eb two subdivisions of the species, as demonstrable by material

once to the discussion of several points of more or 
suggested by this work on the Cychrini, one of 
of a reviewer to reéstablish a specific type, 
in the case of Arenans ovelis Mots. In my 
the genus Areeenus, | established a new type for ova/is, 
it forward now to test its reality among serious 
estigators. Ova/is, as | established it, is a species allied to renfrico- 
having two anal setae in the female and is not one of the allies of 
<tato s, of which alfernafus Mots., is a synonym, the type of the

type of Breasus ovelis Mots., now forms part of my col- 
apparent animus on the part of the author of the Cychrini 
has led him not only into many errors of identification, but uni- 
sed him to refuse me the benefit of the doubt where absolute 
was lacking ; this is particularly evident on p. 181, where he 
cuses me of making three species on identical material, based upon 
purely individual differences. I can assure him that be ts mistaken, not 
ly as to the material being collected in anywhere near the same 
_ bocality, but in the taxonomic value of the three forms, which might be 
considered subspecies of a single species, if one so desires, but could in

And this leads me to the most serious defect in the methods of this new 
___'W. Horn-Roeschke school, in failing to recognize the forms due to geo- 
_ graphic isolation, by which most species have undoubtedly arisen, for it
