an elongate-ovate ])atch obliiinely from shoulder to near suture, a rouniled- 

 triangular ]iatt;h behind sbouhlor from outer margin to disc; an irregular baud 

 jnst before middle widest on disc, convex behind, sinuate near suture behind 

 and in front, with a rounded lobe jirojecting forward situated outside the sntural 

 depression: an elongate-ovate postmedian sjiot near suture; an apical area extending 

 laterally from behind middle of margin to apex, irregular and oblique above, with 

 two incisions above which unite and thus separate a spot from the area ; lateral 

 edge entirely tawny-orange, uniting the patches. In picfa the basal patch reaches 

 suture and is produced frontad at suture, while in coronata the patch stands 

 farther back than in n\v, there being a dark basal triangular area in that species.

 p. 153, head rather wider at frontal margin, and pronotnm without a distinct 

 antemediau transverse groove above. Pubescence of upper- and underside clay- 

 colour. Antenna black, the grey basal and apical rings of the segments not marked 

 on the njjperside, and visible below only on the proximal segments ; the first and 

 second segments all clayish grey beneath. Genae, pronotal side-spine, and a large 

 discal pronotal area, divided by a mesial clayish vitta, black. Elytra with a large 

 black antemedian band as in rochrcata, but this band angulate laterally in 

 front ; humeral angle, a posthumeral marginal mark and an irregular one between 

 scutellnm and humeral angle also black ; j)osterior two-fifths clay-colonr, except a 

 large, transverse, comma-shaped, snbapical spot, a short sntural stripe, a longer stripe 

 on the costa corresponding to the third interspace of other Cerambycidae,n,suh\a,tQ\al 

 Z-shaped spot and a smaller snbrotundate one behind it, which are all black. 



Mesosternal intercoxal process projecting ; a small lateral spot on the pro- 

 sterunm, an elongate one on the mesosternal episternum, a streak on the epimerum, 

 a shorter but broad lateral spot on the metasternum, and a transversal basal band 

 on the abdominal segments black ; the abdominal bands are widened at the sides 

 and in the middle, the first and fifth excepted, the first being distinct only laterally, 

 and the fifth being mesially divided.

 a triangular mesial spot), a sjjot behind eye and another above it, as well as a thin 

 mesial vitta on occiput, creamy white. Disc of pronotnm black, except a transverse 

 spot ill basal margin, which spot is triangularly produced frontad; this projection 

 preceded by two mesial dots, one subai)ical, the other nearly median ; side-spine 

 black. Scutellnm creamy white. The creamy white patches and spots of tlie elytra
