58 ORTHOPTEBA. 



The specimen ( e ) described by H. Dohrn has the abdominal segments rufous, with 

 black margins, and the legs rufous, with the anterior femora armed with only one spine 

 — placed on the inner (anterior) margin. Nevertheless I believe our individual from 

 Guatemala belongs to the same species, the proportions being similar. 



M. (Bldbera) regina, Sauss. (from Brazil ?), may be inseparable from M. rufipes, 

 Dohrn, to judge by its size. 



M. peruviana, Dohrn (= Blab era rujipennis, Walk.), from the Upper Amazons, seems 

 to be a smaller species, with more spined anterior femora, although this character is 

 somewhat variable.
