aragonensis rezniceki—just as, without recognising the difference 
of species, I had seen the first generation of aragonensis rezniceki 
(=meridionalis, Tutt) overlapping typical cor ydon—Dr. Verity, 
by further and careful observation of both emergences, is able to 
establish the fact that corydon, Poda, is a single-brooded species. 
preceded and succeeded seasonally by a separate though closely 
allied species having a superficial resemblance to corydon which 
has deceived entomologists from the days of Rambur and 
Gerhard onwards, into belief of their identity. 
The deductions drawn by Dr. Verity are presented in tabular 
form as follows:

Incidentally Dr. Verity’s discovery throws light upon another 
doubtful chapter of my experiences with ‘“‘corydon.” On 
October 17th, 1902, I found myself unexpectedly at Digne 
returning from a late autumn visit to Beaulieu in the Alpes- 
Maritimes. On the one afternoon available, a warm and sunny 
day with indescribable beauty of autumn foliage still vivid in 
memory, I strolled along the footpath on the right bank of the 
Bléone, familiar to most Digne collectors, though I have never 
found it a very productive locality, and usually have had to

The Rivieran races, as then known, are examined and discussed at length in 
Tutt’s ‘ British Butterflies,” vol. iv, pp. 45-51 (1910). They include var. 
meridionalis, Tutt, first described, but as Dr. Verity insists without reference to 
the true distinguishing coloration of the underside, in the ‘ Entomologist’s Record,’ 
vol xxi, 290 (1909). 
Var. rezniceki predates meridionalis by five years (‘ Ent. Zeits.’ Guben, vol. 
xviii, p. 117. 1904), but Tutt’s criticism of Bartel’s comparisons of his variety with 
other forms of the species, as it was then supposed to be, deserve careful considera- 
tion. In my opinion he rightly evaluates Bartel’s conclusions.
