LEUCO'MA, among the Athenians, fignified a public 
reg liter of the whole city, in which were written the 
names of all the citizens, as foon as they came to be of 
age to enter upon their paternal inheritance. 
LEUCO'MA, f. [from Asvxo;, Gr. white.] Infurgery, a 
whitifh opacity of the cornea, fimilar to the albugo ; and 
requiring the fame mode of treatment. See the article 
Surgery. 
LEUCO'MA,/. [Greek.] A white fear in the horny 
coat of the eye. 
LEUCONO'TUS, / [Latin.] A dry fair fouth-welt 
■wind. 
LEUCOPE'TRA, in ancient geography, fo called from 
its white colour, a promontory of the Bruttii, in the ter¬ 
ritory of Rhegium, the termination of the Apennines ; 
the utmoft extremity of the Bruttii, or the modern Cala¬ 
bria Ultra ; as the Japygium is of the ancient Calabria, or 
the modern Calabria Citra. 
LEUCOPE'TRIANS, f in ecclefiaftical hiftory, the 
name of a fanatical febt which fprang up in the Greek and 
eaftern churches towards the clofe of the 12th century. 
The fanatics of this denomination profefled to believe in 
a double trinity, rejected wedlock, abftained from flefh,. 
treated with the utmoft contempt the facraments of bap- 
tifm and the Lord’s fupper, and all the various branches 
of external worfhip ; placed the effence of religion in in¬ 
ternal prayer alone ; and maintained, as it is laid, that an 
evil being, or genius, dwelt in the breaft of every mortal, 
and could be expelled from thence by no other method 
than by perpetual fupplication to the Supreme Being. 
The founder of this enthuiiaftical febt is faid to have 
been a perfon called Leucopetrus, and his chief difciple 
Tycbicus, who corrupted, by fanatical interpretations, 
leveral books of Scripture, and particularly St. Matthew’s 
Gofpel. 
LEUCOPHLEG'MACY, / Palenefs, with vifeid juices 
and cold fweatings.—Spirits produce debility, flatulency, 
fevers, leucophlegmacy, and dropiies. Arbuthnot on Aliments. 
LEUCOPHLEGM AT'IC, adj. [Asvxo$ and (pXtyfjLo., Gr.] 
Having fuch a conltitution of body where the blood is of 
a pale colour, vifeid, and cold, whereby it fluffs and 
bloats the habit, or raifes white tumours in the feet, legs, 
or any other.parts; and fuch are commonly afthmatic and 
dropfical.—Afthmatic perfons have voracious appetites, 
and for want of a right fanguification are leuccphlegmatic.

LEUCO'PHRA, /. in helminthology, the Transpa¬ 
rent Worm ; a genus of the order infuforia. This worm 
is invifible to the naked eye, and every-where ciliate. 
Species. 1. Leucophra conflidfor : fphterical, fubopake, 
■with moveable inteftines. Found in clear water; yel- 
lowifh with dark edges, and filled with moft minute mole¬ 
cules in perpetually-violent agitation. See Animalcule, 
vol. i. p. 723, 4. 
2. Leucophra veficulifera: ovate, with veficularinteftines; 
body pellucid with a dark edge, the middle frequently ap¬ 
pearing blue. See Hexminthology, Plate VI. fig. 21. 
vol. ix. p. 362. 
3. Leucophra acuta : black, pointed. 
4. Leucophra fluxa: finuate, kidney-fhaped. Body 
oblong, yellowifh, obtufe on one part, the other produced 
into a cone, and generally filled with molecules. This 
is fliown at fig. 10 on the Plate at p. 5.26. 
5. Leucophra armilla : round, annular. Body a little 
thickened above, and bent like a ring. See the fame 
Plate, fig. s1. 
6. Leucophra cornuta: inverfely conic, green, opake. 
Inhabits marfhy grounds. Body broad and truncate on 
the fore-part, with a fmall fpine each fide; the hind-part 
pellucid and pointed ; fometimes it appears oval or kid- 
ney-fiiaped, and, when the water which contains it eva¬ 
porates, it breaks into molecular veficles. 
7. Leucophra heteroqlita : cylindrical, obtufe on the 
LEG 
fore-part, the hind-part furnifhed with a double crefted 
ex fertile organ. Body to the naked eye like a white point; 
inteftines vilible. See Helminthology, Plate VI. fig. 22. 
