Art. 8. BUPRESTID BEETLES OF MEXICO—-FISHER, 59 
narrowly rounded, the lateral margins finely serrate; humeri rather 
prominent; each elytron with an obsolete basal depression, and a 
very feeble one behind the humeral angle; surface glabrous, sparsely, 
irregularly, and coarsely punctate, the punctures very shallow and 
obsolete; intervals smooth. Abdomen beneath sparsely and irregu- 
larly punctate, the punctures very shallow and obsolete, sparsely 
clothed with very short, recumbent, inconspicuous hairs; intervals 
finely, densely, and obsoletely reticulate-striolate; last segment nar- 
rowly rounded at the tip, with a very feebly triangular emargination 
at the apex, the portion in front of the marginal groove broadly 
rounded at tip. Metasternum more coarsely punctured, and the. 
intervals smoother <t the middie than on the abdomen, and with 
a deep, elongate emargination at the middle of the anterior margin. 
Prosternum glabrous, finely and densely granulated, the granulation 
becoming smoother on the prosternal process; anterior margin nearly 
truncate; prosternal process parallel, sides carinate, the carinae ex- 
panding behind the coxae, and the apex broadly rounded. 
Female.—Differs from the male in having the last abdominal seg- 
ment narrowly rounded at the apex, and armed with 11 rather long 
teeth, which are slightly bent downward and placed close together; 
the median tooth is wider, longer, and broadly rounded at apex; 
balance of teeth narrow, very acute at the apex, and placed obliquely 
on each side of the median tooth. 
Length, 2.5 mm.; width, 1.38 mm. 
Type locality.—Paraiso, Canal Zone, Panama. 
Other locahives——Pedro Miguel, Canal Zone, Panama. 
Type, allotype, and paratype-—Cat. No. 25118, U.S.N.M. 
Described from three specimens, two males and one female. The 
type and allotype were collected by EH. A. Schwarz at the type 
locality, February 5 and 8, 1911; the male paratype was taken by 
the same collecter at Pedro Miguel, Panama, April 17, 1911. 
This species is closely allied to variabils Waterhouse, but differs 
from it in color, by being more convex, head much narrower in front, 
epistoma very narrow, and the antennae nearly contiguous.
