Hal. Mexico, Cuernavaca in Morelos and also in Guerrero (0. W. Barrett) ; 

 Nicaragua (Shimek) ; Costa Rica (Bruner, Biolley).

 Hal. Mexico, Oaxaca 1 2 . 



While no specimens of this particular locust occur in the material before me, I have 

 no doubt but that it belongs to the present genus. It seems to be nearly related to 

 P. viatorius. 



4. Plectrotettix excelsus, sp. n. 



A medium-sized, rather robust species, with the light parts prevailingly green, and the anterior lobe of the 

 pronotum but little more than one-half the length of the hind lobe. The dark patch on the side of the 

 pronotum not arcuate and confined •wholly to the anterior lobe. The tegmina, in the two specimens 

 before me, on the dorsal edges are uniformly cinereous, except near the base, where they are tinged with 

 green. Hind femora with the dusky bands crossing the disc of the outer face and upper edge. Tegmina 

 and wings only a trifle surpassing the tips of the hind femora ; the latter with the lower sulcus and the 

 inner face in great part bluish ; the tibiae testaceous basally, becoming blue-tinted apically, 13-spined in 

 the outer row. 



Length of body, § , 33-35 ; of pronotum 6, of tegmina 29-30, of hind femora 21 millim. 



Hal. Mexico, Tlalpam and Tacubaya (0. W. Barrett, in coll. L. Bruner). 

 Two females. 



5. Plectrotettix macneilli, sp. n. (Tab. I. figg. 12, 12 a, b.) 



Slightly smaller than P. viatorius, and at once recognizable by its testaceous and black colouring, as shown on 

 the Plate. The other differences are set forth in the synoptical table for the separation of the species. 



Length of body, S 24, $ 33 ; of pronotum, J 4-5, $ 6 ; of tegmina, d 23-24, $ 30 ; of hind femora, 

 <? 17-5, $ 22 millim. 



Hal. Mexico, Orizaba (H. H. Smith & Godman; L. Bruner). 

 Numerous examples.
