(TlateXXI, tig. 6.) 

 MelaiiopJiis compact im linvsEUl, MS. 



A medium-sized species, blackish fuscous in coloring, more or less 

 tinged with ferruginous. Head not prominent, rufo luteous more or 

 less clouded with fuscous, with a median blackish ^^uscous stripe above 

 and a i)ostocular piceous band; vertex gently tumid, leebly elevated 

 above the pronotum, the interspace between the eyes considerably 

 broader than (male) or nearly twice as bioad as (female) the basal 

 antennal joint; fasti^rium steeply declivent, sulcate throughout, more 

 deeply in the male than in the female; frontal costa just failing to 

 reach the clypeus, feebly narrowed above but otherwise sube(|ual, as 

 broad as the interspace between the eyes, sulcate at and below the 

 ocellus, biseriately punctate above; eyes not i>rominent nor large, about 

 as long as the intraocular pt)rtion of the genae; antennae red, gradually 

 infuscated apically, in the female more than three-fourths as long as the 

 hind femora. Pronotum stout, gradually enlarging posteriorly, the lat- 

 eral lobes of the prozona with a more or less distinct piceous postocular 

 band, the disk passing into the vertical lateral lober, by a distinctly 

 though slightly angulated shoulder, forming feeblelateralcariuae; median 

 carina percurrentbut nuitb feebler on the i>rozona than or. the metazona; 

 front margin truncate, hind margin obtusangulate : prozona feebly (male) 

 or distinctly (female) transverse, no longer than the ciosely punctate 

 metazona. Prosternal spine rather short and rather stout, much 

 ajipressed, tapering, very Idunt; interspace between mesosternal lobes 

 a little longitudinal (male) or a little transverse (female), the meta- 

 sternal lobes attingent (male) or moderately distant (female). Tegmina 

 surpassing a little the hind femora, moderately broad, brownish fuscous
