Desmiphora is distinguished from the neighbouring genera by 
the numerous tufts of hair ar ising from the thorax and elytra, 
and the long hairy clothing of its body and limbs. The body is 
elongate-oblong or linear, “with the apex of the elytra obtusely 
rounded. The head is small and retracted, with sloping crown 
very short face and muzzle, and large eyes. The antenne: 
are stout, about as long as the body, tapering to a point, 
with short thick basal joint narrowed at the base, elongated 
second and third joints, and progressively abbreviated remaining 
jomts. The thorax has an acute prominent tubercle on each 
side in the middle. The legs are stout, thighs not clavate ; tarsi 
with short triangular joints, and fine divergent claws.
