NOTE XXXI. 



ON THE GENUS CEROBATES SCHH. 

 AND DESCRIPTION OF SOME NEW SPECIES 



Dr. ANGELO SENNA, 



Assistant in the R. Museum at Florence. 



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 respec- 

 tively from Trachelizus Schh. and Stereodermus Lac. 



In Lacordaire's classification of the Brenthidae ') Cero- 

 bates belongs to the group Trachelizides, but in the 

 new arrangement recently proposed by Prof. Sharp in the 

 Biologia Centrali Americana^), the Trachelizides are 

 divided into two groups : Stereodermina and T r a- 

 chelizina. 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 un- 

 notched and the hind coxae separated by only the width 

 usual in the Brenthidae. Cerobates should be placed in the 

 Stereodermina. 



Lacordaire's group of the Ephebocerides (not» tribe" 

 as Prof. Sharp writes) is correctly suppressed being a group
