lies close under the ribs, or roves about 

 in search of a mate (Curtis). Flowers 

 of sulphur have been recommended as 

 destructive of this plague, but we believe 

 that Scotch snuff, applied by means of a 

 dredging -'box (perhaps Brown's Fumi- 

 gator would answer), is as effectual an 

 application as any. Prevention, however, 

 is better than cure; and if the plants are 

 kept healthy by due ventilation, and by 

 moisture both in the air and soil, this 

 insect may be usually banished. 



T. ochraceus infests the ripe fruit of 

 plums, peaches, and nectarines, piercing 

 the stalks, and causing their fall, and ren- 

 dering the fruit disgusting. It was first 

 noticed and described by Mr. Curtis. It 

 is narrow and linear, of a bright and deep 

 ochreous colour, the eyes are black, the 

 liorns appear to be only six jointed and 

 "brownish at the tips, it has three ocelli 

 in the crown, the body is hairy, the tip 

 pointed and bristly, the wings are shorter 

 than the body in the male, lying parallel 

 on the back when at rest, narrow, espe- 

 cially the under ones, and fringed, the 

 liairs longest beneath and at the point, 

 tips of feet dusky. It is destroyed by the 

 same means as T. Adonidum. 



THROATWORT. Oarripa'nula cervicn'ria, 

 Campanula trache'li urn, and Trnche'linm. 



THRYA'LLIS. A synonyme of Galphi- 

 mia. The following should be added to 

 to that genus : 



O. brachystu'chys (short-spiked). 4. August. Rio 

 Janeiro. 1823. 



THU'JA. Arbor Vitse. (From thy on, a 

 sacrifice ; the resin used as incense in 

 eastern sacrifices. Nat. ord., Conifers 

 [Pinacese]. Linn., 21-Mona:cia 10-Dtcan- 

 drifi.) 



Hardy evergreen trees. Seeds, which ripen 

 freely, or by cuttines; the seeds are best sown in 

 April, slightly covered, and if a frame or hand- 

 light can be set over them, all the better ; moist 

 soil suits most of them ; a few of the tenderest 

 will require protection until they become some 

 size.

THUNBE'RGIA. (Named after C. TV 

 Thunberg, the celebrated botanist. Nat 

 ord., Acanthads [Acantbaceae]. Linn., 



Stove evergreen climbers. Seeds in early spring, 

 in a strong, moist, sweet hotbed ; cuttings, any 

 time before the end of August, in sandy soil, 

 under a bell-glass; fibry loam and peat, with a 

 little rotten dung and lime-rubbish Winter temp., 

 48 to 60; summer, 60 to 80. As they are very 

 subject to red spider, perhaps the best mode of 

 treating these fine plants is to grow them a* an- 

 nuals, throwing the plants away in the end of 

 autumn. If preserved, the flowers of sulphur and 

 the syringe must hardly ever have a holiday. In- 

 deed. the syringe and a little shade are necessary 

 to their health in summer.
