FEEDING LIZARDS WITH COLORED INSECTS. 



Diabrotica punctata Oliv. February 13. These green-and- 

 black beetles were probably too small for the lizards to perceive. 



Chlcenius orbus Horn. March 7. One of the lizards ran up 

 to examine the beetle but when near turned aside, evidently dis- 

 couraged because of the disagreeable odor, and did not try again 

 to take it. 



Pasimachns- dcpressns Fab. March 17. The beetle was ex- 

 amined and refused. 



Calosoina angulatns Chev. April 6. The beetle seemed never 

 to have been noticed. 



Chauliognathns scntcllaris Lee. May 4. The lizards seemed 

 to pay no attention to the beetle although fifteen 1 specimens were 

 introduced. 



Cantliaris fulvipennis Lee. Two specimens of this black-and- 

 yellovv blister beetle were introduced May 19. One was seized at 

 once by one of the lizards, chewed a moment, then dropped quickly. 

 The lizard began writhing and rubbing his mouth in the sand, 

 appearing much distressed. The second beetle was not noticed 

 by any of the lizards and was removed. On May 20 they eyed 

 the beetle that was introduced, but made no attempt to take it. 

 May 21, the specimen seemed not to be noticed. Others intro- 

 duced May 26 gave the save negative result as the preceding 

 experiment. 



H EMITTER A. 



Brachymena inyops. December i, January 24. This pro- 

 tectively colored, malodorous form was not noticed by the 

 lizards. 



Lygceid. May 5. Two specimens of this warningly colored 

 bug were introduced, examined and refused. 



Fulgorid sp. November 5, November 6. Several specimens 

 were eaten with evident relish. The bug was never refused if 

 alive, but never eaten if dead. 



HYMENOPTERA. 



Polistcs annnlaris. Linn. November 4, refused. 



Caniponotns sansabcanus Buckley. November 29 and Cain- 

 ponotus fcstinatns Buckley. April 13. These ants were possibly 

 too small to be noticed.
