Psyche 
[March 
that several predaceous Hemiptera from Cuba are strikingly 
marked with the same brilliant red and sharply contrasting 
black colors as are seen in Callotriatoma. Thus Apiomerus 
burmeisterii Guerin and Enicocephalus cubanus Bruner are 
the only representatives of their respective genera (except- 
ing other closely allied Antillean species) with such colora- 
tion. Too much of the literature on mimicry and warning 
coloration is made up of idle speculation based upon museum 
specimens, but suggestions from this source may be of value 
if they point out where field work may best be concentrated. 
If the species just named occur in the same area, it would 
appear that they would be mutually benefited by combining 
their efforts along a single line of sematic coloration.” 
Edible Hemiptera 
In company with the inedible Hemiptera were placed 
several plain-colored species that were taken readily by 
Anolis. In addition to the following, two other unidentified 
bugs were quickly eaten. 
Mormidea pictiventris Stal (Pentatomidse) : The length 
is 8 mm., with cream colored marks on a brownish grey 
upper surface. Of five specimens fed to three separate 
Anolis sagrei, all were eaten within twenty-four hours. 
Oedancala cubana Stal (Lygseidse) : The length of cubana 
is 8 mm. and the upper surface is yellow brown. One ex- 
ample was eaten at once. 
Coleoptera Refused 
Pachnxus azurescens Sch. (Curculionidse) : This 10 mm. 
bluish cream weevil was not eaten after six days with an 
Anolis sagrei , whereas several greyish black weevils ( Lack - 
nopus near hispidus Boh.) of the same size were taken read- 
ily. 
Oedionychis fasciata Fabr. (Chrysomelidse) : According 
to Mrs. Blake the specimen used is actually a new species 
heretofore confused with fasciata. The pronotum and trans- 
verse elytral band are orange, and the rest of the elytra are 
bluish-purple. This 5 mm. beetle was not eaten after two 
days with an Anolis sagrei. 
A striking example of what is apparently warning colora-
