ArT. 8. BUPRESTID BEETLES OF MEXICO—-FISHER. 27 
slightly from the type in having the upper surface of a more brown- 
ish-violaceous color, was collected by A. H. Jennings at the type 
locality April 10, 1911. 
PACHYSCHELUS SULCIFRONS, new species. 
Male.—Broadly cuneiform, considerably longer than wide, strongly 
narrowed posteriorly, shining, uniformly dark aeneous above; surface 
moderately pubescent, the pubescence forming transverse undulating 
fasciae on the elytra; beneath piceous. 
Head moderately convex, longitudinally grooved from occiput to 
epistoma, the groove rather deep on the front and vertex, becoming 
feebly defined on the occiput; surface sparsely, obsoletely punctate, 
and sparsely clothed, except on the front, with rather long cinereous 
hairs; intervals smooth except near the epistoma, where they are 
finely granulated. Pronotum moderately convex, three times as 
wide as long at middle, much narrower in front than behind, widest 
at the base; sides strongly, obliquely arcuate from base to apical 
angles, which are nearly rectangular; anterior margin broadly and 
rather deeply, arcuately emarginate; base nearly truncate, acutely 
emarginate; at elytral lobes, and obsoletely emarginate in front of 
scutellum; hind angles acute, projecting very slightly beyond the 
humeral angles of the elytra and fitting closely to them; surface 
broadly, obsoletely depressed toward the sides, and rather densely 
punctate, the punctures large and very shallow, becoming finer 
and obsolete on the disk, sparsely and irregularly clothed with 
long, recumbent, cinereous hairs. Scutellum smooth and glabrous, 
with the anterior angles acute. Elytra as wide as pronotum at 
base; humeral angles obtusely rounded; sides parallel to basal third, 
then abruptly, obliquely attenuate to near the tips, which are con- 
jointly broadly rounded, the lateral margin strongly serrate, and, 
when viewed from the side, is nearly straight, except for an abrupt 
sinuation for the posterior femora; each elytron with abroad, shallow 
depression at the base, and a narrow, deeper one between the 
humerus and lateral margin, extending along margin from the 
humeral angle to a broad deep depression behind the humerus; sur- 
face finely, rather densely punctate, and sparsely, irregularly clothed 
with rather long, recumbent, yellowish pubescence, the pubesence 
on each elytron forming designs as follows: An elongate area 
behind the scutellum; a narrow fascia extending from humerus 
obliquely backward toward the suture; a transverse fascia at the 
middle, commencing at the margin just behind the depression, it 
extends downward, then obliquely upward and joining the fascia from 
the humerus, and then descends again to the suture; the posterior 
fascia, commencing from the margin at apical fourth, extends trans- 
versely to the middle, then horizontally toward the base, and then
