front of the fastigium but avoids the eyes; vertex gently tumid, the 

 interspace between the eyes broad, equaling the frontal costa, the 

 fastigium broadly, equally, and very shallowly suleate; frontal costa 

 broad, subequnl, with rounded margins, feebly sulcate at and below 

 the ocellus, feebly punctate laterally; eyes as in M.feworatits; antennae 

 ferruginous, more or less considerably and broadly iufuscated apically, 

 about as long (male) or about two-thirds as long (female) as the hind 

 femora. Pronotum enlarging a little from in front backward, more 

 feebly in the male than in the female, the disk as in M.femoratus, the 

 median carina slight but distinct throughout, generally slighter (but 

 only a little) between the sulci, the lateral cariuae obscure, consisting 

 of a rounded angle, the front margin very feebly convex, the hind margin 

 broadly rounded or obtusely rotundato-angulate; prozoua distinctly 

 longitudinal (male) or quadrate (female), generally a third (male) or a 

 fourth (female) longer than the metazoua, with very faint and exceed- 

 ingly sparse punctation, the metazona finely and closely punctate; disk 

 very dark brownish fuscous, rather broadly bordered laterally, including 

 the lateral carinae, with an equal, generally percurrent, fulvo-testaceous 

 or pallid testaceous stripe, usually half as broad as the frontal costa, and 

 which is bordered more or less narrowly and irregularly on the lateral 

 lobes of the prozona with blackish fuscous, fading below into fuscous, 

 except in the sulci. Prosternal spine as in M.femoratus. Tegmina 

 attaining or a little surpassing the hind femora, generally longer in the 

 male than in the female (in a single instance seen, a female, no longer 

 than the femora themselves) brownish or blackish fuscous, the anal 

 vein marked by a slender flavous stripe, the discoidal area not darker 

 than the rest, generally almost clear bat frequently with faint and del- 

 icate mottling; wings hyaline, the cross- veins, except in the inner half 

 of the expanded anal area, fuscous. Fore and middle femora ferrugi- 

 nous, more or less heavily infuscated above; hind femora rather long 

 and moderately stout, ferrugineo-testaceous, the outer and generally 

 the inner faces black above, flavo-testaceous below, the inner half of the 

 upper face thrice very broadly banded with black, the genicular arc and 

 a basal transverse stripe across the lower genicular lobe black on both 

 sides; hind tibiae passing more or less gradually, at varying points but 

 generally near the middle, from purplish at the base to greenish yellow 

 (very rarely red or reddish) at the tip, the patella of the lighter color, 

 followed in lighter examples by a narrow black annulus, the spines black 

 almost or quite to their base, ten to thirteen in number in the outer 

 series. Extremity of male abdomen clavate, rounded, well upturned, 

 the supraanal plate clypeate, with strongly sinuous sides, rectangulate 

 tip, a slender percurrent very deep median sulcus, bounded in the basal 

 half or more by sharp walls, between which and the lateral margins the 

 whole plate is longitudinally hollowed; cerci very broad, laminate, ex- 

 ternally con vex, gently incurved, surpassing the supraanal plate, shaped 

 almost precisely as in M.femoratus but more elongate, and with the
