INSECTS AFFECTING- THE CHINA TREE. 



The China tree {Melia azedarach) has always been considered as per- 

 fectly free from any insect attacks whatever. No cater{)illar of any 

 kind has ever been found feeding on its foliage ; no Buprestid or 

 Scolytid beetles bore in its trunk or branches, and no gall insects 

 disfigure its leaves or twigs. This tree, with its beautiful dense foliage, 

 is, iu fact, to be highly recommended as a shade tree in the South, and 

 especially in those cities which are so badly infested with the bag- 

 worm {Thyridopteryx ephemerceformis). This immunity enjoyed by the 

 China tree from the attacks of insects is not perfect, however, as we 

 have recently received from Alabama some twigs and leaves infested 

 with the scales of a Coccid belonging to the genus Lecanium ; but, 

 what is more interesting, tlie twigs are covered with the waxy scales 

 of a Ceroplastes of really beautiful appearance and new to science. 

 The leaf-cutting ant {Atta fervens) shows a decided partiality for the 

 leaves of this tree in Texas. (Riley.)
