Fifth report of the United States Entomological Commission, being a revised and enlarged edition of Bulletin no7, on insects injurious to forest and shade trees . ght to the outer margin forward of the tip,and gives off from its middle on the outer side a very oblique branch which runs tothe outer margin, its tip producing a slight angular projection of the edge of thewing, and the whole space on the outer side of the rib vein beyond this branch is moreopaque than the rest of the wing and of a smoky yellowish color. From its inner side therib vein sends off three simple obliqueveins, the last one of which ends inthe extreme tip of the wing. Thehind wings have an angular pointon their outer side beyond Lhe middle,and a longitudinal rib vein, which,forward of its middle sends off abranch almost transversely inward,its tip curved backward. The antennjB are short, thread-like, and com-posed of four or five small joints. Itwill hence be seen that this insectis a true Chermes—the first species ofthis genus that has been discoveredin this country. (Fitch.) 146. The pine-leaf (Fitch.) Order Hemiptera ; family Coccid^..

(Fitch.) 806 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. This insect is injurious in the Western States, according to Riley,who describes and figures it in his Fifth Missouri Report. The diseaseto which it gives rise is sometimes called the white malady. Rileystates that it produces two broods a year in Missouri, i. e., one in Julyand again in October. It occurs on the white pine, red pine, Bhotaupine, yellow pine, and Oembra pine, and sparsely on dififerent speciesof imported pines. I have also noticed it at Brunswick, Me.
