feebly flecked with fuscous; vertex very feebly tumid, Dot elevated 

 above the pronotum, the interspace between the eyes rather broad, half 

 as broad again (male) or more than twice as broad (female) as the first 

 .aiiteunal joiiit; fastigium moderately declivent, distinctly (male) or very 

 feebly and broadly (female) silicate throughout; frontal costa about as 

 broad as the interspace between the eyes, subequal, percurrent, plane 

 (male) or convex (female) above, the puncta biseriately disposed, feebly 

 sulcate at and below the ocellus; eyes not large nor prominent, barely 

 exceeding in length the infraocular portion of the genae; antennae ferru- 

 ginous, increasingly infuscated beyond the middle, nearly three fourths 

 (male) or scarcely one half (female) as long as the hind femora. Proiio- 

 tum short, regularly and noticeably narrowing from behind forward by 

 the gradual constriction of the upper portion, the lateral lobes being 

 steeply and obliquely decliveut on the prozona, vertical on the metazona, 

 separated from the nearly plane disk by a tolerably sharp but rounded 

 angle; median carina distinct and sharp on the metazona, indistinct 

 and blunt on the prozona, subobsolete between the sulci; front margin 

 faintly convex, hind margin obtusaugulate, the angle rounded: prozona 

 darker on the disk than the metazona, and on the lateral lobes furnished 

 with a broad piceous postocular band, the disk quadrate (male) or 

 transverse (female), scarcely (male) or not (female) longer than the 

 subruguloso punctate metazona. Prosterual spine moderately long, 

 appressed conico-cylindrical, blunt, retrorse (male) or short, stout, 

 strongly appressed cylindrical, blunt, suberect (female); interspace 

 between inesosternal lobes feebly transverse, narrower than the lobes 

 themselves in both sexes. Tegmiua attaining the tips of the hind 

 femora, moderately broad, tapering, well rounded apically, ruddy fus- 

 cous, with feeblest possible sparse rnaculation in the discoidal area; 

 wings not very broad, pellucid, with apically fuscous veins. Fore 

 femora of male scarcely tuniescent; hind femora dull ferruginous, 

 broadly bifasciate with blackish fuscous, often more or less confluent 

 on the outer face, the genicular arc black; hind tibiae red, the spines 

 black throughout, ten to eleven in number in the outer series. Extrem- 

 ity of male abdomen clavate, upturned, the supraanal plate long trian- 

 gular, the apex acutangulate, the basal half of the sides turned upward 

 and in the middle contracted, with a broad, deep, triangular sulcus in 

 the basal half, bounded by high but rounded walls which unite in the 

 middle of the plate; furcula consisting of a pair of adjacent, parallel, 

 slender, tapering, acuminate, slightly depressed fingers, nearly reach- 

 ing the middle of the supraaual plate; cerci feebly falciform, tapering 

 a little in less than the basal half, the tip a little produced but rounded, 

 the outer surface plane and rather coarsely punctate, not attaining the 

 tip of the supraaual plate; subgeuital plate moderately broad, but con- 

 siderably longer than broad, apically elevated and prolonged, the 

 apical margin broadly rounded, subtransverse. and entire. 



Length of body, male, 18 mm., female, 24 mm.; antenna?, male, 7.5
