in the sexes, the femora only moderately swollen; prosternum trans-
versely, rather finely, not densely and confidently punctate (9),
more closely rugose (cf). Length (cf,9) 4-8-6-3 mm.; width 1.6-
2.0 mm. Missouri and Indiana to Pennsylvania. [Callidium

A Similar to the preceding in form, coloration and sculpture but very
much larger, the antennae with more elongate joints though simi-
larly as long as the body (cf ), and with a notably stouter basal
joint; prothorax more broadly rounded at the sides and less prominent
behind the middle, where however it is likewise widest;
legs differing greatly, long, with large and very stout femora (cf),
or notably small, with very moderate femora (9); prosternum
finely, closely rugose in the former, or finely, remotely punctate
(9). Length (cf,9) 7.0-7.8 mm.; width 2.4-2.6 mm. New

testaceous. Form elongate, rufo-testaceous, with short
sparse pallid pubescence; prothorax slightly shorter than wide,
anteriorly somewhat, posteriorly distinctly, constricted, the sides
rounded, sparsely punctate; elytra dark blue, densely punctate;
abdomen nigrescent; antennae obscure rufous at base. Length 6.3
mm. California (Tejon). [Callidium blandum Lee., Proc. Acad.
Phila., 1859, p. 79] blandus Lee.
Legs deep black, the tibiae and tarsi feebly picescent. Form narrow, convex,
strongly shining, deep black throughout, the prothorax above
and beneath alone paler and testaceous, the pronotum nubilously
bordered with black at apex and base toward the middle; pubescence
everywhere extremely short, inconspicuous; head finely but
strongly, not densely punctate, the eyes very far from divided, the
notch only penetrating two-thirds across; antennae (cf ) moderately
slender, four-fifths as long as the body, blackish, the joints feebly
pallescent toward their bases, the second a little more than half as
long as the third; prothorax only very little narrower than the elytra,
parallel, with very evenly and strongly arcuate sides, nearly as long
as wide, the base and apex subequal, the former scarcely at all constricted;
surface very convex, finely, not densely punctate, with an
elongate and smooth, scarcely convex space at each side of the median
line, which is narrowly impunctate basally but not tumid; scutellum
small, nude, polished; elytra much more than twice as long as wide,
parallel, rather obtusely rounded at apex, the punctures not very
coarse, impressed, separated by about their own diameters; legs
rather short, with moderately but very abruptly clavate femora, not
differing much sexually; tarsi very short. Length (cf, 9) 5-3~
5.8 mm.; width 1.3-1.6 mm. New Mexico densipennis n. sp.
