third genus, ^rchon, is formed from the same family, its type, a 

 new species under the name of yl. emarginatus, being described 

 in conjunction with it. Cetonia has also furnished materials for 

 the formation of three genera ; 1. Genuchus, the type of which is 

 the Cetonia cruenta^ Oliv. ; 2. Schizorhina, type C. atropunctala, 

 Kirby, Lin. Tr. xii. ; and 3. Gnathocera, the Cetonia vitticollis of 

 Latreille's MSS. being its type. This insect is described by Mr. 

 Kiiby, together Avith another species, G. immaculata. The re- 

 maining species described are the Onthophagus cervicornis, and 

 O.Aries; and a new species ol Mimela^ M. nigricans. We regret 

 that the necessity of restraining our notice from farther exceeding 

 the limits to which it should be confined, compels us to omit the 

 discriminating characters developed in this very valuable paper, 

 from the promised continuation of which we anticipate much im- 

 portant additional information. 



British Entomology ; or Illustrations and Descriptions of the 

 Genera of Insects, Sfc. By John Cuktis, F.L.S. Nos. xvii and 

 xviii. 



The first of these numbers comprises, 1. Agrjlus Chryseis, a 

 species new to Britain, discovered in the New Forest, and be- 

 longing to a genus of Buprestidce recently established by Megerle, 

 of which the Buprestis viridis may be taken as the type ; 2. 

 Arctia conosa, Hiibn., also new to Britain, and only taken hitherto 

 at Whittlesea Mere ; 3. Bracon Denigrator, the male of which 

 is now for the first time figured ; and 4. Microdon apijormis, the 

 Mulio apiarius, Fab., and Aphriiis auro-pubescens, Lat. 



The second contains, 1. Necrophorus Germanicus, extremely 

 rare as British, under which Mr. Curtis has given a synopsis of 

 the species discovered in this country, a plan well adapted to 

 render his work still more valuablo to the collector; 2. Thya- 

 tira Batis, the Peach - blossom of the Collectors; 3, Bassus 

 Calculator ; and 4. Cydnus duMus, a genus established by Fabri- 

 cius, but subsequently reduced by Latreille to the rank of a divi- 

 sion of his Pentatoma.
