plumbeous hairs. Length 6.6-7.2 mm.; width 3.7-4.2 mm. Idaho
(Coeur d'Alene), \Vickham wickhami n. sp.
Form and general characters nearly as in u'ickhunii but larger and stouter,
still less evidently inflated posteriorly and much less so than in
kirbyi, deep black throughout, the under surface and legs not paler;
upper surface nearly as in wickhami throughout, except that there
is a notable admixture of fulvous hairs that do not appear in that
species, especially noticeable on the pronotum and toward the sides
and on the posterior slope of the elytra; vestiture throughout a
little longer and coarser than in -wickhami; under surface similarly
very densely and strongly sculptured throughout and with the
numerous short fulvo-cinereous hairs coarse and conspicuous;
punctures of the metasternum distinctly more isolated among themselves
than in the preceding species. Length 7.7 mm.; width 4.7
mm. British Columbia (Aldermere), communicated by Mr. Keen.
consuetus n. sp.
Most of the species proposed above seem to be very well defined
and not subject to much doubt, that is, if the limits of variability
disclosed in those few instances where it has been possible to study
series of specimens hold true for all. The longitudinal distance
separating the irregular transverse pale bands of the elytra is
rather variable as a rule, and whether those forms given in the table
as wholly unfasciate are constantly so or not cannot be conjectured,
though this would seem to be highly probable. Neglectus is without
much doubt a valid species, distinct from americanus, but my
single specimen is in very poor condition, being almost entirely
of americanus
denuded; possibly brunnescens may be a subspecies
rather than neglecttis. The transverse subposterior
lateral black
spot so characteristic of the posteriorly inflated kirbyi section, is
also evident in geminattis, and, besides the more developed pubes-
cence, this species is distinguishable from americanus, which it
otherwise much resembles, by the stronger and denser abdominal
sculpture. Egenus is a very aberrant species and it is unfortunate
that my only specimen, as in the case of Cytilus nigrans, should be
almost completely denuded and bald on the upper surface through-
out, as the pubescence would doubtless have a different type-form
from that prevailing elsewhere. Perditus, represented by two
mutually similar examples, is a peculiar species, having an unusually
small head; I have placed with it two other forms which evidently
differ, but which are rather too indefinite or too imperfect to
describe; one, unlabeled in the Levette cabinet, represented by two
