A BIOLOGICAL JOURNAL PUBLISHED QUARTERLY. Jig OF ay A BIOLOGICAL JOURNAL MOL. LV. APRIL, 1893. No. 1. DR. ALBERT KELLOGG. The name of Kellogg is inseparably connected with the botany of California. Coming to this State in 1849, at the age of thirty-five, he lived for nearly forty years in the midst of a rich and varied flora. He published at various times during his residence, several genera, two hundred and fifteen species,* and several named varicties. The lapse of time and better knowledge have left valid less than sixty of these, but con- sidering his isolation, lack of books and herbarium this proportion contrasts very favorably with the work in California of some botanical writers of much greater pretension. During the years 1877-1883 publication by the California Academy of Sciences ceased, and with the exception of a few which appeared in a San Francisco newspaper, the Rural Press, the species described by him thereafter remained in the herbarium of the California Academy of Sciences with the MS. diagnoses. Several of these, as unanus angustatus, Spheralcea fulva, Calyptridium nudum, etc., have been described, either wholly or in part, from the types of Dr. Kellogg’s unpublished species, and no mention made of his work. He was one of a little band of seven who met at 129 Mont- gomery Street, in the office of L. W. Sloat, one of their number, on the fourth day of April, 1853, to found by the dim light of candles, which they had brought in their pockets, the California Academy of Sciences, now grown to proportions of which they could have hardly dreamed. When he died, March 31, 1887, he had long survived the rest. * An ‘annotated list of Dr. Kellogg’s species is to be found in Bull. Cal. Acad., Vol. 1, pp. 128-151. 2 Colorado Plants. [ZOE To the end of his life he was closely identified with the organization, which he loved with the love of a father. All visitors to the Society in the later years of his lifetime cannot fail to recall his familiar presence at the drawing-table in shirt- sleeves and red-backed vest, or, as in his hours of relaxation, leaning back in his chair with the stem of a cob pipe between his lips. He retained his sight marvelously, making to the last all his studies and drawings with a small hand lens, and finding any aid unnecessary to his reading and writing. His hair was just beginning to change from brown to gray when he died. His personal character was above reproach; no one ever imputed to him falsehood or unfair. dealing. His botanical statements, though sometimes erroneous, were true so far as he was concerned, and always made in good faith; but. he was a dreamy, imaginative man, full of poetic fancies, which often in descriptions caused him to dwell unduly upon some point which caught his fancy. His habit of tracing ‘* correspondencies ” between the material world and its organisms and the mental states of man, often appeared in his botanical writings. The first description of ‘‘ Marah,” for instance, was followed by a small sermon on the “ bitter waters’”’ of affliction, and to the type of Ouercus Morehus is appended the following note: ‘‘Abram’s Oak named from the circumstance of Abram’s first encamp- ment in the oak groves of Moreh, on his journey to Egypt (Egypt in correspondential language signifies Natural Sciences).”’ His childlike enthusiasm and unworldliness impressed all who. met him, He asked of the world only the means of simplest living. He lived a happy life and died respected. Would there were more like him. NOTES ON SOME COLORADO PLANT'S. BY ALICE EASTWOOD. RANUNCULUS ALISMASFOLIUS Geyer. This is described in Coulter’s Manual as having leaves with entire margins. This is misleading; for they are as often dentate with scattered teeth, © RANUNCULUS MACAULEYI Gray. This varies on every moun-_ tain range where it has been found. It grows along the edge of _ VOL. Iv. | Colorado Plants. 