A very distinct species belonging to the same subgenus as 

 fraternum and unispina, but also showing tendencies toward 

 bradleyi. In the unispinose genicular lobes of the caudal femora 

 it shows affinity to fraternum and unispina, but the much greater 

 size, form of the stridulating field of the male tegmina and other 

 features remove it from their immediate vicinity. Of the two 

 it is nearer unispina, which, however, also differs from superbum 

 in having acuminate cerci in the male. It resembles bradleyi 

 somewhat in general plan of the stridulating field but the de- 

 tails are quite different and the cerci and lateral lobes of the 

 pronotum as well as the caudal genicular spines are different 

 from those found in bradleyi. The female sex is not known.

Description oj Type. — Size moderately large; foi'm subcompressed, elongate. 

 Head with the plane of the occiput and fastigium horizontal, the latter well 

 rounded into the outline of the moderately retreating face when viewed from the 

 lateral aspect; fastigium moderately broad, arcuate dorsad in transverse sec- 

 tion, cephalic outhne blunt arcuate, the lateral margins, when seen from the 

 cephalic aspect, moderately concavo-arcuate convergent ventrad, the ventral 

 point truncate and closely in contact with the fastigium of the face; eyes nearly 

 circular in basal outline, which is fairly flattened cephalad, the depth of the eye 

 but faintly more than half that of the infra-ocular portion of the genae, when 

 viewed from the dorsum the eyes are not prominent and are appreciably 

 flattened; antennae at least twice as long as the body, proximal joint with a 

 very distinct distal rounded lobe on the internal face. Pronotum faintly 

 sellate, the dorsal line, when seen from the lateral aspect, horizontal on the 

 prozona and faintly ascending on the metazona, the greatest dorsal width of 

 disk of pronotum contained one and one-half times in the length of same; 

 cephalic margin of pronotal disk very faintly arcuato-emarginate, caudal mar- 

 gin of pronotal disk regularly arcuate; prozona constituting slightly less than 

 two-thirds the length of the pronotal disk, separated from the metazona by a 

 weakly impressed transverse depression, a weak medio-longitudinal sulcus 

 faintly indicated on the caudal section of the prozona and somewhat more 

 strongly on the metazona; lateral lobes of the pronotum broadly rounding into
