The species belonging to our fauna are small and elongate, with the elytra only a little wider than the They ditier from the typical species of tropical America by the femora being not armed with a tooth. We have seen already in many genera that this character is quite unim- portant, and I consider it unworthy of even suiigeneric distinction. Our si)ecies nuiy be thus tabulated: Second joint of funicle hmjjer than third S. " not " " 10. 3. Front moderately narrow 8. â ⢠very narrow, linear 0. 8. Mottling of upi)er surface not very distinct 4. " " very conspicuous 6. 4. Larger, less densely clothed with scales 1. operculatua. Smaller, more " " " " 2. nanulus. T).
