23. Catalogus Hymenopterorum, . . . vol. x, C. G. de Dalla Torre, 

 Leipzig, 1896. — This part deals with the bees united under the head 

 Apidae. Workers will probably be surprised to see Andrena changed to 

 Atilhrena; Nomia and Eunomia united as one genus; and the synony- 

 mizing of Diadasia, Emphor, Melissodes, Synhalonia, Tetralonia and 

 Xenoglossa with Eucera. Podalirius is to replace Anthophora, Entech- 

 7iia, Clisodon and Habropoda, the three latter, however, being regarded 

 as subgenera. Bombomelecta is regarded as a synonym of Melecta. 

 Heriades is spelled Eriades, and includes Chelostoina. Too much faith 

 cannot be placed in the localities given for some of the species inasmuch 

 as Epeolus rufoclypeus, said to come from Cuba, and Megachile niartiti- 

 dalei, multidens &nApedaH3, said to come from Indiana, were all described 

 from Jamaica, West Indies ! Armnobates is to replace Phileremus, the 

 latter being a synonym of the former. While much of this uniting of 

 genera is no doubt justified, yet we venture to predict that many of the 

 so-called synonyms will yet stand as distinct genera. The work is quite 

 voluminous, including 643 pages, and brings the list of species and bib- 

 liography down to the end of 1893. — F.
