increasing the pressure every day; they must remain till quite dry, 
supplying them with dry paper every day. The best way for drying 
Succulent and mucilaginous plants, such as Cactus, Epiphyllum, 
Cereus, Melocactus, &c. is with a hot smoothing-iron, the specimens 
placed between sheets of the blotting-paper, and ironed till they 
become sufficiently dry. 
When properly dried, the specimens should be arranged into ge¬ 
neral classes and orders, (which will be hereafter explained) and fas¬ 
tened in a book, provided for the purpose, with small slips of green 
paper; then at the base of the specimen, should be written down the 
name of the genus and species, its native country, time of introduc¬ 
tion, (it of foreign produce,) nature of the soil, colour of the flower, 
and time of flowering.

Most of the species of this family are very rich, resplendent, and 
beautiful in their colours, they are all timber-eating insects, and often 
prove very destructive from the long period they continue in a larva 
state. Marshman tells us in the Lin. Trans. X. that the grub of the 
B. splendens was ascertained to exist in the wood of a deal table, 
more than 20 years. The B. flavomaculata is very elegant, and far 
from being uncommon in sandy soils, where timber has begun to rot; 
its head enters within the thorax, and the Elytra (wing-cases) are 
each adorned with four, and occasionally five spots of a bright yel¬ 
low colour: the upper side of the abdomen is bright blue.
