SYNONYMY. 

 Fam, CocHLiDioNiD^, Grote, ex Hiibner 1806. 

 = Cochlidia, Hiibn., 1806. 

 -- Cochlidice, Hiibn., 18 16. 

 = Limacodidce, Auct., post 1825. 

 = Eucleidce, Dyar, 1894. 

 = Apodidce, Grote, 1895. 

 = Heterogeneidce^ Meyrick, 1895. 

 Family type : Cochlidion avellana (testudo). 

 Gen. Cochlidion, Hiibner, 1806. 

 = Apoda, Haworth, 1809. 

 = Limacodes, Latreille, 1B25. 



The above synonymy is proposed as being more correct than the 

 terms employed for the group in current literature. The first plural term 

 is employed by Hiibner and should be retained. I cannot find that 

 Cochlidion is preoccupied. In any event the correct generic title of the 

 type should be used to form the family name.
