274 ANNIE H. PRITCHETT. 



quite similar to the bark of trees that it frequents, and possesses 

 a very unpleasant odor. 



Fnlgorid. Introduced November 5, November 6. This lan- 

 tern fly is almost impossible to detect when at rest upon the 

 trunks of the cedars and arbor-vitse which it frequents. The 

 upper wings and exposed portions of the head and thorax are 

 somber gray, the almost transparent wings showing a tinge of 

 pink when spread. The under wings are either entirely black or 

 have a small white spot near the center. The posterior dorsal 

 portion of the abdomen is bright red or deep orange, the re- 

 maining portions of the body being black. The insect shows 

 perfect protective coloration at rest and a rather typical warning 

 combination in flight. The insects were eaten at once by the liz- 

 ards when seen in motion. 



COLEOPTERA. 



Chauliognathus scutellaris Lee. Although this beetle is colored 

 black and yellow it appears to be palatable. May I five were 

 introduced. The first was taken by the lizard that sampled the 

 Lygceid, tasted a little, and rejected. However three others were 

 eaten by a second lizard and the last beetle by a third. May 4 

 twenty beetles were introduced and all were eaten without any evi- 

 dences of unpalatability. On May 5 four were introduced just after 

 the four Lyg&ids. The first was carefully examined before being 

 eaten ; the second was tasted and refused by another lizard ; the 

 others were not noticed, as was also the case when seven were intro- 

 duced the following day. The lizards were probably too well fed, 

 for since then, May 1 1 and 1 3, they have eaten all that were offered. 



Epicauta sp. November 3. This black blister-beetle was 

 tasted and rejected immediately. Unfortunately no more speci- 

 mens were found. 



ZopJicrus lialdcinani Salle. This very hard Tenebrionid beetle, 

 conspicuously colored in black and white, was introduced Nov- 

 ember 9 and removed alive December 13 during which time no 

 attempt to take it was seen. Specimens experimented with Nov- 

 ember 12 and May 5 gave the same results. 



Lncanns dauia Thumb. This black, horny beetle was intro- 

 duced November 17 and died January 7; during this time the 

 lizards never tried to take it.
