Anolis seems to refuse all bright red and blue and red and 
black insects. If this should turn out to be true, then there 
would be a mutual Mullerian reinforcement of mimicry by 
warning coloration. 
Professor Brues’ photographs show that the pattern ap- 
pears in ultra violet light in only one instance but is more 
or less present in the longer wave-lengths emitted by fluores- 
cense . 2 Apparently the visible spectrum must be approxi- 
mately the same for Anolis and man. Certainly, the testing 
of the visible spectrum of Anolis would be a pertinent study. 
EXPLANATION OF PLATE I. 
Figs. 1-33. Insects used in mimicry and warning coloration experi- 
ments. Unless stated otherwise, the photographs were taken by white 
light. 1, Oncopeltis fasciatus; 2, by fluorescent lights; 3, by ultra violet. 
4, Euryophthalmus sellatus ; 5, by fluorescent light ; 6, by ultra violet. 
7, Mormidea pictiventris ; 8, by fluorescent light; 9, by ultra violet. 10, 
Dysdercus andreae; l 1, by fluorescent light ; 12, by ultra violet. 13, 
Calocosmus venustus ; 14, by fluorescent light ; 15, by ultra violet. 
16, Crypt ocephalus viridipennis. 17, Cryptocephalus commutatus. 18, 
Cryptocephalus 5-punctatus. 19, P achy hr achy s parallelopedus. 20, 
Drapetes hicolor. 21, Thonalmus aulicus (small specimen) ; 22, by 
fluorescent light; 23, by ultra violet. 24, Oedionychis n.sp. (near 
fasciata). 25, Pachnaeus azurescens. 26, Lachnopus near hispidus. 
27, Trichrous divisus Chev. ; 28, by fluorescent light ; 29, by ultra violet. 
30, Trichrous pilipennis. 31, Callopisma adjuncta. 32, Anoplischius 
venustus. 33, Clialepus sanguinicollis. 
2 The photographs were made with a mercury vapor source with quartz 
condensing lens. To register reflected ultra-violet light a dark purple 
filter excluding wave lengths longer than 4000 angs. was interposed be- 
tween the source of light and object. To register fluorescence, an addi- 
tional filter excluding lengths below 4000 angs. was added, between the 
object and the camera lens. Photographing by white light was done 
with tungsten filament flood-lights, without filter, on a panchromatic 
emulsion.
