Another work presented t Trustees is Poiteau's mag- 
nificent P ie Francaise. This comprises four large 
quarto volumes containing 431 plates, which were issued 
e 
separately, with text, at a franc and a half each, between 
and 1846. 
Pomona Britannica, of which Kew possesses a fine copy of the 
large edition, surpasses Poiteau in colouring, but does not equal 
it in drawing. 
Mexican Works on Botany, Materia Medica, &c. The Kew 
Library has received a valuable gift of books from the Secretaria 
de Fomento, Mexico. In 1787 an expedition was organized for the 
scientific exploration of Mexico and other parts of America under 
Spanish dominion, and Martin Sessé, a botanist, was nominated 
its leader. J. M. Mociño and V. Cervantes were associated with 
him in the botanical work ; and the two volumes entitled Plante 
Nove Hispanice and Flora Mexicana are from manuscripts left 
by Sessé and Mociño. Their interest now is little more than 
historical, as most of the specimens described as new have already 
been published by other botanists, and many of the identifications 
are obviously erroneous. A useful work is the Biblioteca Botanico- 
exicana, by Dr. N. León; it contains titles of works and 
Estudio are serial publications treating largely of medicinal 
plants. 
Moth Borers in Sugar Cane.—In the Kew Report, 1876, p. 26, 
mention is made of the ravages of the larva of a moth among the 
8 ana. It was identified as Phalena 
saccharalis of Fabricius, but regarded as the same as Diatrea
