Fabre's Writings

 patriarch of entomology in those days, wrote 

 the author a most eulogistic and encouraging 

 letter; happy to have directed his researches 

 toward discoveries which he himself had not 

 suspected, the venerable scientist emphati- 

 cally exhorted his young friend to continue 

 his journey along the path that was opening 

 before him, a path so full of promise. 



Some time after this he published another 

 entomological work which was by no means 

 calculated to disappoint the hopes aroused by 

 the first. It dealt with an insect related to 

 the Cantharides, the Sitaris humeralis, and it
