flexed, the prothorax widest slightly before the middle, the thin
edges not or only very feebly crenulate 4
4 Scutellum equilatero-triangular, nearly flat; apical angles of the prothorax
rounded, not at all everted. Form moderately stout and
convex, piceous-black, the elytra rufous, clouded with piceous later-
ally; head feebly impressed, the punctures distinct, moderately
close-set, each with the very minute hair pale and evident; prothorax
one-half wider than long, the sides and base as usual, the
latter broadly arcuate, with the broad feeble median sinus rather
distinctly limited; punctures fine and sparse, the surface broadly,
evenly, rather feebly convex, gradually becoming coarsely but
loosely punctate in the lateral concavity, the moderately wide,
strongly reflexed sides transversely rugose and coarsely punctate;
elytra ( 9 ) sensibly less than twice as long as wide, one-half wider
than the prothorax, evenly oval, evenly but only moderately convex
above, feebly depressed narrowly along the suture, the sides of the
base feebly prominent, the surface alutaceous, the feebly convex
lines separated by broad rugose intervals, over which are scattered
sparse fine punctures, the third and fourth intervals more convex
and not so broad, the lateral margin rather acute and well marked;
abdomen occupying fully half the entire length, minutely, sparsely
punctate; legs nearly as in inferna. Length ( 9 ) 25.0 mm. ;

Scutellum longer than wide, acutely pointed, not tumid; apical angles of
the prothorax everted and more or less prominent 5
5 Body large, much elongated, convex, shining, piceous-black, the
elytra dark rufous, dusky at the sides; head deeply, obliquely
bi-impressed, finely, sparsely punctate; prothorax nearly as in compar
but with the apical angles acutely everted and prominent; scutellum
nearly twice as long as wide, very acute; elytra fully twice as long
as wide, oval, convex, gradually acute behind, the surface but very
faintly alutaceous, the rather wide convex lines separated by intervals
which are only a little wider than themselves, quite as convex
and only very feebly rugulose, the small and sparse punctures throughout
irregular in size and shape, some being rather elongate, this
character being more marked than in compar; abdomen shining,
very obsoletely rugulose, minutely and remotely punctate; legs
long and slender, the hind tibiae evenly and feebly bowed; hairs on
the under side of the tarsi long and deep fulvous-red. Length 27.5
mm.; width 1 1. 8 mm. Texas and New Mexico. [Pelecyphorus elatus
Lee.] elata Lee.
A As in elata but smaller and more slender, the elytra more evidently
striate, black; prothorax slightly shorter than wide, the sides
broadly and gradually reflexed, rounded anteriorly, angulate in
the middle, and, thence to the base, sinuate; base truncate, the
posterior angles almost right; surface medially sparsely and finely,
laterally more coarsely and rugosely, punctate; elytra slightly wider
than the prothorax, elongate-oval, acuminate behind, moderately
deeply punctato-scabrous; striae distinct, broad, moderately
