NO. 1124. REVISION OF THE MELANOPLI SCUDDEB. 155 



Bruner states that it also occurs "across the line in Mexican territory 

 for some distance," and that it is confined to river bottoms, where it 

 feeds on low vegetation, but is rarely seen on the ground. 



ii. MELANOPLUS FLAVESCENS, new species. 

 (Plate XI, fig. 1.) 



Uniform pale flavous tinged with green, the upper part of the lateral 

 lobes with a broad olivaceous baud, extending from the eyes across 

 the prozona and feebly marking the lateral carinae of the metazona. 

 Head uniform in coloring and, except for the band mentioned, as light 

 above as below; vertex gently tumid, the interspace between the eyes 

 moderate, scarcely narrower than the frontal costa, the fastigium 

 descending with the curvature of the vertex, rather deeply and broadly 

 sulcate throughout; frontal costa prominent above, moderately broad, 

 equal, percurrent, deeply sulcate excepting above but with rounded 

 margins, above seriately punctate at the sides; eyes rather large and 

 rather prominent; antennae almost as long as the hind femora (male), 

 the first two joints flavous, the rest salmon red. Pronotum subequal, 

 feebly enlarging at the metazona, tlie front margin feebly convex, the 

 hind margin obtusely angulate, the angle rounded, the disk gently con- 

 vex on the prozona with no lateral carinae, on the metazona plane 

 with obscure rounded lateral carinae, the median carina distinct 

 though slight on the metazona, wanting in front; prozona distinctly 

 longitudinal, smooth, a third longer than the closely punctate metazona. 

 Prosternal spine rather long, regularly conical, erect, blunt tipped; 

 interspace between mesosternal lobes of male very slender, many times 

 longer than broad, the metasterual lobes attingent over a wide space. 

 Tegmina slender, very feebly tapering, well rounded apically, surpass- 

 ing considerably the hind femora, greenish-yellow at base, nearly pel- 

 lucid on apical half, without markings; wings pellucid with a scarcely 

 perceptible glaucous tinge, the veins and cross veins fusco-glaucous. 

 Fore and middle femora flavous with a tinge of olivaceous; hind femora 

 golden yellow on the outer face, growing pallid below ; elsewhere flavous 

 with a distinct fulvous tinge on lower and inner sides, the genicular arc 

 testaceous, stained with fuscous; hind tibiae glaucous, pallid at extreme 

 base, the spines pallid on basal, black on apical half, ten in number in 

 the outer series. Extreini ty of male abdomen feebly clavate, upturned, 

 the supraanal plate obscurely clypeate, the lateral margins raised con- 

 siderably throughout, pinched just before the middle and just before 

 the tip, and so somewhat torqueate, the median sulcus only apparent 

 and then slight in apical half; furcula consisting of a pair of large, 

 broad, strongly depressed, longitudinally arcuate plates, which, meas- 

 uring from the base of the last dorsal segment, are about twice as long 

 as broad, in the basal half attingent, in their apical half strongly and 

 roundly excised interiorly, apically obliquely and broadly truncate, ter- 

 minating acutely at the inner hinder angle, and hardly reaching the
