the middle, and with pale markings which are bright yellow in the 

 male and greyish and rather indistinct in the female. 



The body is moderately elongate, and strongly channelled 

 down the middle of the back. The eyes are prominent, the clupeus 

 considerably dilated anteriorly and distinctly emarginate. The 

 protliontx is about as broad as it is long, the sides nearly parallel 

 behind and the posterior lobe feeble. The sides of the elytra are 

 rather strongly excised behind the shoulders. 



c? . The ochreous markings form two longitudinal lines upon 

 the head ; a V-shaped median mark upon the pronotum extending 

 from the front margin to beyond the middle, a curved lateral line, 

 generally interrupted, extending from the median angulation of 

 the side margin to the middle of the base, and occasionally uniting 

 with the V-shaped mark; the whole periphery of the scutellum ; 

 a small spot below the shoulder of each elytron, a larger one at 

 the middle of the suture and a transverse apical line. The middle 

 of the pygidium and the margins of tlie abdominal segments at 

 the sides are also broadly ochreous. The club of the antenna is a 

 very little longer in the male tlian in the female. 



The legs are frequently, but not invariably, red in the male and 

 black in the female. The latter is similar to the male but the 

 pale markings consist of a greyish pubescence much more indefinite 

 than the yellow pattern of the other sex.

Black and opaque, with the front of tiie clypeus, the antennse 

 and legs testaceous red, the femora partly black ; the elytra 

 more or less red and the upper siu"face decorated with the 

 following yellow markings : — two longitudinal lines upon the 

 head ; a lateral line upon each side of the prothorax extending 

 from the basal lobe to the lateral angulation and sending a branch 

 to the hind angle, a V-shaped central mark and an intermediate 

 spot on each side — sometimes produced to connect the lateral 

 and discoidal lines ; the base and apex of the scutellum ; and 

 upon the elytra a juxta-scntellar spot on each side, a common 

 median spot slightly produced forward on each side, an apical 

 mark produced at the suture and two lateral spots. There is a 

 large spot upon the pygidium and the abdominal segments are 

 narrowly edged with yellow at the sides. 



The form is rather short and broad and gently grooved along 

 the middle line of the back. The chjpeus is gently excised in 

 front ; the profhora.v is as long as broad, the sides parallel beliind 

 and the posterior lobe not strongly marked. The elijtra are 

 moderately excised at the sides behind the shoulders. The
