head by a well-marked transverse carina, before the neck 
there is a second transverse carina, equal in length to the 
first, punctures between the carine not confluent nor so large 
and deep as those in the clypeus; the thorax convex on the 
disk, evenly, not coarsely punctured throughout, punctures 
obsoletely ocellate, at the side near the middle of the lateral 
edge is a small ill-defined boss ; the elytra dull brown, striz 
somewhat faint, interstices flat, with two rows of granules ; 
the pygidium punctate, punctures frequently confluent; the 
legs and antenne obscurely brown, tibie tridentate, the apical 
tooth is at right angles to the tibia, leaving the end truncate. 
The species is about the size of O. brevis, Waterh.; the 
thorax is more convex than any other of this series. I believe 
my example’is a male.

Onthophagus ocellato-punctatus, Waterh. /. c. p. 79 (1875). 
The male has a slender and somewhat straight horn on 
the posterior edge of the head; this sex was unknown to 
Waterhouse. 
Hab. Hiogo in August 1871, and on the sand-hills at 
Hakodate in September 1880. 
Note.—Caccobius is a generic name proposed for such 
species of Onthophagus in which the tarsal end of the tibia is 
truncate; but intermediate forms occur between Caccobius 
and the typical Onthophag?, and the genus is now considered 
to be of doubtful validity.

Waterhouse thought that Motschulsky’s words “ angulis 
posticis subacutis ” did not apply to his Aphodius diversus ; 
but the few words of description he gives of C. rectus apply 
in other respects, and some latitude of interpretation is neces- 
sary with this author. I also consider that the C. vitta, 
Motsch., is the common colour-variety of A. Solsky?, Har., 
very abundant in Japan. ‘There is nothing except the words 
“tenue punctato-striatis’’ as apphed to the elytra, against 
the ‘ punctato-striatis ”’ applied to C. rectus, that can throw
