES. Among other injurious forms of insect life that were noticeable by their numbers during the season of 1900, flea-beetles of several species occupied an important place. Some of the injurious forms which were attached to special plants and some of the more striking instances of injury by species of omnivorous tendencies will be mentioned in connection with other observations that were made concerning them. During 1901 some species were injurious, but, as a rule, not so abundant tmd troublesome as in the preceding year. The Pale-striped Flea-beetle ('V//.s'7'/v?r/ hJandn Mels.).—The pale-striped flea-beetle was one of the most abundant and troublesome forms dur- ing the year 1900. In the latter half of May and early June it was noticed by the writer and others in greater abundance in ^Maryland and Virginia near Washington than in any previous year, and was concerned in inj iry to beans in several localities. It was reported to be troublesome to the same crop at Woodside, Md., and St. , by Messrs. Olds and Pratt of this Department, respectivelv. The lat- ter reported that during June it did great damage to pole and bush Lima beans, while the ordinary fleld or garden beans were scarcely touched. In som
