MEMOIRS ON THE COLEOPTERA
Tribe PCECILOSOMINI.
Pyrodes Serv.
The following species is allied to marginatus White:
*Pyrodes cervicalis n. sp. Male moderately narrow and feebly convex,
densely sculptured and but feebly shining, obscure viridi-cupreous,
the elytra obscure green, frequently suffused with obscure cupreous, the
side margin narrowly and inconstantly brighter cupreous, the suture and
base never cupreous, concolorous; head much longer than wide, broadly
and very deeply furrowed, obsolescently and narrowly toward base;
tempora parallel, nearly straight, twice as long as the eyes and a little
less prominent; antennae a fourth longer than the body, slender, the third
joint almost as long as the next two combined, obsoletely and not densely
sculptured; prothorax, excluding the spine, slightly less than twice as
wide as long, the truncate base and apex equal; sides sinuously diverging
from the apex to the apex of the very acute lateral spine, slightly behind
the middle, thence still more sinuous and converging to the base; surface
coarsely, confusedly punctate, broadly and feebly impressed medially;
scutellum moderate, as long as wide, pointed, finely and variably sculptured,
subglabrous, with a fine median stria; elytra three-fifths to threefourths
longer than wide, gradually narrowed from base to the obtusely
rounded apex, one-half wider than the prothorax, excluding the spines,
the surface even, densely, subvermicularly puncto-rugose; humeri widely
exposed at base and rather prominent; under surface cupreous, the
abdomen brighter and more polished. Female wanting. Length 23.5-
27.0 mm.; width 8.2-9.6 mm. Honduras. Four specimens.
Differs from marginatus in the absence of cupreous elytral mar-
gins, except very finely and inconstantly externally, and in the
cupreous under surface, among other characters. The fifth ventral
is shallowly but sharply sinuate medially at apex.
Subfamily CERAMBYCIN.E.
Tribe ASEMINI.
In this tribe and in some genera of the Callidiini as well, though
not so evidently in most of the latter, the second antennal joint is
remarkably developed in a relative sense, sometimes being not so
very notably shorter than the third; this is a highly distinctive
character in this part of the Cerambycinae, though reappearing in
some Clytids and several Lepturids, isolating the Asemini among
the other tribes in this vicinity. The genera are few in number
and not very strongly accentuated.