3 snow banks, and the buds can often be seen under the thin crust of melting snow. The flowers vary from an inch or more in diameter to a half inch orless. Inthe San Juan Mountains, above Silverton, it is abundant along the edge of snow banks. The leaves are three-toothed at the truncate apex and entire below; the calyx is thickly covered with soft brown wool. Specimens from the Elk Mountains, above Irwin, have the petals usually entire, but occasionally flabelliform, leaves almost orbicular and crenate nearly to the base, the silky wool dense on the calyx. The form from the La Plata Mountains has the calyx either densely or sparingly hirsute; the root leaves oblong-lanceolate; stem leaves not cleft as in the other two forms. RANUNCULUS GLABERRIMUS Hook. Specimens of this from Mancos have cauline leaves entire as well as deeply 2—-3-lobed, akenes plainly hispid. I have found no plants with three large blunt teeth at the apex of the leaves. DELPHINIUM OCCIDENTALE Watson. This varies greatly. At Steamboat Springs, in Routt County, it is one of the commonest © plants; but rarely could two plants be found with flowers colored alike. ‘They ranged from dark blue to white, and the forms between, where the two shades mingled, were mottled and striped, one part colored blue in one flower, white in another, so infinitely varied that to collect all forms was impossible. Usually it is found at subalpine elevations and is dark blue. I have specimens from above Irwin, in the Elk Mountains, in which all parts of the flower have become blue, bract-like petals. AOQUILEGIA ECALCARATA Eastwood. ‘This has been collected in Southwestern Colorado in but one limited locality, about twenty-five miles from Mancos, near the head of Johnston Cafion that forms a branch of the Mancos Cafion. It was abundant under an overarching rock that even late in August was still wet with the alkali water that oozed from it. The plants were growing in the sandy soil, loosely branching and also climbing up the rocky wall, apparently seeking moisture. The few flowers still in bloom were on stems that clung to the rock, but the plants were full of dry seed pods that indicated their earlier abundance. The pubescence is glandular and the flowers pink or white. 4 . Colorado Plants. | ZOE Mr. Alfred Wetherill, who discovered it, reports it also from Southeastern Utah in similar situations. ARGEMONE. ‘There seems to be doubt as to the existence of Argemone hispida Gray as a species, and in Colorado, if it has ever previously been collected, it has been merged into A7gemone platyceras Link & Otto. It is excluded from both Patterson’s and Oyster’s check lists, but whether included under 4. Alaty- cerasor A. Mexicana var. albiflora has not been learned. Judging from the specimens of 4. Mexicana var. albiflora now in the herbarium of the California Academy of Sciences, 4. platyceras is much nearer A. Mexicana var. albiflora than A. hispida. They are alike in the stem and foliage, glabrous and glaucous, except for the spines which are scattered on the stem and on the veins and margins of the leaves. The veins are also outlined with white, immature pods seem the same; the stamens differ slightly, A. Mexicana var. albiflora having broad filaments abruptly narrowed to the anther; A. platyceras with filaments narrower and tapering to the anthers which are longer and narrower than those of A. Mexicana. There is some variation in A, platyceras in the manner of branching, size of the pods, and number of spines. There are forms that closely resemble A. corymbosa, differing chiefly in having larger pods and the leaves longer, with deeper lobes and blunter at the apex. Argemone hispida Gray. ‘This is distinct from both A. Mext- cana var. albiflora and A. platyceras, and shows so little variation that specimens from Colorado and California have no appreciable difference and agree with the original description as given in Gray’s Plante Fendlerianz. It differs most noticeably from the other two in the pale green foliage densely covered with short crimped bristles, short spines on the margins and veins of the leaves and very dense on the stems. The pod is densely covered with slender bristles of varying length, instead of the coarse, horn-like spines peculiar to the pod of A. platyceras. In growth A. hispida is more compact and the flowers are on short peduncles seeming almost sessile. The seeds of 4. platyceras havea light-colored, pominent rhaphe and the coat honey-combed. A. hispida has the less prominent rhaphe of the same color as VOL. Iv. | Colorado Plants. 