M e t episte rnum broad in most species; pronotum eampanulate to 
quadrate, the basal angles acute, laminate, or obtuse, but not prolonged 
over the humeri; prosternum convex; forecoxal cavities usually narrowly 
open or closed behind. Genotype, (Leptura) sexgidtata Fab. 
Key to the Species 
A Pronotum with basal angles acute or subacute ( impura ) and laminate. 
B Pronotum feebly and gradually narrowed before the middle ( carbonata , 9, rather 
strongly narrowed), basal transverse impression narrow, sparsely punctured, 
and shining towards the middle and continuous across the dorsum; first two 
segments of hind tarsi with stiff setal brush; rather elongate species. 
C Disk of pronotum flattened, centre of disk with punctation nearly obsolete, 
smooth and shining; elytral apices truncate, feebly, narrowly emarginate. 
(1) carbonata, Lee. 
CC Disk of pronotum convex, roughly deeply punctured, closely in front on the 
median line, which is smooth and subcarinate behind; elytral apices broadly 
emarginate. 
D Pronotum not abruptly constricted at the apical margin, with the punc- 
tures smaller and closer on the median line in front, but coarser and 
much less closely placed on the sides of the disk; basal transverse 
impression gradually impressed; elytra with punctures coarse and sub- 
confluent on the basal half, small and close behind; antenna in the 
female very short, stout, and clavate. (2) brevicomis Lee. 
DD Pronotum abruptly constricted at the apical margin, with the punctures 
small and dense throughout, in some cases a little sparser midway 
between the sides and the middle line; basal transverse impression 
strongly, abruptly impressed; elytra with the punctures small and 
close on basal half, minute and dense behind. 
(3) nigrella Lee. 
BB Pronotum with sides inflated towards middle, then very strongly and abruptly 
narrowed to the apical margin, which is very much shorter than the basal mar- 
gin, basal transverse impression broad, densely punctured, and opaque; short, 
stout species. 
C Pronotum with the sides inflated and angulate before the middle; the basal 
transverse impression continuous across the dorsum (except knutli). 
D Elytra rounded or subtruncate at the tip. 
E Head at least nearly as wide as pronotum at the middle; the pronotum 
with anterior impression deep and wide.
