object. Just keep the skin full of air, and place it in 

 the oven, holding it there until dry ; do not let it 

 touch the sides, or you will scorch it. Green larvae 

 lose their colour during the process, but this is 

 remedied by inserting a grass stem into the body, 

 down which pour a small quantity of dry colour ; 

 shake this about inside the body, until coloured all

 globator, I have been able by inspection to satisfy 

 myself as to the true female. In other cases where I 

 give the name of the female, it will be understood 

 that I am justified in doing so, only from its resem-
