92. MELANOPLUS COMPTUS, new species. 

 (Plate XX, fig. 2.) 



Of small size and brownish fuscous color. Head dull brownish 

 luteous somewhat uniformly infumated, above much iufuscated with 

 only a feeble mottling of luteous ; vertex feebly tumid, only slightly 

 elevated above the level of the pronoturn, the interspace between the 

 eyes as broad as the first antennal joint; fastigiuin strongly declivent, 

 rather deeply sulcate throughout; frontal costa equal, as broad as the 

 interspace between the eyes, shallowly sulcate at and below the ocel- 

 lus, biseriately punctate; eyes rather large and prominent, much longer 

 than the infraocular portion of the genae; antennae fulvous, more than 

 three-fourths as long as the hind femora. Pronotum brownish fuscous 

 above, luteo-testaceous on lateral lobes, the latter marked above on the 

 prozona by a broad dull piceous stripe sometimes tinged with smoky 

 olivaceous; disk scarcely expanding on the metazona, very broadly 

 convex and passing into the inferiorly vertical Lateral lobes by a well 

 rounded shoulder nowhere forming distinct lateral carinae; median 

 carina obsolete on the prozona; front margin transverse, almost imper- 

 ceptibly einarginate in the middle, hind margin obtusangulate, the 

 angle rounded; prozona subquadrate or feebly longitudinal, distinctly 

 longer than the closely punctate metazona. Prosternal spine short, 

 conico-cylindrical, compressed, erect, very blunt; interspace between 

 mesosternal lobes of male at least three times as long as broad, the 

 nietasternal lobes attingent for some distance. Tegmiua brownish fus- 

 cous, immaculate or very obscurely and feebly maculate in the discoidal 

 area, slender, subequal, scarcely expanded on the costa, surpassing a 

 little the hind femora; wings rather narrow, pellucid, glistening, the 

 veins pale blue on the lower, fuscous or blackish on the upper half. 

 Fore and middle femora but little tumid, luteo-testaceous blotched with 

 fuscous; hind femora luteo-ferruginous, obscured with fuscous above 

 and on outer face, above interruptedly, so as to cause feeble signs of 

 dusky fasciation, beneath chrome yellow, the genicular arc dull luteous, 

 edged only with fuscous; hind tibiae red, narrowly pallid at extreme 

 base, the spines black on apical half, ten to eleven in number in the 

 outer series. Extremity of male abdomen a little clavate, somewhat 

 upturned, the supraanal plate long triangular, the basal three-fifths 

 with well rounded uptilted sides, beyond which the plate is laterally 

 notched and contracted, the apex produced and very acutangulate, the 

 tip blunt, the median sulcus broad and not very deep, terminating with 

 the basal portion; furcula consisting of a pair of depressed, uniformly 

 tapering, acuminate, slightly divergent fingers less than a third as long 

 as the supraanal plate; cerci rather sbort and not very broad, regularly 

 spatulate by the regular, slight and gradual mesial contraction, the 

 apical half rather strongly incurved, externally hollowed, the apex well
