Anomccm, belong to the Carabida; ; six belong to the Pime- 

 lidiB, viz. Adesmia, Diesia, Platyope^ Ocncra, licdyphancs and 

 Tagona ; one to the Helopidte, viz. Ditylus; and two, viz. Pe- 

 dilus, and Pogonoccnis, to the Pyrochroidas. Except Caris, 

 which is Brazilian, and appears to have been previously named 

 Ctenostoma b}' King, all the above genera are Russian, toge- 

 ther with several more, which are indicated by our author in 

 his catalogue of genera, and which wll no doubt hereafter be 

 described and figured by him. 



Among the insects most worthy of remark, is the Carahus 

 baccJiivorus, an Oonalaschka insect, which, when its proper 

 prey is deficient, and its carnivorous appetite cannot be satis- 

 fied, subsists on the berries of the Empetnim 7iigrum, or crow- 

 berries. There is also a species of that singular genus Blaps 

 [Blaps hcdophila), which, carrying the propensity of the Pime- 

 lidae to the extreme, inhabits the salt crust which is formed by 

 the Lake Indus. The Lethnis Lo7igimaniis is also a remark- 

 able insect, from its approaching much nearer to the Lampri- 

 midtv than the species common in English collections. Of this 

 last genus, there are no less than four species described ; and 

 of the economy of the common Lethnis Cephalotes an account 

 is given ; which, as it seems a fair example of the skill of the 

 author as an entomological observer, we shall here abstract. 



" Le Lethrus cephalote est un animal tres nuisible aux en- 

 droits cultives, parce qu'il cherche de preference les gemmes 

 ou les feuilles a peine apparentes et les coupe nettement avec 

 les pinces tranchantes de ses mandibules. C'est pourquoi on 

 I'appelle en Hongrie, ou il fait beaucoup de mal aux vignes, 

 coujieur, ScJineidei- ; la poitrine avancant beaucoup au-dessous 

 de I'abdomen, les pattes de derriere paraissent inserees pres 

 de Tanus. II grimpe tres-bien, et fait son chemin de retour 

 en reculant. Apres avoir coupe le coeur d'une plante, il re- 

 cule comme une ecrevisse, portant sa proie dans son trou. 

 Chaque trou creuse dans la terre est occupe par paire. Mais 

 du tems de I'accouplement, il se montre souvent un male 

 etranger qui desire d'y etre admis. La se livre un combat 

 vehement, qui est toujours nourri par la femelle, laquelle, fei- 

 mant I'entrce du trou, pousse toujours le male du derriere. 

 Ce combat ne cesse qu'avec la mort ou la fuite du male 

 etranger."
