7 8 OKTHOPTERA. 



e-. Fastigium of the vertex less prominent, broadly and roundly 

 angulate, only about one-half as long as wide ; basal joints 

 of antennae scarcely depressed. [Interior tablelands of 

 Mexico.] , 16. viridescens, Scudd. 



Note. — Owing to the unsatisfactory descriptions of Oxycoryphus totonacus, Saussure, and Stenobothrus 

 decisu$, 8. viridissimus, and 8. mexicanus, Walker, all of which seem to belong to Orphulella, these forms 

 have been omitted from the foregoing table. Possibly 8. mexicanus is the same as Acridium jcmnctatum, 

 De Geer. If distinct, it will necessitate its being renamed, and the name of Orphulella walkeri is 

 suggested. S. decisus is found in Santo Domingo, and no doubt is a good species ; while 8. viridissimus 

 6eems to be nearly related to, or the same as, 0. meridionalis, which is described below.

[2. Orphulella graminea, sp. n. 



Pale grass-green, with a faint dusky line on the head, back of the eyes, and along the upper edge of the sides 

 of the pronotum, crossing over to the disc on the hind lobe, bordered above by a narrow line of dirty 

 white, the latter following the lateral carinae of the pronotum. The basal portion of the disc of the 

 tegmina showing traces of a median longitudinal row of light and dark spots, beyond the middle 

 transparent. Eyes ferruginous and sometimes likewise the antennae. Anterior and middle legs, 

 together with the hind femora and the body below, uniformly green, the latter much paler than the legs ; 

 the hind tibiae dull grey, the outer edge provided with ten spines. 



Head rather broader than the front edge of the pronotum, the occiput a little ascending and gently arched ; 

 the fastigium slightly acute ( 3 ), or meeting at, about a right angle in front ($), in the 3 advanced 

 beyond the eyes by nearly or quite half the length of the eyes as seen from above, rather decidedly 

 sulcate; lateral foveolae elongate-triangular, not very plain. Antennae with the joints scarcely depressed, 

 acuminate, about reaching the last transverse sulcus of the pronotum in the 5 , or a little beyond in 

 the 3 . Pronotum with its lateral carinae nearly parallel on the anterior lobe, divergent on the posterior 

 one, the two lobes almost equal in length, the front one a trifle the longer. Tegmina slightly surpassing 

 the tips of the hind femora in both sexes ; the latter rather long, extending a little beyond the apex of 

 the abdomen, even in the $ . 



Length of body, 3 17, $ 24-26 ; of pronotum, 6 3-3, 2 4-25 ; of tegmina, 3 14, $ 19 ; of hind femora, 

 3 11, 2 14 millim.
