5. MELANOPLUS CUNEATUS, new species. 



(Plate X, fig. 5.) 

 Melanoplns citncatus BRUNER!, MS. 



Brownisli testaceous, darker above. Head luteo-testaeeous, witli 

 the lateral ridges of the fastigium black, the posterior part of the 

 vertex with a median triangular blackish stripe, a broken black edging 

 to the upper posterior part of the eyes and, joining it, a black band 

 behind the eyes; vertex tumid, much elevated above the pronotuin, 

 the interspace between the eyes not very broad, about as broad as the 

 basal antenna! joint, the fastigium deeply sulcate; frontal costa sub- 

 equal, rather narrower than the interspace between the eyes, shallowly 

 sulcate excepting above: eyes rather large, prominent, about as long 

 as the iiifraocular portion of the geuae; antennae fulvo testaceous, 

 about three-fourths as long as the hind femora. Pronotum feebly 

 constricted mesially, expanding almost as much anteriorly as posteri- 

 orly, the front margin feebly convex, the hind margin obtusangulate, 

 the lateral lobes lighter colored than the disk, but on the prozoua 

 marked above with a broken blackish fuscous band, the impressed 

 middle line of the posterior section black; median cariua percurrent, 

 but slighter on the prozona than on the inetazona, subobsolete between 

 the sulci, the lateral carinae forming a rounded shoulder on the meta- 

 zona, obsolete on the prozona. Prosternal spine moderately short, 

 appressed conical, blunt, slightly retrorse; interspace between meso- 

 sterual lobes of male half as long again as broad. Tegmina surpassing 

 a little the hind femora, not very slender, subequal, much maculate 

 along the discoidal area but not elsewhere; wings hyaline. Hind 

 femora brownish testaceous, crossed above and externally by two very 

 oblique fuscous bars, which above are premedian and postmedian, the 

 inner and under surfaces pale coralline, the genicular arc black; hind 

 tibiae glaucous with a slender dusky patellar spot, the spines black nearly 

 to the base, nine to ten, usually ten, in number in the outer series. 

 Extremity of male abdomen feebly compressed, not clavate, scarcely 

 upturned, the supraanal plate triangular, either lateral half broadly 

 and shallowly sulcate and separated by sharp but not very high walls 

 from the rather deep and apically narrowing and fading median sulcus; 

 furcula composed of a pair of minute projecting angulations surmount- 

 ing the ridges of the supraanal plate; cerci bent inwards almost from 

 the base, very broad, broadening mesially by their inferior expansion, 

 the lower margin suddenly bent at the middle, so that the apical half 

 narrows rapidly and has an upward direction, well and rather narrowly 

 rounded, even subangulate, at tip, the whole only half as long again 

 as broad and yet longer than the supraanal plate; subgenital plate 

 exceedingly small and of about equal length and breadth, subcouical, 

 with scarcely any trace of an apical tubercle, except that formed by 

 the shape of the plate as a whole.
