This species is more ( losely related to alacris than to any other of 

 the Mrriiiiriit, hut it is readily distinguished by the very different ver-

Vertex hori/onlal, longer than broad, semi-elliptical, medianly con- 

 vex with a very distinct carina, laterally sulcate (female) ot; extc-nded 

 into lamina (male), with the margins linuted by lateral carin.'e. The 

 lateral foveohe are wanting, 'i'he frontal costa is sulcate throughout 

 with slightly divergent heavy lateral ( arina' exci'pt at thi.' immediate 

 apex where it is nuich constricted. I'lu' fact' is very de( livent and 

 straight or a very little sinuate on ac<()iint ol the prominence of the 

 frontal costa bi'tween the antenna'. 'i'liese are very slightly tricpiet- 

 rous and very much flattened and expanding basally, eijualing the 

 short diameter ol the eye nearly (n)ale) or (piite (female) and strongly 

 acuminati'. They i'(|ual tiie head and pronotmu in length (female) or 

 greatly excet-d them (male). The pronolum is but little longer than 

 the head. its disk is nearly plain, slightly elevated toward the me- 

 dian (arina which is distinct and ( ut only oiu c nmch behind the 

 middle by the principal sulcus vvhi( h alone is apparent upon the disk. 

 The lateral (arina' are distinct, |)arallel, cut by the principal suhais 

 oidy. The posterior margin of the metazone is straight, 'i'he lateral 

 lobes of the pronotum are vt'rtic;al, slightly convex above, with the 

 anterioi- and posterior margins strongly ol)li(|ue, the one straigiit, tlie 

 other sinuate just above the posterior lower angle, whi( h is sharp and 

 sub-rectangular. 'I'he lower margin is nearly straight and horizontal. 

 'I'he mesosternal lobes are sc-jjarated by a sjjace longer tlian broad (fe- 

 male) or by a linear ridge with a (U'C]) pit on either side (male), i'he 

 wings in both sexes and the tegmina (female) are abortive or they are 

 ■well developed. In the male the sca])ular area is enlarged with prom- 

 inent cro.ss veins. 'I'he jjoslerior i\'mora are slender, not banded. The 

 jwsterior tibi;v lias the apical sjxu-s on tin- inner side not very ime([ual.
