region), with numerous dull shallow punctiform impressions placed 
very irregularly. Femora and tibiae fringed with black hair. Sternum 
smooth and shining, with a well-marked broad impression between 
the intermediate legs. 
Length 22 millim. 
This species most nearly resembles the Indian Scarabceus sandus, 
Fabr. The sides of the thorax are, however, more regularly rounded, 
much less sinuate before the posterior angles; the shining discoidal 
line is broader, and there are no smooth spots on each side of this line. 
The elytra have the striae finer and neater, the interstices are flatter, 
coriaceous, with the punctiform impressions smaller and more separated 
from each other. 
Onthophagus Johnstoni, n. sp. 
Entirely black, except the apex of the antennae, which is rusty- 
yellow. Head as long as broad, obliquely narrowed in front of the 
middle, rounded at the apex, closely and coarsely rugose, except near 
the eyes. There is a slightly raised straight ridge between the 
eyes, and a second, longer one halfway between this and the 
front of the clypeus. The thorax is smooth, shining at the sides 
and in front, slightly dull above; the fore part is perpendicularly 
truncate ; the truncature bounded above by a slightly prominent ridge ; 
viewed from the front there are three shallow impressions : on each 
side there is a line of small tubercles bounding the discoidal area; the 
surface of the disk is moderately closely but extremely delicately 
punctured, and appears impunctate to the naked eye; the sides are 
more distinctly punctured: the base is oblique on each side, and is 
angularly produced in the middle. The elytra are convex, shining, 
not quite twice as wide as the length at the suture, rounded at the 
sides and apex, very delicately striated, the strise delicately punctured ; 
the interstices flat, sparingly punctured ; near the suture the punctures 
are extremely delicate but become more distinct towards the sides. 
The pygidium is rather sparingly but distinctly punctured. The sides 
of the sterna, the margins of the femora, and the posterior tibiae are 
fringed with long black hair. 
Length 21-25 millim. 
I know of no species which much resembles this. Its most near 
ally is a species which I have seen named 0. nodis , Th., in Mr. Bates’s 
collection. The species has somewhat the general build of 0. marsyas , 
01.; the head is longer, the clypeus not sinuous at the sides ; the 
thorax rather flatter above, with a prominent, nearly straight ridge in 
front above the anterior perpendicular truncature; the anterior angles 
are as if truncated ; the base is more angularly produced in the middle 
of the base ; the elytra are scarcely narrowed at the base, &c.
