The thorax is twice as wide as its length, and is much rounded on the sides, which are broadly margined; all the angles are rounded; there are two vague rounded basal impressions, and a scarcely perceptible medial elevation. The fifth joint of the antennae is longer than tbe fourth, the fifth to the eighth joints are equal in thickness, oblong, and the sisth is shorter than the adjoining ones; the eighth is a little shorter than the seventh, the ninth, tenth and eleventh are equal in length, and each is a little longer than the seventh and eighth united. 2. E. p n nc tu 1 atu s. Anobium punct. Lee, Proc. Acad., 1859, 284. California. Related to the preceding, but the thorax is more transverse, with the sides much less rounded, and the elytra are less densely punctulate; the disc of the thorax is obsoletely channelled behind the middle. The proportion of the joints of the antenna e seems scarcely different from E. mollis. 3. E. alutaceua. Philoxyfonalut. Lee, Proc. Ac. 1861, 352. California, one specimen. More elongate than the two preceding species, with the sides of the thorax considerably rounded, but the anterior angles more distinct, and less rounded; the disc is marked with a vague transverse impression in front of the middle; the elytra are scarcely distinctly punctulate. The joints, 5--8 are less unequal in length than in E. mollis and punctulatus; the ninth is equal in length to the three preceding united, and but very little wider. 4.
