In his re- port to the Department of Ag-riculture for 1879, Prof. J. Henry Comstock, entomolog-ist of the Department, describes a new clover pest then recently discovered, called the Clover Stem Borer. The accompanying- illustration will enable the reader to identify the eggs, larva?, pupa, the adult borer and also the manner in which the eggs are laid in the stalk. It seems to be identical with an insect affecting the fall wheat in Kansas and perhaps other sections, and hence is not peculiar to clover. The female lays her eggs in June, ac- cording to Prof. Cook, piercing the stem with her jaws and pushing her eggs clear into the pith. The larvae feed on the pith downward, forming a burrow about six inches long. The pupa is formed at the bottom of this burrow and shortly after- wards the full}^ developed beetles begin to appear, emerging from the hollow stems from August to October. There is but one brood each year. The beetle hibernates and waits until the plants are in their full vigor in June before depositing her eggs. It will readily be seen that the Western method of cutting clover the last of June or the first of July, and then either pasturing or cutting the second crop for seed will give small chance for this pest to increase. Recent discoveries, however, have shown that a stock of the borers may be kept up indefinitely, from the fact that it lives on quite a number of plants besides clover. It has been found in the sweet clover,.in wild thistles, wild lettuce, yarrow and in timothy. It has, however, several parasites, and there is but little danger of it ever becoming a destructive pest. Clover Leaf Beetle, {Phytouumus pun iatus). This, like many of our destructive insect:,, is stated by Prof. Cook to be an imported species, common in Germany, prevailing in Ca
