It is clear that the pundidata unit shows various specializations 

 in both coloration and structure of the male subgenital plate. 

 After careful consideration of the considerable series of this 

 complex before us, we are convinced that none of the different 

 conditions developed by that species have as yet progressed far 

 enough, or become sufficiently constant, to warrant the recognition 

 of geographic races. On the other hand it is evident that reticu- 

 losa, craticula and cuprea have, with pundulata, all been derived 

 from a common ancestor, but have reached distinctive and con- 

 stant degrees of specialization fully worthy of specific distinc- 

 tions. Of these reticulosa shows very marked color specialization, 

 accompanied by slight changes in the male subgenital plate; 

 cuprea shows differences in the same features but developed along 

 wholly distinct lines, while craticula not only shows distinctive 

 features of facial color pattern, but also the maximum condition 

 of specialization of the type of male subgenital plate found in the 

 species placed by us in the first group of the West Indian complex.

This insect, though being, with its geographic race, distinctive 

 as the only species of the genus showing decided reduction in the 

 organs of flight, is very closely related to C punctulata. In fact 

 the only diagnostic features besides those mentioned above are, 

 the normally constant form of the median production of the male 

 subgenital plate; the distinctly less slender form of the female and 

 less produced subgenital plate, and in both sexes the buffy general 

 coloration tinged with cinnamon (never olivaceous) to varying 

 degrees. The male subgenital plate, though not more distinct 

 from the typical condition found in punctulatus than are occa- 

 sional specimens of that species showing abnormal features,-^ is
