A new contribution to our knowledge of the early stages of butteflies has come from Bombay, where Messers. Davidson and Aitken have published (Journ. Bomb. Nat. His. Soc., Vol 5,)half a dozen coloured plates, excellently drawn by Mrs. Blathwayt, representing the transformations of sixteen species. Their published notes, however, cover no less than 994 species and run through all the families, and among them will be found many interesting things,—a chrysalis of Elymnias “suspended by the tail only, but in a rigidly horizontal position,” a species of Abisara, one of the Lemoniinæ, whose larva has the head free, a gregarious Delias where the eggs are laid “in parallel rows with equal intervals,” a Papilio laying, like our species of Polygonia, ten eggs in a column, Hesperidæ with fluffy secretions and some where the transformations are open, and which in some cases have and in some have not a median girth.