5 the coat, which is less deeply pitted; the seeds are larger. The pods of A. hispida are ovate, and when they dehisce the seg- ments are acuminate. In A. platyceras the pods are veiny and the segments acute. I have seen no intermediate forms which might connect these two that seem so different. ERYSIMUM ASPERUM DC. ‘This widely distributed speciés, as found on the plains, is low and stout, with pods often four inches long, numerous and perpendicular to the stem. The pods are stiff, and, projecting as they do, remind one of the spears of a Macedonian phalanx. The flowers are yellow. The variety at Silverton, in the San Juan Mountains, has the color of the flowers from pale yellow, almost white, to orange on the one hand, and through shades of pink and crimson to purple on the other. These different shades were found in one patch and seemed to indicate that the common yellow form had become mixed with a purple variety. The mountain form is more slender than the prairie plant, and the pods are ascending. ArABIs Horspaiiit Hornem. This is one of the most puzzling of the western Cruciferze because of its great variety of forms. If there are any plants of 4. Holbellii with one row of seeds in each cell, wherein does it differ from A. canescens, which also has stellate pubescence and deflexed pods? The division, if A. canescens is a good species, should be thus: Pods deflexed or spreading, seeds in one row, A. canescens; seeds in two rows, A. Holbelliz. If pods containing both one and two rows of seeds are found on the same plant of 4. Holbelliz, then A. canescens ought to be included under 4. Holbeliii. Including under 4. Hfolbellii all the forms that are perennial and have pods deflexed or spreading, with two rows of seeds in each cell and pubescence generally stellate, the following forms should be described in order to make the species better understood: 1. From Mancos, Colo. Stem simple, stout, tall, thickly clothed at base with white branching hairs, but not stellate, above glabrous and glaucous; radical leaves from spatulate to oblanceolate, sparingly dentate or entire; cauline leaves sagittate- clasping, pedicels spreading upwards and outwards, pods deflexed or horizontal, glabrous; winged seeds, two rows in each cell, petals twice as long as the stamens, erect. 6 Colorado Plants. [ZOE 2. Fiom Mancos. Similar to No. 1, but canescent with close stellate pubescence; pedicels strictly deflexed with scattered stellate hairs, pods sparingly hairy along the margins. This was also collected in Navajo Cafion, a branch of Mancos Cajfion. 3. From Mancos. Stems slender, several from the root, canescent with close stellate pubescence; radical leaves from spatulate-dentate to oblanceolate, entire; upper part of the stem and pods smooth and glossy, pods on spreading pedicels, two rows of winged seeds in each cell, flowers small. 4. From Mancos. Similar to No. 2. except that the cauline leaves are oblanceolate, sessile at the lower part of the stem, and sagittate above only. . oe 5. From Southeastern Utah. ‘This branches at the root and also above, and is chiefly distinguished by the short spreading pods not more than an inch in length. 6. From Central City, Colo. This branches from near the base with many slender stems, small lanceolate sessile leaves, with scattered bristly hairs on the margins. ARENARIA FENDLERI Gray. This is found at Grand Junction with short leaves and straw-colored flowers. SIDALCEA. This is described as having beakless carpels. The two species found in Colorado, S. candida and S. malvefiora, have carpels decidedly beaked, wrinkled, and veiny. SPHARALCEA RIVULARIs Torr. This has been collected with two well marked forms. The plant seen in the Uncompahgre Cafion, near Ouray, was almost a bush three feet or more tall, with many leafy stems from the. root, lower leaves a foot long, slightly lobed and crenate, hispid with stellate bristles, upper ‘stem-leaves with deeper lobes irregularly toothed; flowers nearly two inches in diameter, white and few among the large, broad leaves which thickly clothe the stem. At Steamboat Springs, in Routt County, Colo., Spheralcea rivularts is abundant on a mountain side not far from the town. This variety branches into many flowering erect stems, leaves not more than three inches long, deeply lobed into acuminate _ divisions which are sharply dentate or laciniate, the large rose- colored or white flowers are crowded along the almost naked - peduncles. . vol, Iv: | Colorado Plants. x OXALIS CORNICULATA L. var stricta. ‘The common form found at Denver is slender, loosely branching upwards, leaves scattered; the alpine variety shows a modification due to environment, and becomes low and almost prostrate, leaves crowded along the short rather stout stems. . PacnystTinA Myrsinires Raf. ‘This is described in Coulter’s Manual as having green flowers. All that I have seen have purple flowers. MENTZELIA ALBICAULIS Dougl. There ate two varieties of this common species. One is the widely distributed form with slender stems