the color of the upper surface of the body and have faint fuscous indi- 

 cations of bifasciation above; hind tibiae glaucous, but at the base yel- 

 lowish with a glaucous or fusco-glaucous annulation; spines black with 

 a pallid base, usually eleven in number in the outer series. The upper 

 surface and sides of the abdomen are uniform in fcint, the sides unmarked 

 by any black band. 



Length of body, male, 19 mm., female, 27 mm.; antennae, male, 7.75 

 mm., female, 8 mm.; tegmina, male, 5 mm., female, 6 mm. ; hind femora, 

 male, 10.25 mm., female, 14 mm. 



Ten males, 21 females. Texas, Belfrage (U.S.N.M. Eiley collec- 

 tion); Dallas, Texas, Boll (same; S. H. Scudder). 



In general appearance and in most points of its structure this species 

 resembles M. discolor. It may at once be distinguished from it by the 

 shape of the tegmina and the male cerci and by the color of the hind 

 tibiae.

Brownish fuscous with a ferruginous tinge. Head feebly prominent, 

 yellowish brown, heavily mottled with dusky brown in small spots, 

 often deepening (especially above) to blackish brown; vertex feebly 

 tumid, elevated but slightly above the pronotum, the interspace 

 between the eyes narrow, not (male) or scarcely (female) broader than 

 the first antennal joint ; fastigium very steeply declivent, deeply sulcate 

 throughout; frontal costa narrow, scarcely wider than the interspace 

 between the eyes, equal, percurrent, sulcate at and below the ocellus; 

 eyes large and prominent, in the male as high as the vertex, much 

 larger than the infraocular portion of the genae; antennae castaneous, 

 gradually infuscated apically, nearly three fourths (male) or nearly 

 two-thirds (female) as long as the hind femora. Pronotum brownish 

 yellow, more or less infuscated above, regularly expanding posteriorly, 

 very slightly in the male, noticeably in the female, the disk feebly 

 convex transversely and passing by a tolerably distinct but smoothed 

 angle into the vertical lateral lobes, which in the male are marked 

 with an exceptionally large piceous spot on the upper portion of the 

 prozona, especially on the anterior section a mark which is only indi- 

 cated in the female in dull fuscous and is much broken or subobsolete; 

 median carina equally distinct throughout; front and hind margins 

 truncate, the latter distinctly emarginate in the middle; prozona longi- 

 tudinal, nearly twice as long as the more finely punctate metazona. 

 Prosternal spine rather short, erect, lobate, very strongly appressed, 

 well rounded, the posterior face flat; interspace between mesosternal 

 lobes slightly longer than broad (male) or quadrate (female), the 

 inetasternal lobes subattingent (male) or approximate (female). Teg
