I regret that I cannot give you any information respecting the ha- 

 bits, food, reproduction &c. of these interesting tribes, for not making

 abdomen at the broadest part of the circumference, might plainly be perceived many 

 oval bodies, which, on breaking the skin, proved to be ova enclosed in a membranous
