Kiu-Kiang, on the Yang-tsze-Kiang. 
Similar to Chi. inops, but at once distinguished by its 
longer thorax, Avhich is pretty regularly and not strongly 
I'ounded from the base to the apex, the hind angles being 
obtuse, the widest part at the middle, and the anterior 
part much narrower than the base ; the yellow margin is 
narrow and uniform ; the surface differs from that of Clil. 
inups and vestitus, in being finely roughened throughout, 
and covered besides with short, transverse strigtB, the oi"di- 
nary punctuation being similar in all three species. The 
head is finely punctured, and more or less strigose over its 
Avhole surface. The elytra are more elongate and parallel- 
sided, less oval, than in the two species cited ; densely 
pubescent, finely but sharply punctulate-striated, the inter- 
stices plane and minutely punctulate ; the pale border 
occupies two interstices near the base, is narrowed in the 
middle, and widened again towards the apex ; it docs not, 
however, form a broad apical ]mtcli, and is there strongly 
denticulated. The underside is reddish-piceous, ])aler on 
sides of abdomen, punctulate and pubescent throughout.

Distinguished from Chi. sinensis by the narrow pale 
apical margin of elytra, instead of an apical spot, and also 
by the convex interstices.
