Geodephagous Coleoptera of Japan. 301 
produced ; the liind margin is cut obliquely on each side ; 
the surface is finely rugulose, shining on the disk but 
opake on the hind borders ; the basal fovea is distant from 
the angles, short and oblique. The elytra are much nar- 
rower than in B. impressum, and much more strongly 
striated; the interstices are more finely sculptured. 
B. conicicolle (Motschulsky), from Eastern Siberia, 
appears to be closely allied to the present species ; but 
the hind angles of thorax are described as rectangular, 
and the margin straight.

Nagasaki. Also China. 
I do not detect any difference of importance between 
Egyptian specimens and others from the Yang-tsze-Kiang. 
Mr. LcAvis's collection contains a small individual fi^-om 
Nagasaki. The elongation and convergence on the epi- 
stome of the firontal grooves distinguishes the species.

Nagasaki. 
Closely allied to the European B. Bruxellense, differing 
almost solely in the rather longer and less rounded thorax, 
with less sinuated sides.

Hiogo ; Nagasaki. 
I am imable to discover any specific difference between 
Japanese examples and others taken in England.

Kobe ; on the beach. 
Allied to B. tihiale. Body similarly depressed. The 
frontal furrows are broad, leaving a rather narrow convex 
space down the middle. The thorax is cyathiform, i. e., 
very much rounded on the sides (with deflexed anterior 
angles), and strongly narrowed or constricted near the 
base; the hind angles are rectangular, the base rugose-
