FEEDING LIZARDS WITH COLORED INSECTS. 2JJ 



whole specimen. The color of this scorpion would seem to 

 afford it efficient protection. This, together with its flat form, 

 frequently prevents its being noticed by a casual observer when 

 the stone under which it rests is overturned. 



MYRIOPODA. 



Jit/ns (Spirobolus) multistriatns Walsh. The specimen intro- 

 duced November 15 was not molested, but when two were intro- 

 duced February 12 a lizard bit off part of the head of one Jitlus. 

 Both specimens died after a few days, neither being eaten. This 

 myriopod has a hard integument and is defended by means of an 

 acrid secretion that is thrown out from the repugnatorial glands 

 along each side of the body. It has the habit of coiling up and 

 remaining quiescent whenever it is touched. This action makes 

 the lizards suspicious of it. 1 



EXPERIMENTS WITH GERRHONOTUS INFERNALIS BAIRD. 



The favorite foods of these lizards are crickets, grasshoppers, 

 spiders and scorpions. A few Hemiptera were eaten also. 



LEPIDOPTERA. 



Anosia plcxippns Linn. April i, April 2, April 4 (three). 

 None of these specimens were eaten. 



Papilio (Lturtias) pJiilcnor Linn. March 26, March 30, April 

 6. All were examined and rejected. 



Pyramcis cardui Linn. November 17. Offered and refused. 



Pyrrhancca andria Scudder. November 9. Refused. 



Colias eurytlicuie Boisd. March 30, April I (three), April 6. 

 On the latter date the butterfly was taken by the wings but soon 

 dropped, and all others were refused entirely. 



1 Sceloporus floridamis is badly infected with an interesting mite which attaches 

 itself under the scales of the lizard until sexually mature and then crawls up on 

 the wooden part of the cage to oviposit. The eggs are placed in a peculiarly con- 

 structed palisade and hatch as a six-legged larva that appears identical with the ordi- 

 nary " red bug." The adult has a pubescent black integument ; the head, anus and 

 four pairs of legs are bright red. The legs are arranged in groups, two pairs being 

 situated on the anterior portion of the body and two in the posterior region. Mr. 

 Nathan Banks believes that this form may represent a new genus since it is the only 

 lizard parasite that has been taken in this country, and appears to be closely related 

 to the Italian genus Geckobia.
