Arr. 8. BUPRESTID BEETLES OF MEXICO—FISHER. O5 
mencing at margin just behind the impression, it is directed down- 
ward to the middle, then upward, and joined anteriorly by a short 
fascia, then descending again to the suture; a narrow fascia com- 
mencing from the margin at apical fourth, extending obliquely up- 
ward to near the suture, then turning obliquely downward to the 
suture; there are also a few obsolete hairs near the apex. Abdomen 
beneath moderately convex, sparsely and obsoletely punctate, the 
punctures very shallow and open on the one side, sparsely clothed 
with a few very short, recumbent, cinereous hairs; intervals finely 
and densely reticulate; last segment broadly rounded, with a feeble 
tooth at apex, the portion in front of marginal groove acutely rounded, 
with a sharp tooth at the tip. Elytral epipleura narrow. Meta- 
sternum more coarsely and densely punctured than abdomen, and 
broadly arcuately emarginate in front. Prosternum feebly, arcuately 
emarginate in front; prosternal process about three times as wide as 
the coxal cavities, sides feebly expanded behind the coxae, and very 
broadly rounded at the apex; episternum short, flat, and triangular. 
Prothoracic epipleura wide and nearly flat, with a deep, narrow groove. 
behind the antennal groove; lateral margin nearly rectangular, be- 
coming more acute posteriorly; antennal groove deep and rather 
wide, following the suture between the episternum and epipleura, 
extending into the latter to about the middle, and parallel to the 
lateral margin. 
Female.—Differs from the male in having the last abdominal 
segment strongly, narrowly produced, and very widely, deeply, rec- 
tangularly emarginate at apex, with four sharp subequal teeth ar- 
ranged obliquely on each side of the emargination, the ventral sur- 
face with a moderately deep, longitudinal groove, extending from 
the apex to near the middle. 
Length, 2.5 mm.; width, 1.7 mm. 
Type locality.—Paraiso, Canal Zone, Panama. 
Type, allotype, and paratype.—Cat. No. 25101, U.S.N.M. 
Described from three specimens, one male and two females, all of 
which were collected by EK. A. Schwarz at the type locality. Male 
collected January 27, 1911; females, January 16 and April 18, 1911. 
PACHYSCHELUS ATRIFRONS, new species. 
Male.—Broadly cuneiform, considerably longer than wide, strongly 
narrowed posteriorly, shining, uniformly piceous, with a bluish-vio- 
laceous tinge above; surface sparsely pubescent, the pubescence 
forming narrow transverse fasciae on the elytra; beneath piceous. 
Head moderately convex; front feebly, longitudinally grooved; 
surface with a few obsolete punctures, from which arises a short 
cinereous hair; intervals obsoletely granulated on the front, becoming 
smooth and shining on the occiput. Pronotum rather strongly con-
