NO. 1124. REVISION OF THE MELANOPLI SC UDDER. 223 



47. MELANOPLUS MERIDIONALIS, new species. 

 (Plate XV, fig. 2.) 



Fu sco-ferruginous, more or less lutescent beneath. Head not promi- 

 nent, fusco-ferruginous above, elsewhere dark olivaceous, except a 

 piceous postocular band, the vertex gently tumid, slightly elevated 

 above the pronotum, the interspace between the eyes rather broad, 

 much broader than, in the female fully half as broad again as, the first 

 antennal joint; fastigium rapidly declivent, abruptly broadened in 

 front, very shallowly sulcate throughout; frontal costa broad, sub- 

 equal, slightly contracted above in the male, failing to reach the clypeus, 

 rather broader than the interspace between the eyes, feebly sulcate at 

 and below the ocellus, densely punctate; eyes of moderate size, mod- 

 erately prominent in the male, longer than the infraocular portion of 

 the genae; antennae ferruginous, slightly infuscated apically, about 

 three-fourths (male) or nearly two-thirds (female) as long as the hind 

 femora. Pronotum fusco-ferruginous above, luteous or olivaceo-luteous 

 on the lower half of the lateral lobes, the upper half on the prozona 

 brownish fuscous, deepening below into piceous, or wholly dull piceous; 

 subequal, scarcely expanding on the metazona, the disk broadly con- 

 vex, passing almost insensibly, but with a very bluntly rounded angle, 

 into the vertical lateral lobes, the median carina slight, percurrent, and 

 similar throughout; transverse sulci feeble, not cutting the median 

 carina; prozona very sparsely and feebly punctate, longitudinal (male) 

 or longitudinally subquadrate (female), one-third (male) or one fourth 

 (female) longer than the obscurely and finely punctate metazoua. 

 Prosternal spine moderately long (male) or rather short (female), 

 con ico- cylindrical, appressed, blunt; interspace between mesosternal 

 lobes nearly twice as long as broad (male) or slightly transverse 

 (female). Tegmina broad oval, shorter than the prouotum, apically 

 broadly rounded and slightly emarginate, brownish fuscous. Hind 

 femora fusco-ferruginous, the upper carinae often fuscous, the inferior 

 basal half of the outer face often gradually lutesceut, the inferior face 

 and base of inner face fulvous or roseate, the geuiculation, including 

 most or all of the lower genicular lobe, blackish; hind tibiae glaucous, 

 often more or less diffusely infuscated basally, sometimes lutescent 

 apically, clothed with rather long pile, the spines black with pallid 

 base, ten to eleven in number in the outer series. Extremity of the 

 male abdomen clavate, much upturned, the supraaual plate broad tri- 

 angular, with nearly straight, narrowly and slightly raised lateral 

 margins, slightly depressed faintly acutaugulate tip, and a short, tri- 

 angular, rather deeply impressed, basal, median sulcus; furcula con- 

 sisting of a pair of rather large, thickened, brief, lobate expansions of 

 the last dorsal segment, overlying the bases of the apically convergent 

 ridges, which bound the median sulcus of the supraanal plate; cerci
