The species in question {Tanymecus confertus Gj^ll.) was once notably injurious to sugar l)eet in Nebraska. It was observed by Professor Bruner first on cocklebur, lambsquarters, and smartweed, after devouring which it completely destroyed the beets in a 12-acre field. Injury b}- this class of insects in beet fields is by the beetles, the larvae feeding on the roots of weeds and wild plants. THE IMBRICATED SNOUT-BEETLE. {Epicserus imhricatus Say.) The imbricated snout-beetle is a common insect of the field, garden, and orchard, and capable of committing considerable injury to a variety of useful plants in- cluding sugar beet and various other vegeta- bles, such as beans and pease. It is one of our largest snout-beetles, measuring- nearly half an inch in length, and has the body covered with minute imbri- cated scales (whence the insect's name), the lighter portions ap- pearing brownish gray, and the darker light brown, forming a pattern as shown in figure 23, a^ and l. The head is prolonged into a short broad snout, with elbowed antennae and the elytra or wing covers terminate in a point. Both sexes are wingless. It is well distributed, occurring in most States, except the more northern ones, east of the Rock}" Moimtain range. It does not appear to be found north of the Upper Austral life zone. This distribution includes localities from the neighborhood of New York City south- ward to Texas and westward to Colorado and Utah. In addition to the plants that have been mentioned as furnishing food for this species, it has been observed doing more or less injury