and linear-lanceolate leaves pinnatifid into narrow, linear lobes. The other which I name var. INTEGRIFOLIA is low with short, stout branches, or in more favorable situations becoming a foot high, leaves ovate-lanceolate or even broadly ovate entire or rarely coarsely and remotely dentate, petals not exceeding the stamens, pubescence somewhat viscid as well as barbed. This grows on the adobe desert and blooms almost as soon as it is up. It branches from near the base, and the leaves seem long and crowded on the short stems; but on the older specimens the stems elongate and the leaves are less crowded. MENTZELIA MULTIFLORA Gray. At Grand Junction this variable species was found growing on a slaty hillside. It branched diffusely from the base and above, making a globular plant like a tumble weed. The stems are white, slender and sinuous; leaves small, about an inch long and pinnately parted into narrow, linear divisions; flowers small, not an inch in diameter, yellow. Along the McElmo Creek the plants have lobed leaves from one to three inches long, stems less numerous, stouter and straighter than the preceding, flowers larger. MENTZELIA NUDA Torr. & Gray. This varies in the manner of growth and size of the flowers. The Denver form is loosely branched from near the base upwards, and the flowers are large, from one and one-half to two inches in diameter, distinctly pedunculate. The form from Southwestern Colorado - has an erect stem simple up to the inflorescence; the branches are usually short with the almost sessile flowers bunched at the ends; flowers about an inch in diameter. 8 Colorado Plants. [ZOE ANGELICA WHEELERI Watson. ‘This is quite common in Colorado, at middle elevations along streams. Specimens have been collected at Crested Butte, Coloraco Springs, Chiann Cafion, and at Central City. % APLOPAPPUS SPINULOSUS DC. and A. Gracinis Gray occur through Southwestern Colorado, and there seem to be inter- mediate forms connecting the two. A. spinulosus is exceedingly variable, and the forms might easily be mistaken for new species in different localities. ACTINELLA RicHARDSONII Nutt. This was collected by Miss Alida P. Lansing, in South Park, agreeing with the description of the type and different from the form var. floribunda common in Colorado. It has a few large heads, and the stems are shorter and stouter, while the variety has a cyme of many small flowers, and leaves in almost filiform divisions. ACTINELLA GRANDIFLORA Torr. & Gray. This has the involucre from densely white woolly to almost glabrous, heads from one to three inches in diameter, leaves occasionally simple and linear, more frequently few to several lobed. Stems leafy or nearly naked and scape-like. CNICUS ERIOCEPHALUS Gray. A few plants collected on Mt. Hesperus, of the La Plata Range, in Southwestern Colorado, seem to approach C. Parry so closely that it is uncertain under which species to place* the plants. The foliage is nearly glabrous, the involucral bracts have no lacerate fimbriate tips, the woolly hairs on the bracts are not dense, the flowers are light pink and in an erect glomerule. Cnicus DRumMMonNDII Gray var. BIPINNATUS n. var. This is either a variety of C. Drummondii or a new species. At present it seems better to consider it in the former light, and give the characters which distinguish it from the type of the species. Stems several from the root, two feet or more high, sparingly tomentose along the stem and the margins of the leaves; leaves divided into many linear lanceolate divisions that are themselves parted into similar lobes of variable length, the lower lobes often as long as the leaflet; the lobes are linear and about one-fourth inch VOL. IV. | Colorado Plants. . 9 wide, one to three inches long; heads small and narrowly oblong; lower bracts of the involucre with weak prickles, upper ones purplish, acuminate and. tipped with a weak point, scarious; flowers much exserted, heads several at the ends of the leafy, spreading branches. FRAXINUS ANOMALA Torr. In this queer ash the leaves are nearly always simple and entire, the three-lobed or divided ones being rare. It is found at Grand Junction and on Mesa Verde, in Colorado, and through Southeastern Utah. PHACELIA SPLENDENS n. sp. Annual, erect, about a foot high, usually simple stemmed, sometimes branching from near the base; stems purplish, glandular or glabrous; leaves ovate- lanceolate in outline, pinnately parted into three or four pairs of alternate divisions that are either