tudinally quadrate ( ? ), about a third longer than the densely but 

 rather feebly punctate metazona. Prosternal spine moderate, cylin- 

 drical, apically tapering, a little retrorse ; interspace between mesos- 

 ternal lobes twice as long again as broad (rj' ) or longitudinally sub- 

 quadrate ( ? ), the metasternal lobes attingent (d ) or subattingent ( ? ). 

 Tegmina slightly longer than the pronotum, attingent or slightly over- 

 lapping, ovate lanceolate, apically acuminate, twice or (especially in 

 the male) sometimes more than twice as long as broad, testaceous or fusco- 

 testaceous. Fore and middle femora a very little tumid in the male,luteo- 

 testaceous marked with fuscous ; hind femora luteo-testaceous, feebly 

 infuscated externally and sometimes on the upper part of the inner 

 face with a pair of fuscous blotdhes, beneath faint orange, the genicu- 

 lation infuscated ; hind tibiae blue, often luteous basally, with a narrow 

 black postgenicular annulus, the spines black with pallid bases, 11-12 

 in number in the outer series. Abdomen testaceous above, flavous 

 beneath the extremity in the male feebly clavate, slightly recurved, 

 the supraanal plate hastate, acutangulate, nearly plane, with a rather 

 pronounced median sulcus on the basal two-thi;ds, its walls not very 

 l)rominent ; furcula reduced to a pair of scarcely perceptible knobs; 

 cerci rather slender, as broad at base as the frontal costa, tapering to 

 less than half the breadth in the basal half, beyond nearly equal but 

 tapering to a blunt lip, hardl\' incurved, and falling much short of the 

 tip of the supraanal plate ; subgenital plate small, simple, of nearly 

 equal width and narrower than long, apically a little pinched above so 

 as to appear faintly tuberculate, the lateral margins meeting apically 

 in an acute angle. 



Length of body, d , 19 mm., ?, 25 mm.; antennae, d, 8.5 mm., 

 9, 7.5 mm.; tegmina, d., 5.25 mm., 9, 6 mm.; hind femora, <d , n 

 mm., 9 , 14 mm. 



19 c?, 14 ? . Gazelle, Siskiyou Co., California, Sept. 5, A. P. 

 Morse. Since description, I have found that specimens from Brown's 

 Valley, Traverse Co., Minnesota, sent me by Prof. Otto Lugger and 

 which I had at first supposed another undescribed form, are of the 

 same species. 



It bears a close general resemblance to Phoetaliotes nebrascensis 

 vohicris. With the next species and M. hurofii, both eastern species, it 

 forms a group apart in the present series, having relatively long teg- 

 mina and very simple male cerci.
