Dicheros bicornis can reach a length of about in males, of about in females. Coloration and pattern of these beetles are variable, depending on subspecies. Pronotum may be dark brown or reddish, while elytra are usually yellowish or white, with brown markings on the apex or margins. This species shows a sexual dimorphism, as males are larger than females and have two horns (hence the Latin name bicornis) on clypeus. ==Distribution==
