Cakenidium Darlingense, n. sp 



Black, nitid, thorax margined with green, elytra dark violet 

 margined with green. Head large, subnitid, eyes large, promi- 

 nent, preocular angles prominent and rounded, frontal canals deep 

 and moderately diverging behind, the clypeus narrowly and retusely 

 emarginate in the middle, with a prominent tooth on each side 

 bounding the labrum. The labrum itself is short, about one-fifth 

 of the width, and a little emarginate, with six large punctures. A 

 large setigerous puncture occupies the angle caused by the bifur- 

 cation of the frontal canals near the clypeus, and two others are 

 placed one above the eye, the other a little behind the first. The 

 thorax is very slightly broader than the head, narrowly margined 

 on the sides and base, about as long as broad, slightly emarginate 

 on the apex, rounded and narrowed behind into a short basal lobe 

 very slightly emarginate in the middle, and with the median line 

 not reaching the base or apex. Elytra elongate-ovate, the length 

 three times the width, narrower than the thorax, narrowly margined 

 except at the base, with, on each elytron seven or eight almost 

 obsolete punctured striae, a cluster of five or six punctures on the 

 base, a deep puncture near the base about equidistant from the 

 t»ase, suture and humeral angle^ and a similar one near the apex.
