71. MELANOPLUS ATTENUATUS, new species. 

 (Plate XVII. ti«. H. ) 



Of medium size and very slender, light fcrrngineo fuscous. J lead 

 rather i>rominent, tiavo-testaceous, fuscous above, witii a broad piceous 

 postocular band: vertex moderately tumid, a little elevated above the 

 j)ronotum, the interspace i)etween the eyes about as broad as the first 

 antennal joint: fastigium steeply declivent. distinctly but not deei>ly 

 sulcate; frontal costa percurrent, sube<|ual, faintly narrower above, 

 slightly broader than the interspace between the eyes, faintly depressed 

 at the ocellus, punctate throughout, biseriately above; eyes large, very 

 l)rominent, nearly twice as long as the infraocular jmrtion of the genae; 

 antennae fusco-testaceous. fully four-tifths as hmg as the hind femora, 

 rronotum subeipuil, faintly expanding on the metazona. ferrugineo-tes- 

 taceous more or less infuscated above, tiavous or fusco-tlavous on the 

 sides, with a broad, piceous, i)ostocular band continr'd to the i»ro/ona, 

 the disk gently convex, i)assing by a rather broadly rounded shnuhler 

 into the anteriorly tumid vertical lateral lobes: median carina dis- 

 tinct, percurrent, eijual; front margin feebly convex, hind margin sub- 

 truncate; ju'ozona very longitudinal, nearly twice as long as the sharply 

 and densely punctate metazona. Prosternal spine rather long, feebly 

 conical, very blunt, erect: interspace between inesosternal lobes some- 

 what longer than broad. Tegmina abbreviate, a little shorter than the 

 lu'onotum. attiugentor subattiiigent, elliptical, broadly rounded ai)i(ally. 

 a little less than twice as long as broad, fusco-testaceous. Tore and 

 middle femora somewhat tumid in the nmle; hind femora slender, light 

 ferruginous, dull tiavous beneath, the genicular arc and a basal bar on 

 the lower genicular lobes blackish fuscous: hind tibiae very pale green 

 apically, pale ferrugineoHavous basally. the spines black nearly to their 

 base, twelve to tburteen in number in the outer series. Extremity of 

 male abdomen clavate, considerably recurved, the supraanal plate long 

 triangular, a little and narrowly compressed just beyond the base, the 

 tip acutangulate but well rounded, the lateral margins somewhat ele- 

 vated, the median sulcus lying between sharp but not high walls in the 

 basal two-thirds of the plate, beyiuid which are a pair of more distant, 

 short, subparallel, blunt, longitudinal ridges; furcula consisting of a 

 pair of very slender, tapering and acuminate. divergent fingers, crossing 

 i>carcely the basal fourth of the supraanal plate; cerci very slender and
