an acute tubercle; between which, in the place ot" the in- 

 termediate horn, there is an elevated transverse line op 

 ridge. This sex differs from the female of Sc, Typ/iceus 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 Geotnipes, 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, 

 anfl make way iinder it ; from vi'hich 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 or 

 the Rev. W. Kirby. The upper fgure represents the jnale. 

 and tJie loicer iht female.
