approximation to the latter in several species of 

 Strategus, which are armed with a short horn or 

 tooth on the anterior part of the thorax, as well as 

 with lateral tubercles. Both sexes have the front 

 of the forehead bituberculate. There are several 

 species belonging to this genus, viz. Sc. Semiramis 

 of Palisot Beauvois, and probably also Sc. 4-fove- 

 atus and oblongus of the same author. Sc. Recti- 

 cornis Kirby, may be added, as well as Geot. An- 

 taeus Fab. Geot. iEnobarbus, Syphax and Titanus 

 of Fabricius, Massinissa of Kirby, and Ajax of 

 Olivier, belong to the same genus ; they have the 

 intermediate thoracic horn furcate and deeply emar- 

 ginate at the apex. In two remarkable insects in 

 my collection, which I have named Montesuma and 

 Pizarro, closely approaching Strategus, the lateral 

 horns are furcate, the intermediate one is nearly 

 evanescent, it is probable that the former belongs 

 to a subgenus as the mouth is different, and the 

 anterior tarsi quite anomalous. 



Genus. Celosis, Kirby. 

 Type of the Genus. Geotrupes Sylvanus, Fab. 



Caput triangulare, cornu recurvo clypeo emar- 

 ginato.
