the costa, instead of parallel to the radial vein. In his synopsis 

 (/. c. pp. 22-29) he lists seventy-eight species. I am now adding 

 three others. It is quite certain that a number of still undiscovered 

 species will be found to inhabit the various parts of tropical America 

 as they become better explored. 



Many of these insects are quite similar in their general appearance 

 and differ chiefly in the form and length of the fastigium as well as 

 the color of the vertex, length of the wings, hind femora, in spine- 

 characters and in the comparative smoothness or granulation of the 

 pronotum, etc. The form and length of the ovipositor is also a diag- 

 nostic character. Most of the species live among grasses and other 

 low herbage, but also frequently are to be met with among the foliage 

 of trees. They are readily attracted to bright lights, and may be col- 

 lected at night in cities and towns.

There is an almost grown female nymph at hand which is referred
