272 SYSTEMATIC ARRANGEMENT. 



founded with Pentatoma, till Lamark effected the 

 separation. The peculiarity which has occasioned 

 this separation, is necessarily accompanied with some 

 others which render them very distinct. As the 

 scutellum is placed over the wings, it must be suffi- 

 ciently elevated not to prevent their movements, and 

 this gives the body a much more convex and rounded 

 appearance than among the other tribes, sometimeSj 

 indeed, it seems quite gibbous. They invariably 

 live on plants, extracting the juices from the more 

 tender parts, where they are able to introduce theii 

 sucker. No example of the genus occurs in Britain, 

 and, indeed, very few inhabit any part of Europe, 

 S. lineata, however, a small species of a deep red 

 colour marked with longitudinal black streaks is 

 plentiful on umbelliferous plants in the south oi 

 France, and along the northern shores of the Medi- 

 terranean. The greater proportion of those described 

 in entomological works are from Java, China, East 

 Indies., Cape of Good Hope, and Surinam. Most oi 

 these are very splendidly coloured insects, decoratec 

 with the deepest tints, and having a fine metallic 

 gloss of golden-green, copper, or silver. The indi- 

 vidual figured belongs to Serville's second subdivision 

 that in which there is no abdominal plate ; the thoras 

 with a lateral spine ; the body long, and narrowing 

 gradually to the hinder extremity. The colour i 

 deep orange yellow, with several black spots, sur- 

 rounded with light yellow, scattered over the surface 

 but the colour and markings are very variable, 

 is a native of China and Japan.
