Genus Homorocoryphus Karny. 



Homorocoryphus Karny, Revis. Conocephalid., pp. 4, 41 (1907). 

 Conocephalus aucl. (in part). 



Conocephahis Redtenbacher, Mon. Conoceph. (Species 73-101), pp. 70-72, 103- 

 115 (1891). 



The species of the present genus have the same general appearance 

 as those belonging to Neoconocephalns, but can at once be recognized 

 by the contact of the fastigium of the front with the base of the 

 fastigium of the vertex.
