Allied to Taphrocranum Horv., but the head is somewhat differ- 

 ently structured and sculptured, the eyes are not stylated, the 

 rostrum is longer and the structure of the abdomen is différent. In 

 his description of Taphrocranum Horvath says : « vertice ante 

 ocellos sulco mediano distincto instructo ». Breddin in his descrip- 

 tion of the typical species, T. robustum Bredd., says . « zwischen 

 ihnen [the ocelli] eine schmale Làngsfurche, die hinten in einem 

 starken Punkteindruck endigt». Neither is the case in Molybditis, 

 where the furrow is between the ocelli but of the same depth and 

 breadth throughout and scarcely extending beyond a line uniting 

 the anterior ends of the rather large ocelli.
