CERAMBYCID.E 3 21
Tragidion Serv.
A very well defined genus, represented by numerous species in
the temperate regions of North America. The prothorax is larger
in the male than in the female and generally
clothed with thick
erect shaggy pubescence. The species known to me may be defined
briefly as follows:
Elytra corrugated
2
Elytra even, not corrugated, each with three very fine, unembossed,
thread-like lines, the prothorax in both sexes smaller than usual. .7
2 Prothorax sharply and prominently angulated or spinose at the sides;
elytral corrugation strong; antennae varicolored 3
Prothorax less narrowed, fuller at the sides and more rounded anteriorly
and with very small lateral tubercles 4
3 Body larger and stouter, black, the vestiture of the prothorax and
legs with pale bluish reflection; elytra fulvous-red, blackish at the
extreme base. Male with the antennae long and rather stout, the
joints, except the first two and last four, red, with swollen black
apices, the prothorax across the very acute post-median tubercles
as wide as the elytral base; anterior femora excavated at the lower
edge of the outer face from base to beyond the middle; punctures of
the subglabrous prosternum very coarse; elytra rapidly narrowed
from base to apex. Female with antennae much shorter than the
body, stout, broadly compressed, serrate apically, colored as in the
male but with the outer five joints black; prothorax with less prominent
tubercles and narrower than the elytra, the latter but very
feebly narrowed from the base; anterior femora simple, the prosternal
punctures very fine and dense, the bluish hairs long and dense.
Length (cf, 9) 28.0-31.0 mm.; width 8.5-9.5 mm - Lower California.
[T. annulatum Csy., nee Lee.] peninsulare Schaef.
Body nearly as large, velvety-black, first two joints of the antennae
black, the remaining joints fulvous, with their apices black, the
third and fourth joints very densely clothed at tip with black hairs;
prothorax strongly angulated at the sides behind the middle; elytra
fulvous, broadly black at base; cornuous processes between the antennae
more conspicuous than in coquus. Length 27.5 mm. Mexico
(Sonora)
annulatum Lee.
Body notably smaller and narrower, nearly as in peninsulare, except
that the thoracic and crural vestiture is deep black and not bluish
and that the elytral base is more extensively black. Female with
the antennae three-fourths as long as the body, rather slender and
not broadly flattened, deep black throughout; tibiae similarly com-
pressed, the legs, however, shorter and less stout; prosternum finely,
densely punctate posteriorly, transveisely rugulose anteriorly,
moderately pubescent; elytra perceptibly narrowed from the base;
lateral thoracic tubercles median and not post-median as in the two
preceding. Length (9) 21.0 mm.; width 6.3 mm. New Mexico
(Fort Wingate), Shufeldt. [fnlvipenne Csy., nee Say].
