242 Mr. J. S. Baly's Monograph of the 



vertex brassy black ; apex of jaws and the antennae black, the 

 latter slender, nearly half the length of the body, their four basal 

 joints fulvous. Thorax twice as broad as long, sides nearly 

 parallel behind, rounded and narrowed in front, anterior angles 

 acute; above slightly flattened, smooth and shining, disc dis- 

 tantly, sides more closely punctured ; on the surface are six black 

 spots, four just behind the anterior margin and two on the disc. 

 Scutellum triangular, fulvous. Elytra nearly parallel, scarcely 

 wider than the thorax, more than three times its length, their apex 

 acutely rounded, surface coppery, with a brassy tinge, punctate- 

 striate; on each elytron below the shoulder is a large transverse 

 impression. Beneath pale fulvous, the tibiae and tarsi pitchy.

I only know two specimens of this insect ; one in the British 

 Museum, the other in my own Cc^Ilection.

Elongate, subconvex, shining brassy brown, a vertical patch 

 on the head, a dorsal vitta on the thorax, and the scutellum deep 

 fulvous. Head shining, brassy green, finely punctured, on the 

 face are a few coarser impressions ; labrum, three first joints of 

 antennae, a small spot on either side at their base, and a short per- 

 pendicular line on the vertex, fulvous. Thorax twice as broad as 

 long, narrowed from the base towards the apex, rounded near 

 the latter, anterior angles acute, front margin concave, slightly 

 produced in the middle ; surface coarsely but sparingly punc- 

 tured, the sides subvariolose ; in the centre is an obscure ful- 

 vous line, which unites with the vertical spot on the head, and 

 with the pale scutellum to form a longitudinal vitta. Scutellum 

 smooth, rounded, fulvous. Elytra scarcely wider than the 

 thorax, parallel, their sides subsinuate ; surface smooth and 

 shining, indistinctly flattened above, regularly punctate-striate, 

 the interstices minutely and obscurely punctured; on either side, 

 below the shoulders, is a broad, shallow fossa. Beneath brassy 

 brown, the sternum fulvous. 



Var. A. Entirely brassy brown.
