striatis, interstitiis subtiliter alutaceis; pygidio sat dense punc- 
tato, in medio linea longitudinali levi subelevata. 
Long. 20-23 mm. 
“This species is closely allied to Copris lunaris, L., but 
besides the size, it has several well-marked characters to 
distinguish it. The horn in the male is one third longer and 
without any notch at the base ; the thorax has the elevations 
more decidedly separated and formed as in acutidens, Motsch., 
but less acute. In both sexes the sculpture of the elytral 
interstices gives an appearance of opacity; the pygidium is 
somewhat closely punctured, and down the centre of it is a 
smooth well-defined line, which is slightly elevated.” 
Hab. Nikko, very abundant; also at several places on the 
Nakasendo. 
Onthophagus nikkoensis, sp. 0.

L. 53-6 mill. 
Oblong-ovate, brassy black, rather opaque; the head, 
clypeus anterior edge incised in the middle, surface strongly 
ai closely punctate, punctures transversely confluent, the 
suture is indicated by an evenly arched carina, behind the 
carina the forehead is densely ocellate-punctate, punctures not 
confluent, in front of the ee a second transverse carina; the 
thorax densely and clearly ocellate-punctate, in ? there is a 
gibbose elevation behind the middle of the head, in ¢ the 
gibbosity is more transverse and divided into three parts ; 
the elytra distinctly but not deeply striate, interstices opaque, 
with two longitudinal rows of small granules, rows most 
regular on the interstices near the suture, interstices usually 
reddish at the apices and bases; the pygidium clearly ocellate- 
punctate; the legs and antenne pitchy brown, the ends of 
the anterior tibiz are truncate like those of O. jessoensis and 
brevis. 
Hab. Nikko and Nara. Abundant at Nikko in June.
