One of the smallest if not the very smallest macropterous species of 

 ^lelanoplus known. The general color is a dark griseons, the vertex 

 of the head marked in black and dull yellow in a somewhat radiate 

 fashion, the whole face and sides of head brownish olive or sordini 

 ycHow, flecked more or less abundantly with black: the antennae are 

 l)ale dirty j-ellow, becoming infuscated toward the tip; behind the eye 

 is a bro{.d black baud, often edged with yellow above, which also 

 traverses the ui»per half or less of the lateral lobes, confined to the 

 prozona, und is often enlivened by a small pale quadrate patch in the 

 center of the lobes; the rest of the latter varies from yellow to brown, 

 p.'dest next the margins; the upper surface of the pronotum varies a 

 good deal, but is usually griseous, often with. a median belt of dirty 

 yellow or ferruginous, edged on the front of the nietazona by a pair of 

 oblique, crescentic, longitudinal or converging patches of black. Teg- 

 iniiia cinereous, with alternate minute blocks of yellow and blackish 

 fuscous in the discoidal area, apically changing to scattered ((uadrate 

 fuscous dots. Hind femora below straw-yellow, above dark brown, 

 with a pair of conspicuous, very oblitjue pale bars at the middle and 

 next the base; hind tibiae pale glaucous, occasionally with a faint 

 rufous tinge, becoming paler next the base and straw-yellow at the tip, 

 the spines more or less heavily black-tipped, ten to eleven, rarely 

 twelve, in number in the outer series; hind tarsi yellowish. 



Head rather large, but not elevated, and moderately arched ; inter- 

 space between the eyes scarcely broader than the first antennal joint 

 (male) or broader than the length of the same (female); fastigium 

 steeply declivent, deeply and roundly (male) or shallowly and flatly 

 (female) sulcate, the lateral margins blunt and either slightly (female) 

 or distinctly (male) divergent and then anteriorly convergent; frontal 

 C03ta broad, nearly equal, shghtly broader below than above, tumid 

 (female) or flat (male) above, with a row of puncta on either side, 

 narrowly and rather shghtly sulcate at and just below the ocellus; 

 eyes rather large, moderately prominent, a little longer than (male) 

 or about as long as (female) the iufraocular portion of the genaej
