1 differ eutireh' fi'oui Dr. Stal iu the synouymy wliich he 

 gives to the species of this genus. In his sectional, or ])erhaps 

 specific diagnoses, he gives the height of the thoracic processes, 

 their width and angulation at the apex, and the depth of the 

 sinus between them, as distinctive characters : so far so good — 

 but M. sinuata and the type or E. impedita agree not only in 

 these very characters but in coloration, whilst E. bactrina differs 

 chiefly in the stronger angulation and expansion of the anterior 

 process (at least in our example), E. concisa in the greater 

 length and almost falcated inner edge of the anterior process, 

 E. decisa in the falcated opposed inner edges of both jirocesses 

 and its black coloration, E. avcisa in its shorter processes and 

 consequently much shallower sinus and its blackish and yellow 

 coloration, E. indecisa in similar structural characters to the 

 last and its brown and yellow coloration, E. reducta in its still 

 shorter processes and shallower sinus. I should have no objec- 

 tion to considering the whole of the above mentioned forms as 

 varieties of one inconstant sjjccies ; but if we are to admit two, 

 we must of necessity accej)t several others.
