conforms to the factors which have been considered to' make for 

 conspicuousness. Table III. shows the distribution of this second 

 type of pattern. At a short distance the central patterned area 

 will become blended and give rise to a light grey tone, and the 

 insect then has an appearance similar to the type first considered. 

 As before, it can be seen that out of 18 genera, 7 are protected 

 and 7 mimic: in this case, therefore, the conspicuous pattern 

 is accounted for in the case of 14 out of the 18 genera ; 4 remain 

 unaccounted for. It is noteworthy that in all cases the sexes are 

 alike. 



Table III. 



Conspicuous pattern combined with an absence of secondary 

 sexual dimorphism is so frequently associated with a protected 

 species, that- attention must be drawn to the fact that some of 

 the unaccounted-for genera in both tables may be protected 

 genera, although not mentioned as such in the work consulted. 



^ Finally, all the insects which are mentioned by Moore as being 

 either protected by ill-flavour or mimicked by other species, are 

 briefly considered in order to see whether or not they present
