The large female nymph is dark optuiue brown in coloi-. liuliirr 

 below. Head armed as in th«' adult as are also the pro- and nicsonutuni. 

 though the spines or tul)er('les are here quite small. Anterior legs 

 unarmed, though the foi-e tibia' of the small male specimen have a 

 small com pressed expansion near each endabove, ashavealsoall the tibia' 

 in that specimen. In the larg(> female nymph these expansion.- are 

 mantained only on the middle pair where there is. in both nymjjhs, 

 also a small longitudinal ex})ansion neai- the base l>elo\\ . Middh' and 

 posterior femora furnished above with a pair of ])arallel lobes near the 

 apex and armed Ixdow with spines as in the 

 adult, except smaller. The measurements 

 are as follows:

The right hind leg of this specimen has been bi-oken oti and regenei"-

 but 9 mm. in length. 



This species was described from Santo Domingo, West Indies, and is 

 an unusually interesting addition to our fauna by reason of it-^ being 

 the only winged I'epresentative of the family occurring witiiin our 

 borders. The long-winged males are objects of note and suggest 

 tropical forms. The asymmetrical horn-like tubercles of the head 

 .seem to be a constant character of the geinis. Why one <)f these 

 tubercles, usually the one on the right, should 1)<> longer or larger than 

 its fellow is, so far as I know, unexplained.

A pair of this Mexican sj)ecies was taken atCialveston. Texas, by Mr. 

 Schaetier. No date is given. It exhil)its certain characters .somewhat 

 at variance with those of typical specimens taken in Mexico. At first 

 I thought it represented a new species, but Prof. Laurence Ibuner. who 

 is writing that i)artof the Biologia Centrali-Americana treating of the 

 Acridiida^ and is well informed on the fauna of that region, thinks it is 

 a variety of sniiiichroxt!. The following description is made from these 

 specimens (tig. 3), which may be designated by the varietal name .^uh-
