Diseases and insects.—The diseases and insects to which the cultivated alliaceous plants are liable, if not numerous, are sufficiently destruc- tive. One of our greatest pests is The common onion-fly {Anthomyia ceparum, Bouche). It is thus described by Mr Curtis, one of our highest entomological authorities, in the " Gardeners' Chronicle," 1841:—"The male is of an ashy colour, roughish, with black bristles and hairs; the eyes are contiguous and reddish; the face silvery white; horns black; there are three obscure lines down the trunk, and a line of long blackish spots down the centre of the body, more or less visible in diiferent lights; the wings are transparent, slightly irridesoent, tinged with ochre at the base; the nervurespalebrown; poisersoohreous; legs ashy brown.