8. Leucophra nodulata: ovate-oblong, deprefied,°with 
a double row of tubercles. Found in the inteftines of 
the Lumbricus terreftris and Nais littoralis; very pellucid, 
fliining like filver, and is propagated by a tranfverfe di- 
vifion; oval when young, and growing more oblong with 
age ; truncate at the tip. 
LEUCOPO'GON,/. [fo named by Mr."Brown, from 
the Gr. Aswco?, white, and irutyur, beard, on account of 
the white erect hairs on the upper fide of the legmer.ts of 
the corolla, very confpicuous even in dried fpecimens.] 
In botany, a genus of the clafs pentandria, order mono- 
gynia, natural order epacrideae, Brown. In the Prodromus 
of Mr. Brown, fo rich in botanical novelties, we find the 
definitions of forty-eight fpecies of this new genus, which 
he has feparated from the Styphelia of preceding writers; 
retaining in the latter fuch plants only as have four or 
more leaves to their external calyx; a more elongated and 
cylindrical corolla, with five internal tufts of hair near 
the bottom; the limb revolute as well as bearded; fila¬ 
ments prominent; and a rather dry drupe, always of five 
cells. It is, on the whole, a very elegant as well as natu¬ 
ral genus; and it is to be regretted that only one of the fpe¬ 
cies has hitherto been made known to our cultivators of 
curious plants. The plumy whitenefs of the flowers gives 
a ftriking and peculiar afpedt to the whole. See Epacus 
and Styphelia. 
LEUCOP'SIS, / in helminthology, the White-eye-; 
a genus of hymenopterous infefts. Generic characters 
Mouth horny, with fhort jaws ; the mandible thick, and 
three-toothed at the tip; lip longer than the jaw, mem¬ 
branaceous, and emarginate at the tip; feelers four, fhort, 
equal, filiform; antennae fhort, clavate; thorax with a 
long lanceolate fcale beneath ; wings folded; fting reflected, 
and concealed in a groove of the abdomen. There are 
four fpecies. 
1. Leucopfis gigas, the large leucopfis; black, with two. 
yellow dots on the back ; abdomen feffde, with four yel¬ 
low bands. Wings dufky ; hind thighs dentated. 
2. Leucopfis dorfigera, the high-backed leucopfis: ab¬ 
domen feflile, black, with two yellow bands and a dot be¬ 
tween them. Head black. Thorax gibbous, black, with 
a double tranfverfe yellow line; abdomen comprelfed and 
grooved on the back ; fting double, as long as the abdomen, 
and reflected back into the abdominal groove. Legs yellow, 
fpotted with black; hind-thighs toothed, with a black fpot. 
Upon the whole it appears at firft fight like a wafp, to which 
genus the folded wings would have referred it, had not 
the remarkable fting or tube on the back have prevented 
it. It is thought to be a fpecies between, and uniting, the 
fphex and wafp, in fome degree partaking of the charac¬ 
ters of both. The antennae are black and cylindrical, in- 
creafing in thicknefs towards the extremity ; the joint 
neareft the head is yellow; the head is black; fo alfo is the 
thorax, encompafted with a round yellow line, and fur¬ 
nifhed with a crofs one of the fame colour near the head. 
The fcutellum is yellow; the abdomen black, with two 
yellow bands, and a fpot of the fame colour on each fide 
between the bands. The anus and the whole body, when 
viewed with a low magnifier, appear punftuated ; and the 
points, when examined carefully, feein to be hexagonal, 
and in the centre of each hexagon a fmall hair is feen. In¬ 
habits Italy, Swiflerland, France, and fome parts of Ger¬ 
many. This beautiful infeCt is figured in Adame’s Eifays 
on the Microfcope ; the drawing was taken from a fpecimen 
in her majeffy’s cabinet of infers. There is one alfo in 
the cabinet of Linnaeus, now in the pofleffion of Dr. Smith, 
P. L, S. Our delineation is taken from Fuefsly’s Archives 
de i’Hift. des Infebtes: fig. 12 (hows the infebt of the na¬ 
tural fize; fig. 13, the fame lying on its back. 
3. Leucopfis petiolata : black; abdomen petiolate, fer¬ 
ruginous; the.petiole with a yellow dot each fide. The 
thorax is elevated, with two yellow ftreaks Before; under
