On the genus Cerobates Schh. and sescription of some new species

The genus Cerobates Schh., widely spread in the oriental, australian and ethiopical regions, is chiefly characterized by having the anterior tibiae notched and strongly toothed on the inner edge, and by having the antennae filiform, not clubshaped; these two characters distinguish it respectively from Trachelizus Schh. and Stereodermus Lac. In Lacordaire’s classification of the Brenthidae ¹) Cerobates belongs to the group Trachelizides, but in the new arrangement recently proposed by Prof. Sharp in the Biologia Centrali Americana ²), the Trachelizides are divided into two groups: Stereodermina and Trachelizina. In the former, Stereodermus, which has the anterior tibiae more or less notched and the hind coxae more than usually distant from one another, is considered as the typical genus of the group, whilst, in the latter, the typical genus Trachelizus has the anterior tibiae unnotched and the hind coxae separated by only the width usual in the Brenthidae. Cerobates should be placed in the Stereodermina.
