The liead is shining black, impimctate, or nearly so ; the- 

 protliorax is equally wide before and behind, about twice and a 

 half as wide as long, with the sides gently arched, the angles 

 all rounded off. The elytra are five times as long as the thorax,, 

 but not wider than it, their surface rather densely covered with 

 whitish hairs. In some specimens there is a tendency to 

 fuscous clouding about the front and hinder part of the thorax. 

 The underside is shining black. 



Near Port Lincoln ; generally obtained by sweeping low- 

 scrub.

The yellow markings on the head consist of a circular ring 

 (interrupted in some examples) touching both the eyes, and a 

 spot within it (sometimes obsolete) ; the front of the clypeus 

 and the labrum also are yellow (black-lined in some examples). 

 The thorax has a wide yellow margin all round except at the 

 middle of the base (in some examples this margin is infuscate 

 along the front). The anterior elytral fascia has the middle- 

 (longitudinally) of its narrowest part at about the middle 

 (longitudinally) of the elytra but is dilated (a little backward 

 and strongly forward) on the suture and the margins, running 

 up the suture nearly to the scutellum. At its narrowest part 

 its width about equals the length of the basal joint of the 

 antennae ; hence its front and hind margins are on each elytron 

 concave, the front being strongly and evenly so, the hind less 

 evenly and much less strongly. The hinder elytral fascia 

 occupies the apex, commencing on either side at a distance- 

 from the sutural angle about equal to the length of the hind 

 tarsus and being widely and squarely produced up the suture 

 about half-way to the hinder edge of the anterior fascia. The 

 basal two joints of the antennaD are bright testaceous, the- 

 remainder more or less pitchy. The following parts of the 

 underside are yellow — the presternum (except sometimes the 

 anterior coxfe) a narrow hind margin to all the ventral seg- 

 ments except the last, and the middle part (sometimes very 

 narrowly) of the basal two segments. The front legs, the in- 

 termediate tibiae, and the extreme apex of the hind tibiae are- 

 testaceous. The tarsi (except the front ones) are more or less 

 pitchy. The basal joint of the antennae forms an elongate- 

 triangle placed on the end of a short cylindric stem ; its apex:
