 white-centred spot, and a white streak along the body. It feeds on the oleander 

 and the periwinkle from July to September. 



The locusts in the Mediterranean region are represented by the migratory 

 species (Pachytylus migratorius), which forms a common pest in south-western 

 Asia and north-western Africa, and appears in flocks so great as to darken the sun 

 for hours and strip off every vestige of vegetation. 



Among the Arachnida of the Mediterranean region are certain 

 representatives 01 the false spiders, a group common to the warmer 

 countries of both hemispheres. They live chiefly in deserts and steppes, and are 

 dreaded on account of their poisonous bite. One of the most noxious is Galeodes 

 araneoides, which inhabits Greece, southern Russia, Persia, and Arabia. It is 

 about 2 inches long, and pale yellow in colour, every part except the upper 

 surface being greyish brown. An allied Egyptian species, G. arabs, frequently 

 enters dwelling-houses, where it climbs on tables to catch flies ; and other species 

 have been observed to ascend trees. False spiders constitute the suborder Solifugce.
