I have taken it upon beech and believe it to infest this tree. Dr. Packard and Prof. Riley have each found it infesting oak. 8. Agrilus interruptus, Lee. This species much resembles the preceding, but is somewhat smaller and mpre slender. Its colour is more of a bronze, and instead of the line of pubescence it has & minute golden dot toward the tip of each elytron. I have found it upon beech, birch and hickory, but do not find in my books any records of the trees upon which other collectors have found it. 9. Brachys aeruginosa, Cory. The larvae of this little buprestid have been found by Mr. V. T. Chambers (Packard. 1. c, p. 519) to mine in the leaves of the beech. The posterior segments are not so tapering as in the larvse of the species previously mentioned. The beetle very closely resembles the following in size and appearance. 10. Brachys aerosa, Melsh. (B. terminans, Lap) is rather a common beetle with us, and is found most frequently upon the bass- wood, but also occurs upon elm, beech, etc , and may mine in the leaves of all these trees. It has been bred by Prof. Gillette from the leaves of poplar (Can. Ent., vol. xix., p. 138). The beetle is only about one-sixth of an inch long, of a sub-triangular or narrow shield- shaped figure; general colour coppery, the elytra purplish and ornamented with pubescence, which forms a band across the tips. We have a larger species, B. ovata, We
