VERTICAL vs. HorizonTAL Insect Boxes.—A. Preudhomme de 
Borre has published a pamphlet on the “ Best arrangement of 
boxes and cartons of collections of insects.” While admitting 
that as far as space and convenience are concerned, the arrange- 
ment of boxes on their edges is advantageous, he claims that for 
the following reasons it is unwise, viz: (1) Specimens become 
loose and fall, breaking themselves and their neighbors; (2) or 
they turn on their pins with similar results ; (3) infected specimens 
are not readily detected by the dust.

4. The box for the preservation of specimens should be made of 
well seasoned pine, nine by fourteen inches and two inches deep, 
all outside measure. The lining of the bottom should be cork of

INsrcts AFFECTING THE CHINA TREE.—The China tree (Melia 
azedarach) has always been considered as perfectly free from any 
sect attacks whatever. No caterpillar of any kind has ever 
been found feeding on its foliage; no Buprestid or Scolytid bee- 
€s bore in its trunk or branches, and no gall-insects disfigure its 
leaves or twigs. This tree, with its beautiful dense foliage, 1s,

“specially in those cities which are so badly infested with the
