teeth or tubercles at the elevated and posterior part of the 

 truncation ; cases smooth. It lives as well in the perfect as in 

 the larva state, in tan-beds. 



There is found in the South of Europe another species, 

 G. silenus, (Fab. Oliv. Col. I. 3, 8, 62, a — c) smaller than 

 the last, of a brighter marron broAvn ; a little bent and 

 pointed horn on the head of the male ; a deep excavation in 

 the middle of the corslet, the last articulation of the two an- 

 terior tarsi swollen, with two very unequal hooks. The elytra 

 are fine, and vaguely dotted.* 



Agacephala, Manh., 



Whose fore feet, in the males at least, are longer than the 

 others, and whose four hind legs are slender, or but little 

 thick, cylindrical, and slightly dilated at their extremity, 

 without notches or deep lateral incisions. 



The labrum is entirely hidden. The lobe terminating the 

 jaws is simply downy. The antennae have ten articulations, 

 and it is an error in the Encyclop. Method. (Art. Scarabasus) 

 to say they have only nine. 



I know two species both from Brazil. G. CEgeon of Fab. 

 is probably congenerous with them. 



Sometimes the jaws, commonly corneous or scaly, are more 

 or less toothed. 



* Add Geotrupes boas, rhinoceros, stentor, &c. of Fabricius. 



G. orphnus, of Mr. Macleay, established on G. bicolor, of Fab,, does 

 not differ from the last. The anterior edge of the labrum is salient, or 

 exposed. The jaws are terminated by a bundle of spinuliform lashes, 

 arched outwardly, with a crustaceous triangular lobe. The knob of the 

 antennae is almost globular. His genus, Dasygnathus, which he places in -si^ 

 the family of Dynastides, is unknown to us j but we suspect, from the 

 exposition of its characters, that it approximates to the last and the fol- 

 lowing. The jaws are not toothed.
