Eggs.—These are smaller and lighter colored than Sausetia olese. Larvse.—Are long, oval, light yellow, darker down the center, and can be dis- tinguished from the larvae of oleiv in not having the four reddish-brown marks upon the dorsum. Like other species of that produce but one generation a year, their development is slow. They generally hatch in June and locate upon the leaves, where they go through their molt, and then move to the young wood. In the spring they grow rapidly and throw off great quantities of excrement, into which the spores of the black smut {Fumago aalicinn) adhere and grow, injuring the health of the tree and the market value of the fruit. On apricot, prune, plum, cherry, peach, pear. This species is commonly known in this State as the brown apricot scale and is usually associated with E. pruinosum. The parasite Comys fusca has held this scale in subjection for many years, usually accom- plishing the work the second year after a colony has been FIG. 16. Eidecanium armeniacum (Brown Apricot Scale). Showing scales on prune branch; about natural size. Eulecanium cerasorum Ckll. This pest was first noticed in this State in 1904, a party having brought in a branch of English walnut which was quite thickly infested with the scale. Since then it has been found on pear trees.
