242 ORTHOPTEKA. 



No specimens of the present species are at hand, It probably reaches the southern 

 portions of Central America. 



PRIONACRIS, Stfil. 



Prionacris, Stal, Syst. Acrid, i. pp. 19, 55 (1878) ; Pict. et Sauss. Cat. Acridiens, i. p. 35 (1887). 



This is still another genus of the large, lobe-crested locusts of Tropical America 

 that should be included in a treatise of the Orthopterous insects belonging to Central 

 America. Only a single species is known.

Hab. South Ameeica, Colombia 1 3 . 



Neither specimens nor records are at hand to indicate the presence of P. compressa 

 in Central America, yet, in my judgment, it should be included in the locust-fauna 

 of that country,

 Gundlach, Ent. Cuba, ii. pp. 343, 344 (1890). 



This genus seems to be confined to the island of Cuba ; nevertheless it requires 

 notice here.

The various species of Nautia are of moderate size and olive-green in colour, with 

 the face, occiput, pronotum, and tegmina variously lined or marked with yellow and 

 brown. They live among the herbage and small shrubs growing in openings or 

 clearings at the margins of the forests of Tropical America, and are either rare or else 

 sufficiently active and alert to keep out of the collector's reach. The following brief 

 table will aid in separating the species so far as known to the writer.
