PHAULOTETTIX COMPRESSUS, new species. 

 (Plate II, fig. 11.) 



Brownish testaceous above, olivaceo-testaceous below, marked on the 

 sides with a feebly arcuate piceous stripe. Head dark brownish testa- 

 ceous above, with a piceous band behind the eyes, below which the pos- 

 terior parts of the genae are ferruginous, while the face and rest of the 

 head are olivaceo-testaceous; frontal costa punctate above; fastigium 

 very narrowly and slightly sulcate; antennae flavescent, growing fus- 

 cous apically. Pronptum dull olivaceo-testaceous on disk, with a large 

 median, fusco-ferrugiuous, trapezoidal patch, the upper half of the lat- 

 eral lobes blackish, the lower flavo-testaceous, excepting the dark lower 

 part of the front half of the prozona; sides of the abdomen with a 

 diminishing piceous band, broken by the pink incisures, the middle of 

 the dorsum becoming gradually brownish testaceous. Tegmina testa- 

 ceous. Fore and middle legs and hind femora green, the latter fusco- 

 luteous above, blackish on the sides of the geniculation, and luteous 

 within; hind tibiae red with a green base, the spines pallid, black- 

 tipped. Supraanal plate long triangular, well rounded at apex, strongly 

 tectate, with a moderately deep basal median sulcus, less than half as 

 long as the plate; furcula consisting of a pair of minute, attingent, 

 parallel fingers, hardly longer than broad; cerci slender, compressed, 

 short, tapering on the basal half, beyond equal, the lower outer extremity 

 acutangulate (hardly so represented in the figure). 



Length of body, male, 15 mm.; antennae, 6.1 mm.; hind femora, 8.6 

 mm. 



One male. Montelovez, Cohahuila. Mexico, September 20, E. Palmer. 



8. CEPHALOTETTIX, new genus. 

 (Kegxxfa), head; rsrri^, grasshopper.) 



Body subcylindrical with subparallel sides, slightly constricted in the 

 middle of the abdomen. Head large, prominent, well exserted, together 

 with the eyes considerably broader (at least in the male) than any part 

 of the thorax; vertex well arched, elevated above the pronotuin, the 

 fastigium rapidly descending, and the face considerably retreating, these 

 two at right angles; eyes very large and very prominent (in the male), 

 very broadly ovate, and yet nearly twice as long as the intraocular por- 

 tion of the genae; fastigium broadening considerably in front of the 

 eyes, sulcate throughout, the frontal costa considerably broader than 

 the interval between the eyes, yet not very broad, equal except for a 

 slight contraction above, feebly depressed just above the ocellus ; anten- 

 nae slender, about half as long as the body. Pronotum parallel sided, 

 scarcely widening at the metazona, the front and hind margin as in 

 Ehabdotettix, compressed cylindrical, with neither median nor lateral 

 carinae, the disk passing insensibly into the lateral lobes; prozona 

 sparsely punctate, about twice as loug as the densely punctate meta-
