Regarding the colours, they may be either aposematic, or 
procryptic, or of such a nature that one cannot class them 
in either category. . 
One had also to consider that there are insects which, 
from freely exposing themselves, appear to have what may 
be termed “ aposematic habits,” although such habits may 
not be associated with conspicuous colours. 
Likewise there are insects whose colours do not seem 
especially to harmonise with their surroundings, yet their 
habits are like those of typically procryptic insects. 
AA In this class I put the typically aposematic insects 
of bold and fearless manner, showing conspicuous 
colours freely exposed. 
A Comprises the less conspicuous, but still conspicuous 
and exposed species. 
a In this class are the insects which have aposematic 
habits, although their colouring does not make 
them conspicuous. 
PP These are the typically procryptic insects, concealed 
by their extreme degree of resemblance to the 
colours, and often shape, of their immediate 
surroundings. Attitude often plays an important 
part in increasing the resemblance. 
im Insects of self-effacing habits, concealed on the 
whole by dingy colours or a general resemblance 
to their surroundings. 
p This class contains insects of retiring nature, whose 
colours cannot be said particularly to aid in their 
concealment. 
C This letter implies that I do not see my way to 
putting the insect in any of the other groups, 
v.e. it is a confession of ignorance ! 
Regarding the edibility, I have made six categories. 
+-+ This is the class of extremely edible species always 
eaten greedily, without hesitation, and with 
evidence of relish. 
-|- These insects are eaten with relish, but are first 
looked at for some time, or may be tasted. 
hy In this class come those species which are eaten 
doubtfully, or may be refused, after tasting, 
smelling, or pulling about. It must be remem- 
bered that this implies a certain degree of dis- 
tastefulness,
