SOME EXPERIENCES IN LARVAE REARING. 



BY ROBERT BUNKER. 



(Continued from page no, vol. i.) 



Occasionally we find a rare larva that has been stung by some 

 saucy ichneumon fly, and if we can save it in the manner de- 

 scribed on page 109, it will certainly be a great gain. Of course 

 it must be done within a few days after the young worms have 

 entered the body of their host, or it will be of no use. The in- 

 ference to be drawn from this kind of treatment is that the chlo- 

 roform penetrated the body of the larva and destroyed the young- 

 parasites, but was not in sufficient quantity to injure the larva. 



Can the pupa of Darapsa versicolor remain under water two 

 weeks without injury ? The past two years I have bred this fine 

 species from eggs found on the button bush ( CephalantJnis occi- 

 dentalis) and last year's catch of eggs was a surprise to me, be- 

 cause the low ground where the bushes grow was submerged for 

 two weeks, and of course the pupa must have been under water 

 that length of time, and yet when the proper time came around 

 I found eggs. Some may say the eggs may have been laid by 

 females that came from a distance, but that could hardly be, as 

 the nearest bushes are six miles distant. Mr. Hulst has written
