together different, they are the most voracious creatures I ever saw; 
they eat so much that the skin bursts every second dav; they also kill 
each other when in the same box although well provided with food. 
Therefore having obtained larvee of S:/pha in the manner indicated 
above, separate them as early as possible, keeping each individual in a 
separate small box and feeding them with small pieces of fresh meat, as 
much as they may devour in one day. Feeding the following day, be 
careful to remove the remnants of the repast of the day before. Just as 
with negro children the larvee of Sz/pha when very young and after each 
moult appear snowy-white, after an hour they are steel blue and after an- 
other hour genuine darkeys ; jet black. 
Woodboring larvae. For the greater part Lamellcornia. Longicornia, 
Elateridae, Buprestidae, Curculionidae — are easy to raise, but care 
has to be taken that only specimens of the same species are confined to 
one box, 
It is necessary to give them larger boxes, so that large pieces of 
wood may be enclosed, but it is very difficult to observe the proceed- 
ings except with very large species. These may be treated as follows : 
Take a piece of wood 4 inches cubic, split it at middle and then make at 
the interior sides a cavity just large enough that the larve may easily 
move, then fasten the parts together with a strong 1ubber band. Moisten 
the wood in the box a little twice a week and if the larva escapes by 
boring a hole through the wood, replace it at the central cavity filling the 
borehole by a bung. 
Some larvze especially Lamelhvornia and Llateridae before trans- 
formation enter into the earth, For such species place some earth in the 
box, but not before the larvae show a decided wish to go there by boring 
very quickly holes straight downwards; for the earth in contact with the 
moist woods very quickly forms a deadly fungus. 
As a matter of course the earth to be placed into the breeding boxes 
has to be previously treated by heat or boiling water to destroy all animal 
germ possibly destructive to the helpless soft-skinned pupee. Larvae and 
pupee are kept in darkness. 
For Bark and Bast loving larvae, 7. ¢. such found under the bark of 
diseased trees, such as some Buprestidae, Longicornia, Cucujus etc. cut 
with saw and hatchet pieces of the infested tree with the bark about six 
inches square about 1 inch thick take some of the rubbish and sawdust 
and the larvae and when at home place them under the bark. Several
