Notes on the genus Lichas. 



Quart. Jour. Ceol. Soc. London, vol. 58, 1902. p. 50. 



The author classifies tlie Lichadiclae into two groups as follows: 



Group 1 — Protolichas: 



Sec. A. Corydocephalus type /.. plamtilm Barr. 



— B. Dicranopeltis type L. scaber Bevr. 



— C. Platylichas type L. margaritifer Nieszk. 



— D. Metopolichas type /.. verncosus Eichw. 



— E. Metalichas type /.. r'lcatricosux Schm. 



— F. Uraliclias type L. Ribcirol Delsj. 



— (). Ceratarges type /.. arnuitus (Joldf. 



— H. Oncholichas type /.. orniitus. 

 Group 2 — Deuterolichas: 



Sec. A. Hopolichas type L. triruspidatus Be\ i . 



— B. Homolichas type /-. tingiistus Beyr. 



— C. Conojichas type L. aerjuilobn Steinh. 



— D. Echinolichas type L. Eriopis Hall. 



— E. Leiolichas type L. illaenoides Nieszlc. 



— F. Paralichas type I., dalccarlicus Ang. 



— Ci. Terataspis type L. grandis Hall. 



— H. Ceratolichas type L. gryps Hall. 

 The classification is based on (1st) a group with a pair of bi-composite lateral 

 lobes to the glabella, and a more or less definite fourth pair of lateral lobes; (2nd) a 

 group with a pair of tri-cornposite lateral lobes, originating b\- the fusion of the 

 fourth pair, witii. the bi-composite pair of the preceding group.

The author remarks (on p. 196) : "It seems open to question, whether the European 

 species of Bracii\nietopus should not be regarded as constituting a distinct group or 

 subgenus, for which the name Bracliymetopina may be suggested."
