204 PllfU EEDiyc.S OF THE SATIOXAL MrSEVM. vol. xx. 



Tht^ mipraanal i)liit<' is regularly trianjruhir witli straijrht sides and 

 acutuiiguhitt' aiH'X, the surface entirely in tiie same plane from base to 

 apex, i. e.,with no apical depression. The turculu in the single known 

 K])eeies is reduced to a pair of very slight rather distant spines, no 

 longer tlian the last dorsal segment. The cerci taper considerably at 

 base, but more by excision of tlu' lower than of the upper margin, and 

 beyond the miildle are 8ube(|ual, hardly in the least incurved, ami api 

 cally angulate. The subgenital plate is of equal breadth throughout 

 and terminates in a postmarginal l)lunt tubercle abov4', the apical nuir- 

 gin being abbreviated, rounded, and entire. 



The single species occurs in the Southern States, east of the Missis- 

 sippi.

(Plate XIV, liK. 1.) 



Of medium size, brownish fuscous, with a decided ferruginous tinge. 

 Head moderately prominent, testaceous or fcrrugineo-testaceous, dotted 

 above with fuscous, the dots mesially forming a stripe, and with a dis- 

 tinct i)ostocular piceous band; vertex rather tumid, distinctly elevated 

 above the pronotum, the intersi)ace between the eyes as broad (male) 

 or fully half as broad again (female) as the first antenna^ Joint; fas 

 tigium steeply declivent, feebly (male) or very feebly (female) sulcate; 

 face more than usually retreating, the frontal costa failing to reach the 

 clypeus, equal, as broad (nuile) or almost as broad (female) as the inter- 

 spac^e between the eyes, sulcate excepting above where it is biseriately 

 punctate; eyes not very prominent, rather large, distinctly longer than 

 the infraocular portion of the geuae; antennae ferruginous, less than 

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

 femora. Pronotum subeciual, expanding a little on the mctazona, the 

 disk ferrugineo-luteous tlecked with fuscous, very feebly convex, pass- 

 ing by a rounded shoulder nowhere forming lateral carinae into the 

 anteriorly tumid vertical lateral lobes, which are of the color of the 

 face, with a broad piceous i)ostocular stripe across the jirozona; median 

 carina distinct on the metazoua, feeble and in the female subobsolete 

 on the prozona; front margin truncate; hind margin obtusangulate; 

 prozona feebly longitudinal (male) or distinctly transverse (female), a 

 little (male) or no (female) longer than the delicately punctate meta 

 zona. Prosterual spine rather long (male) or rather short (female), 

 conical, rather blunt, suberect; interspace between mesosternal lobes 

 nearly half as long again as broad in both sexes, the metasternal 

 lobes approximate (male) or somewhat approximate (female). Tegmina 

 surpassing a little (male) or considerably (female) the hind femora, 

 moderately broad, tapering (more rapidly in the male than in the female), 

 brownish fuscous, the discoidal area lighter at least on the basal half, 

 and tlecked throughout with tolerably large, more or less rounded, dark 

 fuscous spots; wings rather broad, hyaline at base, beyond infumated
