ART. 8. BUPRESTID BEETLES OF MEXICO—-FISHER. 5 
rower in front than behind, widest at the base; sides feebly arcu- 
ately attenuate from base to anterior angles, and narrowly margined ; 
anterior angles rather acute; posterior angles rectangular; anterior 
margin broadly arcuately emarginate, with an obsolete Jobe at mid- 
dle; base transversely truncate to near middle of the elytron, then 
feebly sinuate and turning obliquely backward to the scutellum, in 
front of which it is truncate; surface without depressions, rather 
densely and irregularly punctate, the punctures rather shallow and 
well separated; intervalssmooth. Scutellum very small, smooth, and 
triangular. Klytra moderately convex, slightly wider than pronotum 
at base; humeral angles obtusely angulated; sides parallel to the mid- 
dle, then arcuately attenuate to the tips, which are conjointly nar- 
rowly rounded, with the lateral margins entire; each elytron with 
a broad, very shallow depression at the base, and a deep, elongate 
one behind the humerus along the lateral margin; surface without 
lateral carina, densely and coarsely punctate, the punctures deep 
and confluent at the base, but becoming finer and more widely sep- 
arated toward the apex ; intervals smooth. Abdomen beneath rather 
densely marked with shallow ocellate punctures, which are denser on 
the first segment and somewhat confluent at the sides; intervals 
obsoletely reticulate-striolate ; last segment broadly rounded at apex. 
Prosternum® sparsely and coarsely punctured; anterior margin 
broadly rounded ; prosternal process rather narrow, slightly expanded 
behind the coxal cavities, and broadly rounded at apex. 
Length, 2.5 mm.; width, 1.25 mm. 
Type locality.—Porto Bello, Panama.

Described from a single specimen collected by August Busck, 
March 8, 1911. 
TRACHYS CONCINNA, new species. 
Elongate, moderately convex, broadly rounded in front, attenuate 
posteriorly, and slightly narrower behind than in front, glabrous and 
strongly shining; head and pronotum green, the former strongly 
aeneous on the front; elytra green with a strong cyaneous tinge; 
beneath piceous. 
Head nearly flat, rather deeply and broadly depressed on the front, 
with a rather deep round depression behind the antennal cavities; 
surface irregularly and coarsely punctate, the punctures widely sep- 
arated, and becoming finer toward the epistoma; intervals smooth; 
epistoma wide between the antennae, the anterior margin deeply, 
arcuately emarginate; antennae rather short and entirely piceous. 
Pronotum slightly convex, two and one-half times as wide as long, 
distinctly narrower in front than behind, widest at the base; sides 
obliquely attenuate from base to anterior angles, and narrowly 
margined; anterior angles rather acute; posterior angles rectangular;
