 Stal adds G. rupicajpra, Fabr. 



Head fuscous, eyes castaneous, a white spot before the eyes : thorax 

 fuscous with two stout horns, a little arched, produced posteriorly, fili- 

 form : sides of pectus white : wrings obscure : body fuscous {M. taurus, 

 Fabr.). Body small, fuscous; thorax with three horns, the lateral 

 thicker, obtuse or rather truncate, subdentate ; the intermediate, poste- 

 rior, recurved : tegmina fuscous hyaline ; wings whitish (M. rupicapra, 

 Fabr.). Fairmaire remarks that G. taurus is black with the scutellum 

 and sides of the pectus white and the tegmina with the costa fuscous. 

 Hardwicke describes his M. tricornis as head, thorax, and body black ;
