DILO-BA CJERU LEO-CE'PHALA. Figure-of-Eight 

 Moth or Blue-head Caterpillar. The eggs of this moth 

 are laid on the stems and branches of Apple and Plum 

 trees in September, and the caterpillars hatch out when 

 the trees are coming into leaf. They are green or smoky 

 green, with a small blue head. They feed on the leaves, 

 and are full grown about the middle of June. Being of 

 large size they may be shaken from the trees and de- 

 stroyed. The moths may also be caught by means of a 

 lamp at night during November, the lamp having a 

 temporary roof of tarred boards placed over it. 



DIMA CRIA. (One of seventeen sections into which 

 the genus Pelargonium has been split. From dis, twice, 

 and makros, long ; referring to the two lower stamens 

 being twice the length of the other three. Nat. ord. 

 Geraniaceae.) (Hoarea is now the accepted name of the 

 section.) 



There are about twenty species included under this 

 head, all little botanical things, with fleshy or tuberous 

 roots. Generally they are grown in sandy peat ; they 

 live much longer, however, confined in small pots in 

 equal quantities of peat, loam, and pounded brick, well 

 drained.

_ Annual or shrubby perennials, requiring the protec-

 sown in heat and planted out in May, or sown in the open 

 border in April. The perennials by cuttings in heat, 

 when sufficiently strong young shoots are obtainable in 

 spring. Fibrous loam, a little leaf-mould and sand.

 the names of Venus. Nat. ord. Sundews [Droseraces]. 

 Linn. iQ-Decandria, i-Monogynia.) 



Notwithstanding all the fables about this plant, it is 

 one of extreme interest to cultivators, owing as much to 

 the care and skill necessary for its management, as to 

 the irritability displayed by the three bristles on the 

 blade of the leaves. They are so situated that an insect 

 cannot pass along, or alight on the part, without touching 

 one of them, when they suddenly fold, like the fingers of 

 the two hands clasped together, and enclose the insect 

 with a firmness beyond its strength to escape. Green- 

 house evergreen. Division of the plant ; seeds at 

 times ; leaves laid in damp moss, under a glass, will 

 sometimes emit a young plant at its margin ; peat earth, 

 with a little sphagnum, moss, and bits of potsherds 

 broken small. The pot is set in a pan, stuffed round, 

 not very tight, with clear moss, and the pan filled with 

 water ; a bell-glass is placed over the plant, but kept 

 from going close down all round. Summer temp., 60 

 to 85 ; winter, 50 to 60.

 of each scale ; otherwise from seeds being borne in twos. 

 Nat. ord. Cycads [Cycadaceae]. Linn. 22-Dicecia, n- 

 Dodecandria. Allied to Cycas revoluta.) 



A fine Palm-like plant. The fruit of this Dioon, 

 which is as large as a chestnut, is powdered by the natives, 

 and formed into a kind of arrowroot. Supposed to be 

 propagated by suckers, and seeds when obtainable ; 

 rough, sandy loam, with some broken bricks and char- 

 coal. Summer temp., 60 to 90 ; winter, 55 to 60.