crenate or bluntly lobed and | oblique at base, nearly glabrous, but glandular on the rhachis; scorpioid cyme with a long naked peduncle; flowers on short pedicels; calyx white-hirsute, and slightly glandular, divisions linear-lanceolate, 1 mm. wide, 4 to 6 mm. long, veiny in age, with longitudinal nerves, slightly surpassing the ripe capsule; corolla bright blue, rarely white, about 1 cm. in diameter, divisions obtuse; stamens and style conspicuously exserted, > or 8 mm. beyond the corolla; capsule veiny, glandular, and hirsute; seeds with the central ridge very prominent, cymbiform, favose over the whole surface, but not corrugated. This beautiful Phacelia belongs to the Euphacelia, near. P. glandulosa and P. Neo-Mexicana. It grows on the adobe desert soil, and while not along the edges of irrigating ditches or washes, it was comparatively near by. Collected at Grand Junction, May, 1892. PENTSTEMON MOoFFATII n. sp. Stems several from the root from one to two feet high, erect, scabrous below, glandular hirsute above; radical leaves crowded, ovate-spatulate, entire, decurrent along the petioles which equal or surpass the blade in length; lower cauline leaves spatulate with long, broad petioles which are connate-clasping; upper, ovate-lanceolate, closely sessile by ~acordate base obscurely dentate at the apex or entire; thyrsus interrupted, the many-flowered clusters about an inch apart; 10 . : Colorado Plants. | ZOE _ calyx of linear-lanceolate divisions hirsute, glandular, and ciliate with crimped hairs; corolla purplish blue, hardly bila- biate, spreading lobes orbicular; two of the stamens inserted at the base, the other two half way up the limb, nearly on a line with the sterile filament which is moderately bearded down the side with hairs pointing downwards. In the descriptions of Penstemons no attention has been paid to the insertion of the filaments which may prove of use in determining species that seem closely related. This belongs to the Genuini and is nearest P. albidus of which it may prove to bea variety. It differs from PP. albidus in being less glandular, the shape and attachment of the leaves, the more interrupted inflorescence, the color and shape of the corolla, the denser beard of the sterile filament and ‘in the explanate anthers which in P. albzdus are orbicular and in P. Moffatiz, oblong. It was collected at Grand Junction along the railroad to the coal beds, and I have named it in honor of David H. Moffat, ex-President of the D. & R. G. R. R., whose courtesy and kindness I wish to acknowledge. ABRONIA TURBINATA Watson. ‘This varies in the fruit, the wings in some specimens being well developed; in others, more or less aborted. ATRIPLEX CORRUGATA Watson. This was collected at Grand Junction, in May, 1892, with both moncecious and dicecious plants. The plants collected the previous season from which the description was made were all dicecious. ‘ERIOGONUM BREVICAULE Nutt. This is the plant which Nuttall named 4. campanulatum, but which with £. micranthum Nutt. Dr. Gray reduced to £. brevicaule. He says that these three species are not permanently distinguishable even as varieties. The descriptions omit the most striking feature of the flower, the urn-shaped perianth, constricted at the throat and angled along the sides. All the flowers examined on the Grand Junction plants have perfect flowers. ERIOGONUM GLANDULOSUM Nutt. This has been but rarely collected, and the description isimperfect. My specimens agree with Nuttall’s description of Oxytheca glandulosa under which VOL. IV. | Colorado Plants. II name it was first described. The following characteristics not given in Nuttall’s description, seem worthy of note: ‘The bracts within the involucre which in Eriogona generally are so small as to be seldom noticed, in this species are larger than the teeth of the involucre, which therefore seems to be double; the capillary branchlets are geniculate about the middle, usually bending towards their axis. It is rare at Grand Junction, but was common on a hill-side in Montezuma Cafion in Southeastern Utah. ER1oconum sAtsucinosum Hook. There are two forms of this that are strikingly unlike, but specimens with peculiarities of both are to be found on the same plant. One has the involucre sessile in the axils of the leaves or the forks of the stem and appears close and compact; the other has the heads at the ends of hair-like peduncles of from one to three inches long; the sessile heads are often found as well as the long