94 Mr, Kir BY on Mr. W. S. MacLeay's 



Mr. W. S. MacLeay, in his acute and learned Hora. Entomo- 

 logical has furnished the naturalist with a clue which, if heedfuUy 

 followed, will enable him to guide himself through all the intri- 

 cacies with which the circumstance here mentioned has perplexed 

 his path. This gentleman has first stated with clearness and 

 precision the distinctions, so often before confounded, between 

 real affinity and those resemblances which are merely analo- 

 gical ; and has proved satisfactorily, that there exist between 

 numerous objects in every department of nature striking coinci- 

 dences as to external characters, which do not indicate that they 

 are related to each other, or should be placed together in a na- 

 tural arrangement. 



In confirmation of the doctrine here alluded to, I have the 

 honour to present to the Linnean Society a description of three 

 new genera of insects which appear to wear the face of a tribe 

 to which they do not belong.
