ward. The prothorax is half again as wide as long, its front al- 

 most truncate, its front angles feeble, its sides gently arched, its 

 hind angles sub-dentiforni, its surface even. The antenna? are- 

 about two-thirds the length of thebody, moderately slender, the basal 

 three joints testaceous, joints 1 and 4 about equal to each 

 other, and each about equal to 2 and 3 together, the latter- 

 two not differing much from each other in length. Tlie epipleune 

 of the elytra though very narrow and obscure behind the middle 

 do not appear to be absolutely non-existent. The tibia' are finely 

 mucronated, the anterior coxal cavities closed. The claws are 

 appendiculated. The basal joint of the hind tibia? equals in lengtli 

 the following three together. 

 Port Lincoln ; not uncommon.

 The puncturation is in general a little less strong and less spai'- 

 ing ; apart from this diiference and its very different pattern and 

 arrangement of colors, the present species scarcely differs from 

 the preceding. Regarding the ground color of the elytra as black,, 

 the red fascia is much wider and less conspicuously angulated 

 than that of J/, angulata : this fascia is so placed that its hind 

 margin is slightly behind the middle of the elytra. I can find no 

 structural distinction except that the epipleura? are even more- 

 obscure behind the middle, but still not entirely wanting ; if 

 careful iy examined under a powerful lens the elytra are seen to- 

 end laterally in (not a single sharp edge like that of a knife blade 

 but) two very fine edges parallel to, and apparently in contact 

 with, each other.

 The sculpture and proportions of the several parts do not seem 

 to difier noticeably from the same in JI. am/ukita, except as fol- 

 lows, viz. : The prothorax is punctured only very obscurely, and 

 for the most part only near the margins, and it has an ill-defined 

 transverse depression (in some examples interrupted near the mid- 

 dle) across the disc ; the elytra are punctured much more finely
