NO. 1124. REVISION OF THE MELANOPLISCUDDEK. 109 



Prouotum subequal, feebly expanding on the metazona, especially in 

 the female, the disk of the prozona often enlivened with the lighter 

 colors of the face, the upper half of the lateral lobes of the prozona 

 occupied by a piceous patch or band, sometimes broken in the female, 

 the disk convex and passing into the vertical lateral lobes by a rounded 

 shoulder, rarely angulate, without forming lateral carinae; median 

 cariua weak, percurrent, subequal, but slightly feebler on the prozona 

 than on the metazona; front margin truncate, hind margin broadly rotun- 

 date, occasionally feebly angulate in the female; prozona slightly longi- 

 tudinal (male) or slightly transverse (female), distinctly longer than the 

 finely punctate metazona. Prosternal spine short and stout, scarcely 

 tapering, very blunt, appressed; interspace between mesosternal lobes 

 fully half as broad again as long (male) or about twice as broad as 

 long, barely narrower than the lobes (female), the metasternal lobes 

 approximate (male) or hardly half as distant as the mesosterual lobes 

 (female). Tegrnina about as long as the pronotum, moderately distant, 

 elliptical, about twice as long as broad, apically subacuminate, fusco-fer- 

 ruginous. Fore and middle femora considerably tumid in the male; hind 

 femora moderately stout, testaceous often tinged with ferruginous, very 

 obliquely bifasciate with fuscous, generally interrupted ou the outer half 

 of the upper face, the under face flavous, verging on orange, the gen- 

 iculation more or less infuscated ; hind tibiae dull greenish, a little paler 

 next the base, with a fuscous patellar spot, the spines black almost 

 to their base, eight to eleven, usually nine, in number in the outer 

 series. Extremity of male abdomen clavate, somewhat recurved, the 

 supraanal plate long hastate with expanded base, roundly augulate 

 sides and rectangulate apex, the lateral margins considerably elevated, 

 the median sulcus deep and conspicuous between high and sharp walls, 

 terminating apically in a cochlearate depression; furcula consisting of 

 a pair of slender, tapering, acuminate, divergent fingers hardly a fifth 

 as long as the supraaual plate; cerci rather broad, gently tapering in 

 the basal half, beyond equal, apically rounded, nearly straight except 

 for being gently incurved, less than three times as long as the middle 

 breadth ; subgenital plate short and very broad, the lateral and apical 

 margins in nearly the same plane, rotundato-angulate as seen from 

 above, entire. 



Length of body, male, 19 mm., female, 20 mm. ; amtennae, male, 6 mm., 

 female, 5.5 mm.; tegmina, male, 4 mm., female, 5.5 mm.; hind femora, 

 male, 10.5 mm., female, 11.5 mm. 



Ten males, eleven females. Mount Lincoln, Colorado, 11,000 to 13,000 

 feet, August 13 (S. H. Scudder; [U.S.N.M. No. 728]). It has also been 

 reported from the "mountains of southern Colorado" by Thomas; and 

 by myself, but erroneously, from Sierra Blanca, Colorado, and northern 

 New Mexico ; for in different papers I have formerly referred to this 

 species what are here described as Melanoplus altitudinum and Podisma 

 The present species has a close general resemblance to Melano- 

 indigens, extending to the abdominal appendages of the male.
