 no less experienced eye of the Sphex. Pray 

 compare the Cricket with the Locust: the

 tapering head, leaps forward by suddenly un- 

 bending his long hind-legs and continues this 

 flight with wings furled like a fan. Next 

 compare both of these with the Ephlppiger, 

 who carries his musical Instrument, two shrill 

 cymbals shaped like concave scales, on his 

 back and who waddles along with his pendu- 

 lous belly, ringed pale-green and buttercup- 

 yellow and armed with a long dirk. Place 

 the three side by side and you will agree with

 such dissimilar species, while still keeping to

 have an eye so expert that no man -— not 

 your ordinary layman, but a man of science 

 — need be ashamed to. own It. 



In the face of these singular predilections, 

 which seem to have had their limits laid down
