Eemoval of the wild plants on which this kind of Aphis isto be found would probably materially lessen its Colliers or Black Flies are to be found in greatnumbers on the Curled Dock {liumex crisjms, whence theirname of rumicis), and also on Thistles; and it is stated(see Brit. Aphides, vol. ii. p. 83) that the wingless egg-producing female winters in Furze-bushes, the branches ofwhich may be found dotted with Aphis eggs. Beau Beetle.

The maggots are fleshy, wrinkled across, and with a smallhorny, rusty-coloured head. As far as I am aware, they arelegless, but in some kinds of Bruchi there are the rudimentsof feet on the front segments. The method of att
