Hah. Cuba {Scudder, Bolivar, Brunner). 



While the West-Indian Islands are not exactly a part of the country embraced by 

 this work, in the present and several other instances certain insects are introduced on 

 account of their close relationship to Central-American forms, or else because of their 

 special interest to the student in his investigations along faunal lines.

Hab. Colombia [Serville). 



The description of M. mutilata is so incomplete that it is difficult to compare 

 the insect with others without having specimens at hand for the purpose. Even 

 Mr. Malcolm Burr does not seem to have decided definitely anything about it, since 

 he has left M. mutilata out of his table for separating the species of the genus, although 

 on p. 8 of his * Essai ' he has referred it to Masyntes.] 



[MORSEA, Scudder. 

 Morsea, Scudder, Psyche, viii. p. 179 (1898) ; Burr, Essai sur les Eumastacides, p. 63 (1899). 



Morsea, as indicated by the above table for the separation of the genera, approaches 

 most closely to Masyntes, which is found in Cuba and over a considerable portion of 

 Tropical South America. It differs from that genus, however, in having shorter legs, 

 and in the spines of the inner side of the hind tibiae being equal, instead of alternately 

 long and short. From Episactus, Brunner, which also has the sulcus of the vertex 

 separated from that of the frontal costa by a transverse ridge, it may be known by the 

 basal joint of the hind tarsi being smooth above, instead of toothed. Thus far, but a 

 single species has been recorded.
