marked but apparently complete; thorax, similarly punctulate, 
stria fine behind the head, strong at the sides, little sinuous and 
leaving a moderately wide margin; the elytra, striæ 1-3 com- 
plete, 4-5 apical, reaching the middle, 5 being slightly longer 
than 4; the propygidium impressed on either side and with the 
pygidium evenly and densely punctate throughout; the proster-

ate, anterior lobe somewhat densely punctured ; the mesosternum 
emarginate, stria complete (in one specimen a little interrupted)

in being almost identical with those of 2. Confucii Mars., but the 
other characters are wholly different.
