by luteous; vertex rather tumid, considerably elevated above the pro- 

 notum, the interspace between the eyes fully as broad as (male) or 

 considerably broader than (female) the first antermal joint; fastigium 

 steeply declivent, rather shallowly sulcate even in the male; frontal 

 costa hardly reaching the clypeus, slightly narrowed above to meet 

 the fastigium, otherwise subequal, broad, slightly broader than the 

 interspace between the eyes, feebly sulcate or depressed at the ocellus, 

 punctate, seriately at the sides above; eyes moderately large, not very 

 prominent, distinctly longer than the infraocular portion of the genae; 

 antennae luteous, apically becoming slightly ferruginous or fuscous, 

 more than two-thirds (male) or about three-fifths (female) as long as 

 the hind femora. Pronotuin very feebly flaring anteriorly to receive 

 the head, somewhat enlarging posteriorly, the disk passing by a blunt 

 angle into the lateral lobes, the former brownish fuscous, more or less 

 distinctly ferruginous, the latter passing from luteo-testaceous below 

 to fuscous above, the prozona with a broad piceous band which is 

 obliquely cut by a distinct, posteriorly narrowing, sometimes feebly 

 arcuate, luteous stripe, which connects with the luteous field just below 

 the postocular band of the head, a feature more prominent in the female 

 than in the male; median carina percurrent, often black, hardly less 

 distinct on the prozoua than on the inetazona; front margin feebly 

 convex, often with a slight median em argi nation; hind margin obtus- 

 angulate, often nearly rectangulate; prozona slightly longitudinal 

 (male) or quadrate (female), distinctly (male) or hardly (female) longer 

 than the closely punctate metazona. Prosternal spine moderately 

 long, cylindrical, feebly appressed, very blunt (male) or short, conical, 

 appressed, blunt (female), erect; interspace between mesosternal lobes 

 more than twice (male) or only a little (female) longer than broad. 

 Tegniina surpassing more or less, generally considerably, the hind 

 femora, moderately slender, distinctly tapering, brownish fuscous, 

 with distinct quadrate black maculation in the discoid a 1 area. Hind 

 femora testaceous, sometimes tinged with ferruginous, broadly and 

 obliquely bifasciate with blackish fuscous, with a basal patch of the 

 same, the under surface luteous, sometimes faintly flushed with orange; 

 hind tibiae very pale green, becoming more or less pallid or luteous at 

 either extremity, the spines black, except basally, nine to twelve, 

 usually ten to eleven, in number in the outer series. Extremity of 

 male abdomen elougate-clavate, a little upturned, the supraanal plate 

 long triangular, with lateral margins full at the base and scarcely 

 elevated, acutangulate apex,' and slender, rather shallow, median 

 sulcus, bounded by rather slight but distinct walls; furcula consisting 

 of a pair of slender, flattened, parallel fingers, subequal in basal half 

 beyond much narrowed and acuminate, reaching almost to the middle 

 of the supraanal plate; cerci slender, slight, tapering feebly in basal 

 half, about four times as long as broad, apically well rounded, very 

 feebly incurved, hardly upcurved, the outer surface punctate and
