APPENDIX.

After this paper was in type, I received from the Davenport Academy of Natural Sciences, through the kind intervention of Prof. Herbert Osborn, of Ames, Iowa, the single type of Ceuthophilus utahensis Thom. (see p. 102), and append a description of it to render this paper more complete. It is not so closely related to C. valgus as I had supposed from the description and figure, but belongs rather in the near vicinity of C. uhleri and C. blatchleyi, though with the inferior sulcus of the hind femora not so exceptionally broad as in those species, and also with very different markings, in which respect it recalls rather C. pallidus. The measurement of the hind tibiæ given by Thomas is too great. The specimen was collected in alcohol, but has since been pinned.

Brownish fuscous with dull luteous markings; on the pronotum the fuscous borders all the margins broadly, the anterior and lateral margins very broadly, sending backward from in front a broad mediodorsal stripe nearly meeting the posterior bordering, and through it runs a faint median luteous thread; the posterior bordering throws forward on either side a subdorsal tooth embracing the posterior end of the mediodorsal stripe and leaving between the two a U-shaped luteous mark which connects the luteous disks of either side, the latter of which are more or less mottled with fuscous lines; the meso- and metanotum are heavily spotted anteriorly with partly confluent luteous spots, and the abdominal segments are more regularly margined anteriorly with luteous; legs warm luteous, the hind femora with the usual scalariform infuscations. The antennæ are moderately slender and more than twice, probably thrice, as long as the body, and the legs moderately long. Fore femora no stouter than the middle femora, a little less than half as long as the hind femora, scarcely more than a third longer than the pronotum, the inner carina with a moderately long preapical spine preceded by a shorter one. Middle femora with a single moderately long spine on the front carina and on the hind carina 1-2 short spines besides a moderate genicular spine. Hind femora nearly as long as the body, somewhat more than twice as long as the fore femora, moderately stout, only the distal sixth subequal, about three and a quarter times as long as broad, the surface with a very few raised points along the upper edge of the inner side, the outer carina considerably and subequally elevated, with about fifteen coarse but rather small subequal and inequidistant spines, the longest

not a third as long as the tibial spurs, the inner carina with a series of rather distant short spinules partially biseriate, the intervening sulcus broad, equal, and deep. Hind tibiæ rather feebly and broadly sinuate (this point is exaggerated in the original figure), a very little longer than the femora, armed beneath with a single long preapical spine besides the apical pair; spurs subalternate, the basal beyond the end of the proximal third of the tibia, nearly twice as long as the tibial depth, set at an angle of about 35° with the tibia and divaricating about 80°, their apical third or fourth considerably incurved; inner middle calcaria considerably longer than the outer, fully twice as long as the others or as the spurs, but somewhat shorter than the first tarsal joint. Hind tarsi about two fifths as long as the tibiæ, the first joint as long as the rest together, the second and fourth subequal, and each about twice as long as the third. Cerci rather stout, tapering regularly, about as long as the femoral breadth.

Length of body, 14.5 mm. ; antennæ, 31+ mm.; pronotum, 4.4 mm. ; fore femora, 6 mm.; hind femora, 13 mm. ; hind tibiæ, 13.5 mm. 1. Mt. Nebo, Utah, August, Putnam (Dav. Acad. Nat. Sc.).

:

CROSSOSOMA PARVIFLORA. A shrub, 4-8 feet high: branches covered with gray bark; branchlets slender, elongated, and often flexuous, sometimes straight and a little rigid; cortex yellow leaves elliptic-oblong, obtuse and mucronulate at the apex, pale green upon both surfaces, thickish, 1-nerved, 4-6 lines long, 1-2 lines broad: sepals 5, broadly oblong or suborbicular, 13-24 lines long: petals 5, oblong, 3 lines in length: stamens 15-20: carpels 3-4; follicles glabrous, reticulated, only 3-3 lines long. - Collected in the Grand Cañon of the Colorado, by Dr. Gray, February to May, 1885, but referred to Glossopetalon Nevadense, Gray; and at La Tinaja, Sonora, at 3,700 feet, by Mr. Hartman, 19 November, 1890 (no. 245).

ERIODENDRON ACUMINATUM, Wats. (Proc. Am. Acad. xxi. 418). Specimens apparently of this species, but representing other stages than those shown by the type, were collected in Western Chihuahua but without more exact locality. The older branches are armed with stout spreading spines 3-4 lines in length, while the younger ones, as Dr. Watson states, are unarmed; the young shoots and leaves are densely tomentose: the calyx deeply campanulate, an inch long, shallowly 5-toothed, glabrous and glaucous upon the outer surface, densely sordid tomentose within; teeth rounded, often split (perhaps in drying) petals linear, 5 inches long, 4 lines broad, very appressed silky upon one side of the outer surface, tomentose upon the side covered in the bud; glabrate upon the inner surface: stamens included. — The Mexican name is "Pochate." The fleshy white roots are eaten, the

fine cotton is used for making wicks for tapers of wild beeswax. This species is to be distinguished from E. tomentosum, Robinson, by its glabrous calyx and relatively broader leaflets.

ESENBECKIA HARTMANII. A shrub, 6-10 feet high: twigs thick, woody, covered with gray bark, leafy chiefly near the end leaves simple, alternate, oblong or somewhat obovate, entire, rounded or retuse at the apex, somewhat narrowed below to an obtuse or rounded base, thickish, green, nearly smooth and finely reticulated above, tomentulose and scarcely paler beneath; the largest ones 16-20 lines long, 8-11 lines broad; the others considerably smaller (8-9 lines in length); petioles short, soft pubescent, 1-1 lines long: inflorescences short, terminal upon the branchlets; fruiting pedicels 1-3 together, inch or less in length: the capsule tuberculately roughened, 9-10 lines in diameter; pericarp white, thin and chartaceous, rather irregularly ruptured upon dehiscence; seeds subglobose, smooth, black, 3 lines in diameter; scar white, narrow, linear, line in breadth. Collected in fruit at La Tinaja, Sonora, at 3,700 feet, by Mr. Hartman, 19 November, 1890 (no. 240). This species much resembles the Lower Californian E. flava, Brandegee, but differs in its smaller greener shorter-petioled leaves, and its smaller fruit with chartaceous and not. cartilaginous pericarp. The seeds of E. flava also are larger and have a much broader scar.

ILEX RUBRA, Wats. (Proc. Am. Acad. xxi. 422). Flowering specimens of this species, which was originally described in fruit, have been collected in an arroyo near Coloradas, by Mr. Hartman, May, 1893 (no. 513), and add the following characters: flowers numerous, in small aggregated thyrses, greenish white, 4-parted: calyx lobes ovate, obtuse, line long: corolla nearly 4 lines in diameter, about equalling the stamens; the lobes rounded.

DALEA LUMHOLTZII. Stems many, slender, puberulent, punctate with yellow glands, simple or sparingly branched, erect from a decumbent much branched suffrutescent base: upper leaves erect or ascending, 1-13 inches long, leaflets 17-27, linear, 2-2 lines long, nearly line in breadth, obtuse, slightly narrowed to very short petiolules, glabrous, glaucous and glandular-punctate upon both surfaces; the basal leaves numerous, shorter, and with considerably smaller almost filiform leaflets, silky under a lens: spikes ovate, capitate, 3-7 lines in length, becoming oblong, very densely flowered, covered with closely imbricated persistent bracts; the latter ovate or obovate, very abruptly pointed, silky upon the margins and especially near the somewhat narrowed base; glabrate and glandular-punctate upon the back,
