140 Anali/tical Notices of Books, 



tiiiguished author. 4. Laphria nigra^ the only species of this 

 numerous genus of Diptera which has yet been detected in Eng- 

 land, where it is by no means common. 



The twenty-fourth number comprises 1. Hydaticus cinereus^ 

 recently captured for the first time in this country by Messrs. 

 Chant and Bentley. It is the Dytiscus cinereus of Linne, but not 

 of Fabricius nor of Marsham. 2. Vanessa Antiope^ with its larva, 

 3. Zarcea fasdata of Leach. 4. Merodon clavipes^ of which only 

 two specimens have been taken in England. 



An additional leaf is given in the last number for the purpose 

 of being substituted for that containing the description of Acilius 

 cinereus^ the insect previously figured under this name being in 

 fact a new species, to uhich Mr. Curtis has found it necessary 

 to assign the name A, caliginosus. 



In concluding our notices of the second volume of this import- 

 ant addition to our entomological libraries, we need only refer to 

 our previously expressed opinions of the value of the work, and of 

 the beauty and accuracy of the figures contained in it, and repeat 

 our cordial wishes for its continuance in the same excellent style 

 as that in which it has commenced. A third volume has since 

 been completed, to which we shall advert in our next number.

In the present numbers of this valuable addition to the Natural 

 History of the Mammalia^ there is less than the usual proportion 

 of novelty. The most striking feature exhibited by them is the 

 dismemberment of the genus Elephas, for the purpose of esta- 

 blishing a new one under the name of Loxodonta. It is some- 

 what singular that notwithstanding the very striking difference 

 in form between the African and the Asiatic Elephants they 

 should have been confounded together by Linne under the deno- 

 mination of Elephas maximus, M. G. Cuvier first pointed out.
