The elytral pubescence is semi-erect and very short,but is quite distinct when viewed from the sides. On each ofthe front tibiae the apical spur is much larger than the freespur, but on the others the free spur is the more conspicuous 343 of the two, and the second and third joints of the tarsi arestrongly dilated. basiflava, n. black; front of head, antennae, base of elytra, andparts of front and middle legs flavous, hind legs black, theknees all more or less pale.
