278 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERa) 



to 9000 feet. The species was found not uncommon and rather 

 sluggish, most frequently along open parts of a trail, among 

 sparse growth of grasses on dry, sandy soil. 

 Bradjmotes deplanata new species (Plate XXIX, fig. 13 ; plate XXX, fig. 2.) 



This species is closely allied to B. pinguis Scudder (see plate 

 XXX, fig. 1), differing in the smaller size, broader form, deplanate 

 disk of pronotum with lateral carinae decided and, in the male 

 sex, in the slightly more slender cerci. 



The insect agrees with B. compacia Morse in the well-developed 

 lateral carinae of the pronotum. The pronotum differs in having 

 the disk deplanate and broader caudad, due to the fact that the 

 lateral carinae are strongly divergent caudad between the first 

 and second transverse sulci, thence rather strongly divergent 

 caudad, not almost evenly and weakly divergent caudad as in 

 compacta. In the male sex the cerci are not as slender as in B. 

 ohesa (Thomas) (see plate XXIX, fig. 10), compacta or B. kaibab 

 here described, of the same type but more slender than in 

 pinguis. 



Type. — cf ; Big Meadows of the Deschutes River, eighteen 

 miles southwest of Bend, Crook County, Oregon. July, 1913.. 

 (C. H. Kennedy.) [Hebard Collection, Type no. 502.] 



Size medium small for genus, slightly larger than in kaibab; form very heavy, 

 heavier than in that species or in pinguis; surface moderately pilose. Head 

 and eyes much as described for kaibab, except that the frontal costa is sUghtly 

 less pinched at its juncture with the fastigium and is scantily punctate. Pro- 

 notum with disk strikingly deplanate, expanding rather strongly caudad, this 

 greatest between the first and second transverse sulci, with lateral carinae well 

 developed as in compacta and continued to near the caudal margin; medio- 

 longitudinal carina as in kaibab, weak but percurrent and cut only by the prin- 

 cipal sulcus, continued on the three succeeding dorsal segments. Tegmina 

 and wings absent. Furcula absent. Supra-anal plate rather narrowly trig- 

 onal-produced, with apex broadly rounded, medio-longitudinal depression 

 decided proximad, lateral concavities decided proximad. Cerci as long as 

 supra-anal plate, of the same type as in pinguis, tapering to the slender apex, 

 which is oblique truncate, the dorsal angle being obtuse-angulate but sharply 

 rounded, the ventral angle acute-angulatc but more broadly rounded, distal 

 portion more slender than in pinguis, very slightly heavier than in kaibab. 

 Subgenital plate conical, lateral margins almost straight to the very feebly ele- 

 vated apex, which is small, slightly produced, entire. Cephalic and median 

 femora slightly inflated, very feebly bowed.
