THA 



forth the perfect insect. Ahout the be- 

 ginning of August the males and females 

 may be found in pairs numerously on the 

 plants they frequent. They are of a dirty- 

 white colour, thickly dotted and clothed 

 with short hairs ; head broad and bluntly 

 triangular, with black lines down its 

 centre and sides ; eyes, one on each side, 

 near the base of the head ; rostrum long, 

 bent underneath its body when not in 

 use; antennae ending in a fine bristle; 

 thorax and shield (scutellum), adjoining 

 the back of the head, brownish. The 

 wing-cases are brown, mottled with ochre, 

 with four whitish patches on the margin 

 the under wings are transparent am' 

 irridescent. The legs, six in number 

 short, but two hind-legs longest, and 

 formed for leaping. So effectual are 

 they for the purpose, that, as Mr. Kirby 

 states, after showing their mode of leap 

 ing, they will spring five or six feet at a 

 time, being more than 250 times their 

 own length, or "as if a man of ordinary 

 height should be able to vault through 

 the air to the distance of a quarter of a 

 mile." It is not ascertained where the 

 eggs of this insect are deposited, but 

 probably on the stems of the plants on 

 the shoots of which the larva feeds. It 

 appears, however, that they oaa travel 

 after hatching, for seedlings and plants 

 raised from root-cuttings are often afijcted. 

 We know of no better plan for destroying 

 the insect than drawing the affected 

 shoots between the fingers, and then 

 dipping these into a bowl of water after 

 each grasp. In the case of carnation 

 stems and other flowers, requiring more 

 tender treatment, all the froth may be 

 taken from the insect by means of a piece 

 of sponge, and itself then removed by a 

 camel's hair brush.

Annuals, seed* in tfc open ground in April; 

 pereiiniais, by seeds and division ; shrubs, by cut- 

 tings in sandr soil, under a bell-glass, in. spring, 

 and a band-light in summer. Most of them in the 

 atmosphere of London, and farther north, require 

 a cold pit or a greenhou-e in winter. In dry 

 places in the south of England they will frequently 

 stand our winters uninjured. They are not a,t all 

 particular as to soil.
