500 Mr. J. SFaly’s Descriptions of 
shining, impunctate. Elytra narrowly oblong-ovate, 
very slightly attenuated towards the apex, the latter 
conjointly subangulate-rotundate ; above convex, rather 
deeply excavated below the basilar space, the excavation 
extending upwards along the inner margin of the 
humeral callus to the base; surface distinctly punctured, 
the puncturing coarser on the sides, very fine towards 
the apex; close to the suture the punctures are arranged 
in a single longitudinal stria; here and there on the 
disk are traces of double rows of punctures. 
Chalcophana eximia. 
Blongata-ovata, postice attenuata, rufo-testacea, ni-

externa excepta) tarsisque nigris; thorace levi, disco 
remote et minute punctato, basi serie unica punctorum 
distinctorum marginato; elytris viridi-eneis, cupreo

Head trigonate, slightly longer than broad; vertex 
very finely and distinctly punctured, impressed on the 
medial line with a longitudinal groove; encarpe thick- 
ened; antenne nearly three-fourths the length of the 
body, the basal joint rufo-testaceous, the rest black ; 
eyes, apices of jaws and the palpi also black. Thorax 
more than twice as broad as long at the base, sides very 
obliquely converging and slightly rounded from base to 
apex, all the angles mucronate; disk shining, very 
sparingly impressed with minute punctures, only visible 
under a strong lens; basal margin bordered with a 
single row of distinct punctures. Elytra much broader 
than the thorax at the base, sides gradually narrowed 
from the base towards the apex, the latter conjointly 
angulate ; above convex, the humeral callus prominent ; 
surface very coarsely punctured, the punctures irregularly 
placed in longitudinal strie; the interspaces rugose, 
nitidous; each elytron with eight rather strongly- 
elevated cost, the three inner ones only visible on the 
hinder disk, the eighth short, placed immediately below 
the shoulder and uniting with the seventh a short 
distance below the humeral callus,
