ArT. 8. BUPRESTID BEETLES OF MEXICO—FISHER. L3 
Type, allotype, and paratypes.—Cat. No. 25094, U.S.N.M. 
Described from six specimens, three males and three females, all 
collected at Paraiso, Canal Zone, Panama, by August Busck and EF, 
A. Schwarz during February, March, and April, 1911. The elytra of 
three of the paratypes are of a greenish-bronze color instead of dark 
cupreous as in the type; otherwise they are identical. 
This is a very rotund species, and superficially resembles some of 
the Coccinellidae. It is closely allied to lunifer Waterhouse, described 
from Guatemala, but is of a cupreous or greenish-bronze color above, 
and with a dark arcuate area near the apex. The terminal segment 
of the abdomen of the female is quite different from lwnifer, but re- 
sembles more closely that of laticeps, described by Waterhouse from 
Panama, although differing in other respects from that species. 
PACHYSCHELUS ATROVIRIDIS, new species. 
Male.—Broadly ovate, slightly longer than wide, slightly narrower 
behind than in front, shining, black, with a violaceous and bluish- 
green tinge; surface sparsely pubescent; beneath piceous. 
Head flat and rather deeply embedded in the prothorax, with an 
obsolete median depression on the occiput; surface rather densely, 
coarsely punctate and densely, obsoletely granulated. Pronotum 
moderately convex, about three times as wide as long at middle, 
much narrower in front than behind, widest at base; sides strongly 
obliquely arcuate from base to apical angles, which are nearly rec- 
tangular; anterior margin broadly, arcuately emarginate; base feebly, 
obliquely truncate to the elytral lobe, where it is acutely, arcuately 
emarginate, then transversely truncate in front of scutellum; hind 
angles nearly rectangular, not projecting beyond the humeral angles 
of the elytra and fitting closely to them; surface feebly depressed 
near the posterior angles, sides densely, finley granulated and sparsely 
punctate, the punctures large, shallow, and open on one side, becom- 
ing obsolete on the disk, very sparsely clothed with short, inconspicu- 
ous cinereous hairs. Scutellum obsoletely granulated, and glabrous, 
with the anterior angles acutely rounded. LElytra as wide as prono- 
tum at base, widest at the middle; humeral angles obtuse; sides 
broadly arcuate, more attenuate posteriorly to the tips, which are 
rather broadly, conjointly rounded, the lateral,margin entire, and 
when viewed from the side is broadly arcuate from humeral angle to 
the apex; each elytron with a rather broad, shallow depression at the 
base, and a deeper one between the humerus and lateral margin, 
extending along margin from the humeral angle to the middle; surface 
sparsely and rather coarsely punctate, sparsely clothed with irregular 
patches of recumbent cinereous pubescence, which is arranged longi- 
tudinally, and each elytron with a broader, conspicuous spot at the 
middle a short distance from the suture. Abdomen beneath slightly
