Of numerous insects distinctive of the more southern palmetto the most conspicuous is a longicorn beetle, _Agallissus chamaeropis_ Horn, the larvae of which bore in the leaf-bases. The more common _Inodes_ is inhabited by the allied genus _Zagymnus_, though another species of _Agallissus_ is reported from Texas, where the native _Inodes_ is of the smooth-trunked type. Footnote 3: =Inodes vestita= sp. nov. Trunk about 45 cm. thick at base, columnar or tapering upward; surface rimose, the chinks commonly 5 mm. wide and 20 mm. apart. Leaf-bases torn into very numerous, fine, hair-like, light reddish-brown fibers, a few much coarser than the others and measuring from .6 to 1 mm. in diameter. The epidermis separates into delicate membranous shreds, the surface of which is delicately pitted and sparsely beset with brownish hairy-margined peltate scales. Petiole 10 cm. or upward in width below near where it begins to split, 4.5 cm. wide at base of ligule; 3 m. long, concave above; blade 2.13 m. long, 2.50 m. wide, composed of about 60 segments, the apical united more than two-thirds their length, the basal for less than one-third; apical segments 4.5 cm. wide, deeply divided above, a long fiber terminating both the longer and the shorter ribs. As shown by the rimose bark this species affords a rather extreme instance of the gradual enlargement of the trunk at a distance from the growing point. Numerous leaf-bases remain attached to the trunk in the greenhouse as they would not do in nature, since they are torn loose except for a few fibers at the extreme sides. Footnote 4: Dr. Rose also kindly permits the use of the following field notes and measurements showing that _Inodes Rosei_ is also a taller and more slender tree than _I. Uresana_. “Trees 6–12 or sometimes even 18 meters high, the long slender naked trunk 15–20 cm. in diameter, crowned with a large cluster of leaves; petioles 60 cm. or more long, flat on the face, pubescent, but becoming glabrate; blade pale green, 8 cm. or more in width, strongly keeled, more or less clothed beneath with brown scales on the large veins; segments cleft to below the middle, 25 mm. or less wide; inflorescence in large branching panicles 60 cm. or more long; fruit spherical, 18 mm. in diameter, blackish or dark blue when mature.” “A very common tree east of Rosario towards Mazatlan, also extending all the way from Rosario to Acaponeta; especially common on the low hills, and east of Rosario toward the mountains. This species is of considerable economic importance, the trunks being used in building fences, corrals and huts, while the leaves appear as thatch on a majority of the houses of this region.” Footnote 5: Hist. Nat. Palmarum 2: 29. Footnote 6: Roemer and Schultes treated _Martinezia_ as a synonym of _Oreodoxa_. Footnote 7:
