seem advisable, as the majority of patterns are composed not only 
of a chief motive, but at the same time of one or more accessory 
motives, the latter often representing the remnants of the original 
design. For instance in the pattern of Cleitamia the light areas 
between the dark bars may, as argued above, be considered as 
coalesced light spots, and precisely these spots constitute the original 
pattern. 
Therefore it seems preferable simply to adopt the names of species, 
genera and families for the patterns which are shown in special 
clearness and completeness by them, e.g. the astrolabei-pattern, the 
scatella-design, the Pterocerine-system of bars. It should however 
never be forgotten, that these patterns (modified in sundry details), 
may equally well occur in other genera and even families of Diptera, 
and are also found in other orders of insects, it thus becoming a 
matter of chance, in what group of insects a characteristic type of 
pattern is first remarked and named. 
As it becomes evident, that between these different types of design 
a genetic connection really exists, so that they can be arranged ina 
series, leading from the most primitive and regular to the farthest 
modified and most capricious, and that this series is the same for 
different interrelated genera and families, the conclusion, that this 
correspondence roots in relationship, is a natural one. I accept it in 
this sense, that the common ancestors of genera and wider groups 
of interrelated forms already possessed these different patterns, which 
passed into the hereditary predisposition of their descendants. 
In this way.the study of Diptera-wings has led me to the same 
general conclusion, as I was brought to by the intercomparison of 
Hepialid-wings, “that the motives and patterns of the colour-design 
are older than the genera and families which display them.” 
Dr Mryrre has also noticed the phenomenon of the corresponding 
series of patterns, as is shown by his remark in the opening sentence 
of his paper: “It is only necessary to look over any tolerably extensive 
collection of Diptera, to become convinced, that in those families, 
where coloration occurs, the design may be widely different in the 
several forms belonging to them, a family-character therefore not 
being presented, while on the contrary different families often show 
the identical patterns” (the italies are mine). 
And again on page 75: “therefore the various motives often return 
in the different families”. 
In this feature pe Mrtsere however does not see anything more 
than a proof, that wing design in different families has developed 
in similar ways and so should be considered as a case of parallelism.
