an acute tubercle; between which, in the place of the in- 
termediate horn, there is an elevated transverse line or 
ridge. This sex differs from the female of Sc. Typhceus in 
scarcely any thing but size. 
What may be the use of the horns which arm the thorax 
of the male of Sc. Typhceus and pumilus, and the head and 
thorax of many of the same sex in the Fabrician genera 
Copris and Geotrvpes, seems at present not ascertained : if, 
however, the insect before us be taken in the hand and 
held fast, he will resist incumbent pressure with great force, 
and make way under it ; from which we may conjecture 
that these horns are useful to him in excavating his sub- 
terraneous habitation. 
Our drawing was made from specimens in the cabinet of 
the Rev. W. Kirby. The upper figure represents the male , 
and the lower the female.
