This species, a beet feeder of long standing-, has in recent j^ears come to the front as an important enemy to sugar beets, and table beets are also affected. In 1899 and 1900 much injury was done to sugar-beet fields in Michigan, some having been practically destro3^ed while the plants were quite young. During 1900 much injur}^ was done in Colorado, the beetles appearing in swarms of millions ^nd practically killing plants of two or three weeks' growth. Older plants were considerably checked in development, but not destroyed. The next year beets were injured in South Carolina and Indiana. This is one of our commonest, most nearly omnivorous, and most destructive flea-beetles. It measures about an eighth of an inch, is cream-colored, with nearly black abdomen and eyes, and striped wing covers (fig. 8, h). The larva is white and slender, with light brownish-j^ellow head. It is an American species and of rather wide distribution, from New Jersey and Penns}^- vania southward to Georgia, and westward to California. The pale-striped flea-beetle, though a general feeder, is particularly fond of the foliage of beets and beans. Potatoes and corn it also injures very much, while considerable damage to melons and other cucurbits, tur- nips and other crucifers, tomatoes, peas, carrots, and eggplant has been observed. The beetles also attack strawberry, clover, cotton, oats, and peanuts, and injure the leaves of pear, as also pear grafts, b}^ eating out the terminals, thus stunting the growth of the trees. They sometimes do severe injury in three or four days. The species hibernates as a beetle, and appears above ground in the vicinity of the District of Columbia early in June; egg laying evi- dently continues through that month and to the middle of July, if not two or three weeks later; injury is usuall}' due to the beetles upon their firs
