Pronotum with hind angles prolonged and acute, subcampanulate or 
trapezoidal; head constricted shortly behind the eyes; apices of elytra 
usually emarginate and bidentiform, elytra cuneiform; forecoxal cavities 
usually narrowly open behind; wings with closed cell in radial sector very 
elongate; of comparatively large size and elongate form. Genotype, 
(Leptura) quadrifasciata L. 
Key to the Species 
A Metepistemum with sides converging regularly from base to apex; antennae serrate; 
elytra rufous; very large species, length about 25 to 35 mm. 
B Prothorax densely punctured; elytra strongly suleate. (1) gigas Lee. 
BB Prothorax rather sparsely punctured; elytra at most only faintly suleate. 
(2) emarginata Fab. 
AA Metepistemum with sides subparallel on basal half; antennae filiform; smaller 
species, about 10 to 20 mm. in length. 
B Pronotum trapezoidal, sides converging feebly from base to apex; subangulate in 
front of middle, but little narrowed at apical margin; elytra red, black, or bi- 
coloured, length 18 to 19 mm. (3) anthracina Lee. 
BB Pronotum campanulate, the sides distinctly rounded and narrowed on the apical 
fifth. 
C Eiytral apices very strongly dehiscent. 
D Eiytral apices very strongly oblique and emarginate; pronotum with 
caudal transverse impression deeply excavated across the dorsum; 
front coxal cavities closed or narrowly open behind. 
E Pronotum nearly as wide as the elytra at the base; pubescence short 
and decumbent; stout species. (4) mdominalis Hald. 
EE Pronotum distinctly narrower at the base than the elytra; with pub- 
escence elongate and erect, finely punctured; slender species (c? only). 
(5) kemiana Fall. 
DD Eiytral apices subtransversely truncate; pronotum with the caudal trans- 
verse impression feeble, disk rather coarsely punctured, median line on 
the disk narrowly impressed; front coxal cavities rather widely open 
behind. (6) plagifera Lee. 
CC Eiytral apices at most only feebly dehiscent. 
D Pronotum with disk only moderately convex, with median line distinct; 
elytra finely closely punctured, apices obliquely trim cate-emarginate . 
E Pronotum with the caudal transverse impression feeble across the dor- 
sum, the median line distinctly impressed only toward the base, 
pronotum at the base much wider than the middle, punctures very 
fine and dense; elytra bicoloured, black and testaceous, the suture, 
lateral margin, apices, and a median transverse spot or band black. 
(7) subhamata Rand. 
EE Pronotum with the caudal transverse impression deeply excavated 
across the dorsum, the median line distinctly, usually rather broadly, 
impressed. 
F Elytra unicolorous; punctation of pronotum very fine, and feebly 
impressed, elytra black or testaceous with tips black; size small, 
slender. (8) plebeja Rand. 
FF Elytra maculate, punctation of pronotum of moderate size and 
deeply impressed. 
G Antennae black and very slender; prothorax black, body and legs 
slender , punctation of the eljrtra of moderate size and only 
moderately close, with two lateral spots and apices black.
