MEMOIRS ON THE COLEOPTERA
the apex feebly lobed from a vertical viewpoint; sterna coarsely
but not densely cribrate, the abdomen much more finely, rather
sparsely punctate, more coarsely at the middle of the first segment
and with a very dense patch at each side of the second segment.
Length 7.7 mm.; width 4.9 mm. Idaho (Cceur d'Alene), Wickham.

lecontei Wickh.
Prof. Wickham very kindly consented to part with one of the
only two known examples of this species, and it now rests in my
collection as one of its most valued specimens.
Tribe SIMPLOCARIINI.
Comparatively few species, widely distributed over the higher
latitudes of the northern hemisphere, are sufficiently isolated in
structure to require a separate group or tribe under the above name.
They differ widely from the Byrrhini in their shining and sparsely
sculptured integuments, less closely retractile legs and peculiar
system of elytral striation; from the preceding tribe they differ in
possessing true elytral striae. There are two genera as follows:
Posterior femora in repose resting under and against the hind coxae
throughout, the coxae extending to the sides of the body, the epipleura
narrow anteriorly, gradually disappearing at the usual point
opposite the hind coxae; antenna? gradually enlarged and compressed
distally through about the last five joints as in the preceding tribe.
[Type 5. metallica Sturm]. Palaearctic and nearctic. . . Simplocaria
Posterior femora in repose resting against both the hind coxae and the
obliquely truncated posterior end of the anterior part of the epipleura,
the latter much wider than in Simplocaria, the hind coxae
not attaining the sides of the body; antennae with an abrupt 3-jointed
club. [Type S. carpathica Hampe]. Palaearctic *Trinaria
Trinaria Muls., is represented at present by the type species
only; there are some forms of true Simplocaria, such as acuminata
Erichs., that imitate it very closely in outward form and especially
in the nearly glabrous integuments and sharply acuminate tip
of the elytra, but the epipleura and hind coxae, as well apparently
as the antenna?, do not depart from the normal type of Simplocaria,
where the scutellum throughout is better developed than in Tri-
naria; the latter should therefore be considered a distinct genus and
not a subgenus of Simplocaria, where it now rests in the latest
European catalogue.