pedunculate ones on these specimens which usually have narrower leaves than the first form. ‘The pedicels aré generaily purple and often the whole plant has the same color. Found at Grand Junction and along McElmo Creek, in Colorado, It also grew on rocky, rounded hills in company with 2. glandulosum and £. divari- catum, in Montezuma Cajfion, in Southeastern Utah. Er1oconum microtaEcum Nutt. The varieties of this species are puzzling, for it seems hard to know where and how to draw the line between it and £&. corymbosum Benth. The flowers of the two species and their varieties differ so little as to furnish obscure distinguishing marks. The chief marks of difference are in the manner of growth and flowering. It seems best to arrange them in this way until more material can be obtained. : The type and the variety effusum have been sufficiently described; but there is a variety on the mesas at Durango, which seems to be undescribed. I propose to name it var. RIGIDUM - because of its stiff manner of branching and flowering. Stems woody, one to ‘two feet tall, branching from the base and also above, with erect branches tomentose throughout; leaves narrow, ‘linear, revolute, numerous along the stem, about 2 cm. long; 12 Colorado Plants. — [ZOE corymbs umbel-like, small and compact on naked peduncles from 2 to 8 cm. long; the branchlets are usually perpendicular to the axis and the involucres are sessile, perpendicular, erect, and secund on the upper side. ERIOGONUM CORYMBOSUM Benth. JLeaves from narrowly linear 5 mm. wide to oblong 2 cm. wide, crenate-undulate on the margins and densely white-tomentose on the under surface. The leaves are either clustered near the root or are along the stem to the long, naked peduncle of the corymb, which is usually spreading but sometimes almost capitate. The stems, branches, and branchlets are densely tomentose and seem coarse compared with the var. J/eptophyllum. This variety has long, linear- lanceolate leaves with revolute margins, somewhat tomentose below, almost glabrous above, corymbs on naked peduncles, barely surpassing the leaves, loosely branched, sparingly flowered. The species is usually found on slaty hill-sides, while the variety is found in loose soil under the pifions and cedars or along the banks of dry alkali streams. It is uncertain whether the variety belongs to £. corymbosum or to E. microthecum. SMILACINA STELLATA Desf. This is described as having blue-black berries. All that have been seen in Colorado, from observations extending over several years, have the berries at first green, striped with red, but when fully ripe they are red all over. The species in California has been collected with the red- striped berries. Doubtless, if collected or observed later in the season, the berries would be found as in Colorado. ; FRITILLARIA ATROPURPUREA Nutt. This was collected at Mancos with both perfect and staminate flowers, showing a tendency to become dicecious. No pistillate flowers were found. CaLocuortus Nurrau Torr & Gray. This usually has white petals, but at Grand Junction it varies through all the shades of pink to crimson-purple and also white. C.

The following trypetid was collected by the writer, December 31, 1892, at Chacaltianguis, a river town about seventy-two Mexican miles up the Papaloapam River from Tlacotalpam. It was taken with other diptera and various insects, by sweeping the undergrowth in the edge of the woods back of the town. This trypetid belongs, by the markings of its wings, in the genus Euaresta. It has four bristles on the scutellum, which does not, however, preclude it from this genus, as some of the species placed here by Loew also possess four scutellar bristles. But the shape of the wings is distinctly different from that of the wings of Euaresta. They are very broad on the median one-half of their length, then slightly taper to a blunt apex. I shall leave the form for the present, however, in Euaresta. The species is very similar to £. Mexzcana Wd. and £. melano- gastra Lw. (syn. of preceding ?) but differs from both in having four bristles on the scutellum; and it also differs from all the species of Euaresta in another character which must be men- tioned, and which was considered by Loew of generic importance, that of the third longitudinal vein being bristly almost to its termination. EUARESTA LATIPENNIS nov. Sp. ?. Front more than one-third width of head posteriorly, evenly narrowed to about one-third width of head at base of antennze, pale