Plattvea fittoni was named and badly figured by Brodie 

 (Fossil Ins. 1)1. iii. fig. 9, 1815) from a specimen in the 

 13ritish Museum from the English Purbeck rocks. In 185<) 

 Giebel (Ins. d. Vorwelt, p. 20U) proposed the generic name 

 Adonia for Brodie's figure. This name haviiij; been previously 

 used, Handlirsch (Fossil Ins. p. 629, 19U6) proposed to 

 replace it by Pseudadoida. Later, Johannsen (' Genera 

 Insectorum,' Mycetophilidas, p. 81:, 1908), still without 

 examining the tyjie-specimen, placed Adonia and Pseudadonia 

 as synonyms as Mycetopliilites, Forster, an Oligocene genus 

 for which no type-species has been named.
