Type.—Megilla labiata Fapricrus, 1804. (By designation of Westwood, An 
introduction to the modern classification of insects, vol. 2, Synopsis of the 
genera of British insects, p. 158, 1840.) Apis acervorum Linnaeus, 1758, 
designated by Richards, Trans. Roy. Ent. Soc. London, vol. 83, p. 172, 1935. 
Isogenotypic with Macropis Panzer. 
Richards, The generic names of British insects, pt. 5, p. 91, 1987, has pro- 
posed that Apis acervorum Linnaeus be considered the type of Megilla and 
that Westwood’s earlier designation be rejected. Megilla would then fall 
as a synonym of Anthophora Latreille, if that name is placed on the 
Official List of Generic Names, otherwise under Podalirius Latreille.
