the Lamellicorn Coleoptera of Japan. 385 
verso; thorace grosse punctato, utringue foveolato; elytris 
punctato-striatis ; pedibus piceis. 
L. 4} mill. 
Elongate, oblong, black, shining; the head transverse, 
anterior outline broadly arched, not emarginate, edge narrowly 
reflexed ; the thorax also transverse, with large punctures 
evenly distributed but not closely set and a fovea on each side 
well within the margin; the elytra deeply punctate-striate, 
interstices rather wide, convex, and smooth ; the antenna and 
mouth-organs reddish brown; the legs piceous, tarsi rather 
paler. 
In general outline and size this species resembles P. japo- 
nicus, Har., but it is not opaque; the head more transverse 
and not emarginate and the thorax is without any lateral 
impression. 
Hab. Nikko. One example from the bed of the river. 
Aigtalia nitida, Waterhouse. 
ZEgialia nitida, Waterh. Ll. c. p. 95. 
This species measures 34-4 miil., not 4 lines. 
flab. Hakodate, on the sand-hills. Four examples in 
September 1880. 
Ochodeus maculatus, Waterhouse. 
Ochodeus maculatus, Waterh. 1. c. p. 95, pl. 3. fig. 1. 
Hab. Kiushiu and on the main island. ‘This species 
originally came from Simabara and Tagami close to Nagasaki. 
In May 1882 I caught two flying at dusk above Mogi also 
close to Nagasaki. Mr. Pryer found one on Oyama near 
Yokohama. In the British Museum there is a similar species 
from Java. 
Bolboceras nigro-plagiatum, Waterhouse. 
Bolboceras nigro-plagiatum, Waterh. 1. c. p. 96, 2. 
The male of this species was not noticed by Waterhouse. 
On the head there is a somewhat stout and rugose horn, 
slightly emarginate at the apex ; the thorax has a transverse 
ridge behind the neck, and on each side of it is a tubercle 
similar to those of Copris lunaris, L., or C. pecuarius, Lew. 
There is a specimen in the British Museum from Korea which 
is either a variety of this species or one very similar to it, the 
sculpture of the head and thorax is different and the dark 
coloration of the elytra extends to the middle of each wing- 
case. 
Hab. Tokio, Yokohama, and Kobé. Not very common.
