ART. 8. BUPRESTID BEETLES OF MEXICO—FISHER. 85 
anterior margin broadly, arcuately emarginate; base transversely 
truncate to near middle of elytron, then feebly sinuate and turning 
obliquely backward to the scutellum, in front of which it is truncate; 
surface strongly flattened at the sides (very narrowly at the middle), 
but feebly expanding to the anterior angles; posteriorly the depres- 
sion is very broad and deep, extending internally as far as the basal 
depressions on the elytra, these depressions causing a subarcuate 
elevation at the middle extending from the disk to near the lateral 
margin, sparsely punctate, the punctures rather coarse on the disk, 
but becoming obsolete toward the sides; intervals nearly smooth, 
but becoming finely and obsoletely reticulate-striolate in the depres- 
sions. Scutellum smooth and broadly triangular. Elytra rather 
strongly convex, as wide as pronotum at base, widest at middle; 
humeral angles obtusely angulated; sides feebly sinuate at basal 
third, slightly, arcuately rounded at middle, then strongly, arcuately 
attenuate to the tips, which are rather subtruncate, the lateral mar- 
gins entire; each elytron with a broad, obsolete depression at the base, 
and a deep, narrow one between the humerus and lateral margin, 
extending along the margin from the humeral angle to the middle 
and becoming broader behind the humerus; humeri rather promi- 
nent; surface slightly wrinkled at the sides, and coarsely punctate, 
the punctures widely separated and arranged in rows, and becoming 
more obsolete toward the apex; intervals finely and sparsely punc- 
tured. Abdomen beneath finely and obsoletely punctate, the inter- 
vals finely and densely reticulate-striolate, except on the first segment, 
where the surface is rugose, the rugae coarse and widely separated; 
last segment broadly rounded at apex. Prosternum finely and very 
sparsely punctated; intervals smooth: anterior margin truncate. 
Metasternum with a few very coarse punctures at the middle, and 
with coarse, widely separated rugae at the sides.
