^^■hore m the female. Vertex in front of the eyes ampliated and 

 roundly depressed, the sulcation wide and with its lateral walls 

 broadly angulate. Frontal costa broadest and most prominent between 

 the antennae, a very little narrowed above, broadly sulcate in the 

 vicinity of the ocellus at least, and coarsely punctate above. Antennte 

 normal. Pronotum C3'lindrical, a very little compressed in middle, 

 the transverse sulci all equall}^ plain, the last plainly behind the mid- 

 dle; anterior lobe g-labrous at sides, somewhat trans verseh' ru«>-ose 

 above, hind lobe coarsely and closel}^ punctate. Tegmina complete, 

 sparsely veined, a ver}^ little surpassing the apex of abdomen. Hind 

 femora moderateh^ robust, about the same length as the abdomen in 

 the two sexes. Space between the mesosternal lobes longer than wide, 

 narrower than the lobes themselves. Prosternal spine acute. 



The four species of ' Leiotettix before me as I write all agree in 

 having the dark bands back of eyes and along the sides of pronotum 

 green or greenish instead of piceous or fuscous. These species may 

 be separated by the annexed synoptic table: 



The species luridis ma}^ be considered as the type of the genus.

LEIOTETTIX VIRIDIS, new species. 



A medium-sized, grass-green, locust that at lirst sight reminds one 

 of a small Atraehelacris unic6loi\ Giglio-Tos, but which upon a little 

 closer examination is readily observed to be quite distinct. 



Head rather large, fully as wide (female) or even a little wider (male) 

 than the front edge of the pronotum; the eyes fairly prominent, fully 

 as far apart above as the width of the frontal costa between the base 

 of the antennfe; fastigium of the vertex roundly depressed, the lateral 

 carinas broadl}^ angulate, in some specimens meeting in front and sepa- 

 rating the sulcation of this part from that of the costa by a faint ridge; 

 frontal costa quite broad, widest above the ocellus and between the 

 antenna;, sulcate, fading awaj" below before reaching the clypeus. 

 Facial carinte but little divergent below, fairly prominent. Pronotum 

 glabrous, short, subcylindrical, a little contracted in the middle, nearly
