genera: 
Dikelocephalus Owen, 1852. 
Referring to the restricted genus the following species: 
Dikelocephalus minnesotensis Owen, and a variation D, dalyi n. sp. The palpebral 
lobe of D. dalyi is shorter than in typical Dikelocephalus, in this respect, resembling 
some species of Anomocare, but not the typical, species Anomocare laeve Angelin, D. 
Texanus n. sp. 
Dikelocephalus hartti Walcott. This is the Conocephalutes hartti Walc., 1879.
