are peculiar to the truly southern countries. The domain of 

 the latter is recognized by the appearance of certain species 

 of Cigala mantes^ termes, <SfC., but especially by the pre- 

 sence of the European scorpion, and the ateuchus sacer. 

 The culture of the olive — the spontaneous growth of the 

 arbutus, speak still more sensibly to the observation. This 

 change becomes extremely remarkable on proceeding from 

 Paris to Marseilles, about the territory of Montelimart. The 

 shores of the Mediterranean are something warmer ; there we 

 find the MygalcB, the Cebriones, the Onitis, the Scarites, SfC. 

 appearing for the first time. If we pursue our way into 

 Spain, and visit the beautiful districts of the eastern part of 

 that country, where the orange and the palm-tree flourish in 

 the open plains, we are saluted by a new order of arachnida 

 and insects, intermingled with some already observed in the 

 south of France. We find there nemoptera, and various 

 other insects analogous to those of Barbary and the Levant, 

 Having examined these species, the entomology of the Atlan- 

 tic countries of Africa, or of those which are situated on the 

 Mediterranean, as far as Atlas, will not occasion much sur- 

 prise. There we also discover certain genera of insects 

 which are peculiarly predominant in the countries comprised 

 between the tropics, such as the graphiptera, S^c. 



Respecting the insects of the south-east of Europe, our 

 knowledge is yet somewhat imperfect. It may, however, be 

 observed, that the papilio chrysippus of Linnaeus, which is 

 common in Egypt and the East Indies, is also found in the 

 kingdom of Naples. Most of the Egyptian species are 

 strangers to Europe. Its southern extremity, bordering on 

 Nubia, presents several individuals of the Midas, which 

 like the hucephalus antenor, and gigas, inhabit only the 

 hottest climates of the old continent approximating to the 

 equinoctial line. From the banks of the Senegal and on- 

 ward, in the interior countries more to the south, we no
