3. Leptoftomum gracile, or (lender leptoftomum: leaves 
ovate-oblong, rather pointed; terminal hair half their 
length; capfule oblong, ftraight, drooping. Gathered by 
Mr. Archibald Menzies, at Duflcy bay in New Zealand. 
Stems denfely tufted, fomewhat branched, about an inch 
high, thickly clothed with rufty down in their lower part. 
Leaves yellowifh-green, dotted, clofe-prelfed when dry, 
pellucid, ltrongly revolute, with a very thick rib, and a 
l'mooth terminal hair. Fruit-ftalk near two inches high, 
(lender, tawny, with a (heath at the bottom, the fummit 
very (lender and drooping. 
4. Leptoftomum Menziefii. or Menzies’ leptoffomum : 
leaves oblong-lanceolate, acute; terminal hair a quarter 
their length ; capfule cylindrical, drooping recurved. 
Difcovered by Mr. Menzies at Statenland in 1787. Stems 
half an inch or more in height, moftly (imple, with denfe 
rufty fibres and roots. Fruit-italk about an inch high, 
(blitary, ereft. 
Mr. Brown with good reafon fufpefts that the Bryum 
macrocarp'um of Hedwig may belong to this genus. If 
lb, there is an error in the delineation of its fringe ; and 
it will prove the only known fpecies whofe leaves are tip¬ 
ped with a branched hair. Linn. Tranf. vol. x. p. 320.

LEPTU'RA, f [from the Gr. \eir lo«, (lender, and 
tail.] The Wood Beetle ; in entomology, a genus of 
coleopterous infects. Generic characters—Antenna; fe- 
taceous; palpi four, filiform; wing-cafes tapering towards 
the tip; thorax (lender and rounded. Thofe of the Lep- 
turte which have the lip entire, conftitute the genus Do- 
nacia of Fabricius; and fuch as have the lip bifid form a 
part of the Lepturae of that author ; for the latter do not 
exclufively confift of thofe infects which, according to 
the Linnaean character, belong toLeptura; Leptura ab- 
breviata of Fabricius, for example, is Necydalis major of 
Linnaeus, and Leptura variegata the Gmelinian Necy¬ 
dalis variegata. The Leptura tribe is allied to the Ce- 
rambyx, and contains 128 fpecies, fome of which are of 
confiderable beauty. The larvae of the wood-beetles are 
found, like thofe of the Cerambyx, in the perforated 
trunks of trees ; and, like them, they devour the pulve- 
rifed wood when digging their retreat.
