It would seem that this insect is rather widely distributed in the lower regions at 

 least of Tropical America. Six examples have been seen by me.

Although this genus does not appear to be represented in the various collections 

 examined, it is mentioned as one that is likely to occur in the region under investi- 

 gation. Only a single species has thus far been described.

The locusts which are included in the genus Dichromorpha do not appear to be very 

 numerous in species, since but four are known to the present writer. Two of these 

 are normally long-winged and are described as new ; they come from the same locality 

 on the west coast of Mexico. The others are normally short- winged and are remarkably 

 wide-spread : one of them, D. viridis, Scudd., ranges northward from Vera Cruz to 

 Southern Canada ; and the other, D. australis, Bruner, is said to occur in Brazil, 

 Paraguay, and the Argentine Republic as far south as Northern Patagonia. Both of 

 these latter sometimes occur as long-winged individuals, but, as stated above, are 

 normally brachypterous. They are also represented by two colour- varieties, viz. green 

 and testaceous, and in the latter are very frequently thickly marked with dark brown