silvery on borders, the rest being taken up with the wide, very dilute tawny frontal vitta, which also has a silvery reflection. Antennz very dilute tawny, third joint about one and one-half times as long as second, second joint with a small bristle anteriorly and sparsely clothed with minute bristles; arista thickened basally, where it is concolorous with antenne, and shows a basal joint, blackish on remaining portion. Eyes (in dry specimen) dark green, or dull purple, according to change of light. Frontal bristles five in number on each side, not including the long posteriorly directed pair on vertex; of these the anterior 14 oe New Trypetid. [ZOE three on each side are nearly straight and directed forward, while the hinder two are curved and directed backward. A pair of curved, divergent, anteriorly directed ocellar bristles. Face and palpi pale silvery, the palpi sparsely clothed with small bristles | on lower portion; cheeks, occiput, and proboscis dilute tawny, occiput above bordered with a row of whitish bristles. Thorax slightly silvery cinereous, with three golden brown vitte, clothed with whitish bristles and hairs; humeri and pleurz concolorous; scutellum nearly concolorous, rather triangular in shape, with four bristles, the anterior pair longest, the apical pair hardly decussate., Abdomen brownish, flattened, curved under, some- what ovate in outline, rather pointed behind, quite sparsely clothed with short bristly hairs, and with longer bristles on hind margins of segments. Legs pale brownish fulvous, claws short and blackish. Wings broad, rather long, from apical three- fourth tapering almost equally on anterior and posterior borders toa blunt apex. Picture of wings almost the same as that of E. Mexicana, figured by Loew in Monographs, iii, pl. x, fig. 28. Differs from the figure only as follows: Second vein ends about in middle of margin of hyaline spot third from tip on anterior border; of the three marginal hyaline spots of second posterior cell, the two end ones are somewhat elongated inward like the middle one; the proximal one of the two costal hyaline markings in marginal cell does not extend inward below the second longitudinal vein, or is represented by only the merest dot, and the distal one does not quite reach second vein; one (the right) wing shows two hyaline drops about middle of discal cell, the distal one smaller, while in the other wing the smaller distal drop is represented by two very small dots in a line transverse to the wing; five hyaline drops in third posterior cell, two bordering on posterior margin of wing, two approxi- mated to fifth-vein, and one bordering on the sixth (anal) vein considerably removed from the margin; four obscure hyaline drops in the less infuscated anal angle of the wing, inside the anal or sixth vein; the coloring becomes more or less dissolved toward the wing base, the second basal cell being mostly clouded on distal half. Third vein bristly to a point about opposite or a little beyond termination of second vein, first vein bristly nearly VOL. 1V. | A New Trypetid. 15 all of its length. ‘The markings of the wings are nearly black, or brownish black. Halteres pale tawny, knob pale lemon yellow. Length (with abdomen curved under), hardly 3 mm.; of wing, 314 mm. It is quite probable that a separate genus will have to be created for this form, at some future time, based on the shape of | the wings, the bristly third vein, and the four bristles of the scutellum. Nore on HEXACHATA AMABILIS Lw. A single specimen of this most handsomely marked trypetid was taken with the” preceding at Chacaltianguis, December 31, on foliage of plants in the edge of the woods. The species of the family Trypetidee are remarkable for their handsome markings, but this species, while possessing no other colors than black, dilute brown, and two shades of yellow, is one of the most beautifully marked species of this beautifully marked family. The markings of the wing in this specimen are of a deep shining black. Loew does not mention the hyaline drop in proximal end of distal cell, or leaves it to be implied when he likens the pattern to that of 77. exzmza. According to Macquart’s figure of the latter (Dipt. Exot. Sup. 4, pl. 27, fig. 3), and allowing for the modification in Loew’s text, I would not call the pattern of 17. amadilis at all similar to that of HY. eximia. Loew’s description of the wing pattern agrees perfectly in nearly every detail with the present specimen. He described only the $.
