FEEDING LIZARDS WITH COLORED INSECTS. 2/5 



Harpalus caliginosus Fab. This beetle is large, black and 

 rather hard, nevertheless one was eaten December 2, one De- 

 cember 12 and another partly eaten January 8. Four remained 

 dead at this date. Their odor is offensive. 



Brachynus sp. When seized this beetle ejects a strong, volatile 

 acid with a sharp, audible report. This always surprised the 

 lizards ; nevertheless, of the four beetles placed in the cage three 

 were eaten, but the last refused. Two more were introduced Feb- 

 ruary 26 and one March 5, which afterward disappeared and pre- 

 sumably were eaten. 



Brachynus sp. April 3. This beetle, larger than the pre- 

 ceding species, was eaten at once. 



Calosoma angulatus Chev. and 



Pasiinachns depresses Fab. were introduced March 17. The 

 lizards attempted to catch them, but failed, and soon gave up the 

 chase. 



Chlanius orbits Horn. The odor of this beetle is quite offen- 

 sive. March 9 one was eaten at once. On March 10 two lizards 

 tried to catch a specimen but failed repeatedly. They appeared 

 to notice the odor and gave up the chase. On March 23, how- 

 ever, the lizard that ate the former now ate another, and still a 

 fourth was eaten April 3, but with evident disgust. 



Cantliaris fiihnpennis Lee. This large blister beetle has the 

 typical warning colors of black and yellowish-brown and is 

 further protected by a disagreeable secretion that exudes from 

 the joints of the legs when the insect is seized and which is 

 capable of producing blisters. Four of these beetles were intro- 

 duced May 19 and each was seized at once, then quickly shaken 

 off. The lizards eyed the beetles intently, but made no attempts 

 to take them. These specimens were removed and introduced 

 again the following day. Only one beetle was taken this time 

 and it was quickly rejected. On May 21 several beetles were 

 again introduced. One was caught and quickly rejected and no 

 further notice was taken of them unless they crawled upon the 

 lizards, in which case they were shaken off violently. 



DIPTERA. 



Musca doincstica and Stoino.vys calcitrans. A small lizard of 

 this species (Sccloporns floridanus} soon became so tame that it
