 elytronim epipleuris basi intus late flavis. 



[Long. 5 lines, lat. 2^ lines. 



The lateral margins of the prothorax and elytra are narrowly, 

 obscurely reddish pitchy ; each elytron bears a large yellow 

 spot which almost reaches both base and apex, and is separated 

 from the lateral margin by only about a fifth of the width of 

 the elytron, its outline next the suture being deeply emarginate ; 

 if the yellow color be regarded as the ground tint of the elytra 

 they would appear to be margined rather widely at the side, 

 and very narrowly in front and behind, with black, and to bei'.r a 

 large common black mark which (viewed with the head of the 

 insect towards the observer) has the appearance of an open 

 umbrella standing up on its handle, the widest part of this mark 

 extending about half-way across each elytron- The head is wide, 

 and short in front of the eyes ; the clypeus is rather deeply emar- 

 ginate ; on either side of the head a wf 11-defined oblique furrow 

 runs (a little within the eye) from the front nearly to the base, — 

 these furrows converging but not nearly meeting hindward. Tlie 

 surface of the head and jirothorax is evenly and finely coriaceous. 

 The latter is slightly and undetinedly uneven on the disc with its 

 front margin stiongly bisinuate and its base nearly straight. The 

 elytra have rather wide, and rather decidedly turned uj*, lateral 

 margins ; their surface Ls coriaceous uniformly with the head and 

 prothorax, and bears also about eight rows of very faintly impressed 

 punctures. The underside is pitchy much variegated with reddish, 

 the darkest parts being the head, thetibite and tarsi, the epipleune 

 of the prothorax, the same of the elytra down their middle part, 

 and the hinder part of the hind body. The conspicuous bright 

 yellow color of the inner part of the base of the epipleurse of the 

 elytra is a striking character. 



This species must resemble aS*. marginata, Castln., from the 

 Paroo River, the descri[)tion of which however (beyond the 

 words " broad, depressed ") deals only with color. In that species
