a new subfamily of Scolytide. 433 
convex, impressed over mouth, front slightly flattened, with a fine 
median impressed line, and somewhat close punctuation, mouth 
fringed with hair, and front with short dense pubescence. Antenne 
with scape and funiculus nearly similar in both sexes, the former 
more strongly clubbed at apex in male; club in male acuminate, 
with a fringe of about 14 long serrate cilia on inner side and apex, 
in female exactly oval, shortly hairy. Prothorax rather broader than 
long, more distinctly so in the male which has the anterior border 
emarginate, its base feebly bisinuate, basal angles nearly rect- 
angular, sides subsinuate to near apex, with anterior angle of 
emargination inconspicuous, thence strongly rounded; its surface 
variable in colour, entirely ferruginous, or with an anterior black 
patch, which may invade the whole dorsum, finely reticulate with 
short sparse pubescence and a fine median raised line, limited in 
front in the females by dorsal pore, distinctly punctured in male, 
the punctures close on anterior third at sides of median line, in 
female with finer sparse punctuation. Elytra wider than thorax 
at base, and twice as long, basal angles rectangular, rounded, 
sides feebly convex to near apex, then strongly rounded at apical 
flexure, apex obtusely rounded; surface convex, slightly flattened 
in middle, somewhat shining, ferruginous, or with sides and 
suture blackish, or entirely black, irregularly punctured with fine 
striate impressions, the punctures of which are barely distinguish- 
able from those of the interstices ; in the male the strie are deeper, 
especially the sutural stria, and the interstices are feebly convex ; 
apical declivity rounded, shortly pubescent, striate, its interstices 
subconvex, with close rugose punctures, 1st with seven or eight, 
8rd with five or six small tubercles, the other segments with 
traces of tuberculation at the base of the declivity. Tarsal joints 
2—8 strongly dilated. Under side punctured and hairy; abdominal 
segments 1 and 2 longer than 3 and 4. Lateral fovea of thorax 
indistinct in male. 
The male prosternum does not show the remarkable 
modification of its anterior edge seen in the next two 
species, and in S. mikado.
