The black blisterlieenc (fig. 19) is a familiar object to nearh' everj-one from its occurrence on golden-rod, aster, and related wild plants, while the farmer is quite too well acquainted with it as an unwelcome visitor to his potato patch and to various other vegetables. Flo- rists know it under the name of "aster bug," from the severe injuries which it does to asters and which they are unable entirely to prevent. It is uniformlj- black, without polish, and its length varies from a little more than a quarter to half an inch. It is well distributed in the region east of the Rocky Mountains, and does most injury between the Atlantic States and Texas. Its time of appearance is more or less coinci- dent with the blossoming of the golden-rod, from June to October according to locality, and as a rule it appears later than other species. It is one of the worst insect ene- mies of potato, beet, and aster, jind is also destructive to carrots, beans, cabbage, corn, mustard, clematis, zinnia, and other flower- ing plants. THE ASH-GRAY BLISTER BEETLE. {Macrohasis nnicolor Kby.) This is one of our commonest Eastern species (fig. 20), and although most destructive to beans, peas, and other leguminous plants, is also a serious enemy of beets, potato, and tomato, and attacks besides sweet potato
