front of tlu* fastifjium but avoids the eyes; vertex j::ently tumid, tlio 

 inters])ac'e between the eyes broad, equaliiij^- tiie frontal costa, the 

 fasti«j:iuni broadly, equally, and very shallowly suleate: frontal eosta 

 broad, subequal, with rounded niarj;ins, feebly suleate at an«l below 

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

 lerruj^iiious, more or less consi<lerably jind broadly infuseated apieally, 

 about as lonj:" (male) or about two-thirds as h>nff (female i as the hind 

 femoia. T*ronotum enlarging a little from in front backward, more 

 feebly in the male than in the female, the disk as in M./emoratK.s, the 

 median carina slight but distinct throughout, generally slighter (but 

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

 (»f a rounded angle, the front margin very feebly convex, the hind margin 

 broadly rounded or obtusely rotundato-aiignlate: luo/ona distinctly 

 longitudinal (nuilei or (juadrate (female), generally a third (male) or a 

 fourth (female) longer tlian the metazona, with very faint and exceed- 

 ingly sparse punctation. the metazona finely and closely jmnctate; disk 

 very dark brownish fuscous, rather broadly bonlered laterally, including 

 the lateral carinae, with an ecjual, generally i)ercurrent, fulvo testaceous 

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

 wiiich 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.J'vmoraius. Tegmiua 

 attaining or a little surpassing the iiind feuKua, generally longer in the 

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

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

 \ ein marked by a slender tlavous stripe, the discoidal area not darker 

 than the rest, geuerally almost clear but freiiuently with faint and del- 

 icate mottling; wings h} aline, the cross- veins, except in the inner iialf 

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

 nous, more or less heavily infuseated above: hind femora rather long 

 and moderately stout, ferrugineo testaceous, the outer and generally 

 the inner faces black above, tlavo-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 i»assing more or less gradually, at varying i)oii»*s but 

 generally liear the middle, from ])urplish at the base to greenish yellow 

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

 followed in lighterexamples 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 sujiraanal plate clypeate, with strongly sinuous sides, rectaugulate 

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

 iialf oi- 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 iticnrved, surpas^sing the supraanal plat?, shajjed 

 almost precisely as iu M./emoratus but more elongate, and with the
