MEMOIRS ON THE COLEOPTERA
strongly punctate and glabrous; prothorax larger than in obliteratus
and more tubulate at base, as wide as the elytra or very nearly, the
apical and basal margins finely yellow, the apical band angularly
emarginate and almost divided at the middle; sculpture very fine
and densely punctato-rugulose throughout; elytra slightly more
than twice as long as wide, the posterior half of the scutellum and
adjoining lateral small spot, a broad oblique discal spot behind the
base, a broad sinuate fascia as before described near basal two-fifths,
a feebly oblique and entire narrower fascia near apical third and the
apex, rather broadly, yellow; abdomen with the yellow annuli much
wider than in obliteratus. Male rather more slender and cylindric,
with a still larger and more medially tumid prothorax, pale redbrown
in color throughout, the frontal tumidity similar, the prothorax
wider than the elytra, less arcuate or nearly straight in median
third at the sides and not at all tubulate at base, the surface still
more finely sculptured and densely opaque, the pale apical margin
very fine, the basal wanting, the vestiture consisting of minute,
sparse and very inconspicuous hairs; elytra with only the oblique
post-basal, post-median and apical spots and bands and these reduced;
abdomen uniformly, closely pubescent, without condensed
pale annuli. Length (cf, 9) 15.0-16.0 mm.; width 4.4-5.0 mm.
California (locality unrecorded) insignis Lee.
Form nearly as in the preceding but a little smaller and notably more
slender, the red-brown color slightly more obscure in the male,
which has very much more suffused vestiture than in insignis,
sometimes almost completely obliterating the spots and fasciae;
front and triangular opaque spots nearly similar; prothorax nearly
similar in form and sculpture, even more tumid medially between
the more foveiform depressions just before the middle near outer
fourth, the short decumbent pubescence coarser, paler and closer;
elytra much narrower and somewhat less convex than in insignis,
with the same spots and fasciae as in the female of that species though
much reduced, the post-basal fascia but seldom wanting, the general
vestiture more or less dense and yellow and not rather sparse, fulvous
and less visible as it is in insignis; under surface wholly immaculate,
densely clothed with yellowish-tawny pubescence. Length (cf)
14.0-16.0 mm.; width 4.0-4.6 mm. California (Hoopa Valley,
Humboldt Co.) incongruens n. sp.
4 Form throughout as in insignis, the female having nearly similar
coloration, the elytra more deeply black; frontal carinae fine but more
sharply defined, the surface between them more concave; prothorax
of similar form and vestiture, and likewise but very little wider than
long, except that it has the apical yellow band, not angularly
emarginate, but broadly and gently sinuate medially and the fine
subvermicularly rugulose sculpture a little coarser medially; elytra
but slightly wider than the prothorax, otherwise nearly as in insignis,
except as above stated and in having the space between the
post-median and apical yellow fasciae less extended; apices similarly
obliquely arcuato-truncate, with the angle very obtuse and narrowly
