MEMOIRS ON THE COLEOPTERA
antennse (9 ) slightly longer than the body, the twelfth joint slender,
finely pointed, barely a third as long as the third, three-fourths as
long as the eleventh. Length (9 ) 10.0 mm.; width 2.7 mm. New
Mexico : (locality unrecorded) brevicollis n. sp.
Prothorax less abbreviated, never more than one-half wider than long. .
8
8 Male with the well defined black area of the hypomera or inflexed
flanks of the prothorax separated from the anterior margin by a
sharply denned red band 9
Male with this equally well defined black area solid to the apical margin;
entire prosternum as in the preceding, deep black 10
9 Prothorax moderately coarsely, very closely punctate, the impunctate
line variable but never well defined. Male with the antennse very
slender, two-thirds longer than the body, the joints decreasing very
slightly in length, twelfth arcuate distally, very slender, distinctly
longer than the eleventh; subbasal spots of the elytra well developed,
the submedian transverse, sometimes slightly prolonged posteriorly
on the suture, the subapical suboval, moderate, isolated or oblique
to the suture. Female with the antennae not less slender, a fourth
longer than the body, the last joint two-thirds as long as the eleventh
and very much more slender; subbasal elytral spots as in the male,
the two more posterior also similar but much larger, broadly uniting
on the suture and connected longitudinally by a black sutural line;
longitudinal distance between the spots much greater than their
own length. Length (cf 2,9 i) 11.5-12.2 mm.; width 2.8-3.3 mm.
New Mexico (Jemez Springs) medialis n. sp.
A Prothorax as in the preceding. Male with the elytra much shorter
and more parallel than in medialis, with the subbasal spots not
quite so large, the submedian very large, oblong, obliquely attaining
the suture very broadly but not prolonged, the subapical
similarly large but rounded, broadly attaining the suture, the
anterior outline of the combined spots sinuate suturally; antennas
still more slender, barely one-half longer than the body, the outer
joints relatively much shorter and more rapidly decreasing, the
last but very little longer than the eleventh; hind tibiae unusually
coarsely punctate. Length (cf, 9) 9.5-12.0 mm.; width 2.6-3.0
mm. New Mexico (Jemez Springs) bifasciata n. subsp.
10 Prothorax similar. Male with the antennae almost similar throughout,
the subbasal spots of the elytra large, elongate-oval, the submedian
very large, broadly attaining the suture, the subapical
similarly very large, the combined spots forming a large area which
gradually narrows to the combined submedian blotch; abdomen
finely, very closely punctate, the fifth ventral very broadly arcuate
at apex as usual but longer than in the preceding, a third longer
than the fourth; hind tibiae much more finely punctate. Length
(cf ) 10.0 mm.; width 2.7 mm. New Mexico (Jemez Springs).
conjuncta n. A
sp.
Prothorax more coarsely punctate and a little more abbreviated,
similarly well rounded at the sides. Male elytra with the inner
of the subbasal spots much smaller than the outer, the very large
blotches formed by the confluent submedian and subapical spots
