Differs from others of the genus in its narrow, attenuated, and obliquely strigose 
elytra. 
COLON. 
Colon, Herbst, Kafer, vii. p. 224 (1797). 
Body generally ovate or oval, convex, and densely pubescent. Mead moderate, sessile, without any occipital 
ridge. . Thorax sometimes large, widest at or near the base. lytra rather long, entire. Antenne 
generally short; 11-jointed, 6-11 forming a gradually incrassated club. Palpi: mawillary with the third 
joint ovate, much incrassated, and the fourth joint slender, acicular. Prosternwm very small; episterna 
indistinct, apparentiy small ; epimera small, inflexed beneath the coxal cavities ; coxal cavities moderate, 
rounded, open behind. Mesosternum carinated ; episterna large, triangular, extending to the coxal 
cavities ; epimera humeral, large and long, extending to the coxal cavities; coxal cavities separated by the 
carina. Metasternum moderate, not reaching the sides of the body ; episterna large and long, extending 
beyond the cox; epimera very narrow, wholly covered by the epipleural folds of the elytra; coxe 
contingent, not reaching the sides of the body. Venter with the segments variable in number, generally 
four or five. Legs moderate, usually robust; tibiz spinose; femora sometimes armed with incurved teeth 
on the inner side; tarsi 5-jointed, the anterior pair generally dilated in the males. 
This is a genus containing numerous species, nearly all of which are of rare occurrence, 
in Europe and Temperate North America. One species is now known from Guatemala.

Body elongate-oval, convex, brown, clothed with rather long and dense pubescence, rugosely punctured. Head 
rather large, deflexed, the mouth slightly produced ; eyes large and rather prominent; antenne short, very 
robust, fuscous, gradually inerassated towards the apex. Thorax large, much longer and broader than 
the head, widest near the base ; sides rounded and margined: basal margin nearly straight, with the angles 
obtuse. Scutellum small, triangular, deeply punctured. Hlytra rather long, scarcely broader but twice 
longer than the head and thorax, widest near the shoulders, with the punctures irregularly arranged in 
longitudinal rows; sutural stria rather deeply impressed, but not reaching to the scutellum; sides mar- 
gined; apex much rounded. Legs moderate, rufous-brown ; tibie slightly dilated, sparingly spinose, with 
one or more spurs on the inner side of the apex ; anterior tarsi dilated. Underparts rufous-brown.

One specimen. This species seems to be distinguished by its long and coarse 
pubescence, its rugose sculpture, and gradually clavate, short, antenne.
